  • The best HDR performance of the Q900R-65” Samsung QLED 8K

    The best HDR performance of the Q900R-65” Samsung QLED 8K

    Samsung QE65Q900R 8K TV? So, the first question that most people will be obliged to ask is, why? We’re just starting to see 4k taking off with 4k Blu-ray that begin to be common and the first signs of 4k transmission take root, so why do we need 8k? It is a good question and a we will try to look and respond in the course of our past time with the QE65Q900R.

    The list of available applications is wide enough with all the major video services available, including all land capture services, iplayer with HLG compatibility, Amazon and Netflix support with HDR10 and also YouTube, which offers the 4k Player with HDR compatibility. It is unfortunate that you still do not have the opportunity to view the very small number of 8k videos in 8k. Vimeo is rumored to be able to view the 8k content through the app on the Samsung, but we found that this is not the case at the time of this review (2018 December). Other applications include Spotify, FB Video, Deezer, NowTV, UKTV, and Rakuten TV.


    Samsung Q900R

    With the current technology environment focused on voice support and much, the Q900R is covered with the SmartThings application and direct voice support from a remote microphone. You have the option to set up your TV with your smartphone application, and once you’re logged into a Samsung account, you’ll be able to share information between devices connected to the Smart Things application. Narrator also helps with the channel, application selections and settings and most of the I also understand a Scottish accent, right.

    The built-in TV tuner also works very well with excellent high definition image quality. EPG guides and even favorite lists save channel by jumping through the alignment of all channels. Access to channel navigation is quite easy with pressing the ENTER key and then directions up and down to bring the letters to each channel with ‘ Now and Next ‘ programs listed. If you don’t find anything to see here you also have the TV Plus app, which gives you everything you can buy and rent through the TV, including the latest versions of movies.

    The Samsung Q900R uses a 65-inch LCD Panel with a resolution of 7,680 X 4,320 and more than 33mm pixels giving a true resolution of 8k. It has a complete attenuation of the local backlight matrix (FALD) using only in 500 zones and when combined with the new Quantum 8k processor can use the AI technology and advanced algorithms to intelligently control The local attenuation to stop the bloom and the halo effects from being present.


    SAMSUNG QE65Q900R

    The Q900R also uses advanced upscaling to ensure that the content is seen at its best. This is very important as the native 8k viewing material is hard to reach at this time in time. Manufacturers could launch 8k televisions now, but the success of these early models is reduced to how good video processing and scale performance is. Once again, Samsung uses artificial intelligence and automatic learning to Make sure the magnied images are the best they can be.

    Obviously, the SD material can look bad even in an HD panel, so trying to show this in the Q900 is perhaps asking miracles of the best image processing available. However, by using automatic learning with advanced databases and analyzing the exact content and images that customers are viewing, IA works to make these images look the best they can. When you find new ways to improve scale and other image parameters, Samsung sends this as a firmware update for Q900R TVs in consumer households. As such, you are constantly looking to improve the performance on offer.

    The Samsung Q900R uses an 8k panel going with the local full-attenuation technology of arrays and advanced mitigation algorithms. The uniformity of the panel was very good, in fact, without obvious opacity or grouping of light and no perceptible dirty screen effect (DSE) at any level of uniform brightness. There were some very light vertical bands seen occasionally with very bright content, but with the display of football (or other sports or content with large areas of a color during the camera pans) was not noticeable unless you went to Buscárla. And even then it was really hard to see unless you were making a point of searching and continually sending torture evidence to take it. In the normal view, it is barely perceptible and we only mention that it is complete in our evaluation.

    Samsung has had a strong gaming performance for a number of years and the Q900R continues that tradition. Many players who use their screens for hours have gravitated to LED LCD screens, because there are no problems with storage or Burn-in, and the super-fast input delay. With the automatic game mode change as soon as the Q900R detects a game console, and an input delay of 16.7 MS for the SDR and HDR games, there is no doubt that Samsung is still impressing in this area.

    The HDR game is also an intense experience with excellent brilliance, strong specular reflexes and deep black levels when viewed from the front. The colors are excellent even with a superb saturation without being overly squeaky. The sharpness is also excellent and the rise to 8k is also very good, with no obvious visible artifacts. In General, the Q900R makes a great case for himself for serious and even casual gamers – with deep pockets, of course.

    If we just look at the side of 8k-resolution of things you might rightly say that it is perhaps early for the part where we have no native 8k content to see on it. Samsung is aware of this and that is why they have spent the time and budget of R&D creating automatic learning and AI technology to ensure that consumers can use the Q900R with all the content and resolutions currently Available. In addition, they are developing LED LCD technology and want to push that as far as possible before something else takes its place. There will be competition of OLED coming CES in a few weeks to make even the 8k story even more interesting. I just think you can make the decision to buy at 8k now with the lack of content available.

    But moving away from the native 8k part of the story and looking at the Q900R as a 2018 LED LCD TV, it really is a fantastic example of the technology given the HDR and image quality on offer. The climb is fantastic with HD and higher resolutions, with 4k it looks really gorgeous with small signs of any running scale. Fald backlight and advanced local mitigation algorithms are also impressive and work really well with the vast majority of display materials. We met some small flaws, but again these were fixed by the firmware and Samsung certainly intended to further improve performance in the future.

    There is no doubt in my mind that this is one of the best LED LCD’s available at this time and it is also the best HDR interpreter I have seen this year with its excellent black levels, breathtaking shadow detail and excellent color volume performance. In addition, specular reflections and general pop with HDR content are impressive. Given its maximum brightness of 2075 nit, it handled the contents of 1000 and 4000 nit with minimal pitch mapping and no clipping at all, resulting in some stunning images on the screen. The only downside to this is the obvious angle of view problem with LCD and moving off axis results in the return of disabled and flowering, but seen as expected and front, is really impressive. There is no doubt that Samsung has really shifted the performance level of LCD led to a couple of nots this year.

    The last part of the puzzle to mention is the price point of the 65 inch model that we are looking at here. In some respects it looks incredibly reasonable for a brand new 65-inch 8k TV at a price of £4999. In fact, looking back a few years to the first 4k screens in this size, it seems almost a bit of a bargain. But it also has the opposite view that could be seen as a Q9FN but with a high resolution screen, so it looks expensive. Only you will be able to tell if it is personally acceptable, but you have found the most advanced Samsung LCD TV with AI Auto learning technology and the first level improvement in a future package-proofed 8K resolution. photo:Samsung

  • Philips OLED technology TV 55P OS901F/12-Fantastic!

    Philips OLED technology TV 55P OS901F/12-Fantastic!

    Right from the off this 55in TV tickles you in all the right places. Its bodywork looks crisp and clean with slender lines and a bold, metallic finish. The gleaming soundbar hanging from its bottom edge promises better audio quality than you’d generally expect from a super-slim display, while the blade-like table-top legs do their best not to upset your Feng Shui. This being a Philips-branded TV, there’s the small matter of Ambilight to consider. This finds bold halos of colour radiating from the left, right and top edges of the bezel, via in-built LEDs. This can both make long-term viewing more relaxing on the eyes and increase your sense of immersion in what you’re watching. Do, however, restrict Ambilight’s brightness to around level two or three, and don’t set it to react too aggressively to changes in the image content or you’ll get an attention-grabbing light show. The Philips 55POS901F is well equipped with connections, including four HDMIs (all capable of 4K HDR at 60fps) and three USBs. The bulk of Philips’ online content options come courtesy of the Marshmallow version of Google’s Android TV platform, backed up by a smaller collection of apps housed under Philips’ own proprietary smart TV system.

    The Philips app collection is integrated fairly neatly into the Android TV home page. Of the latter, I’d still prefer greater opportunity for customisation and a better sense of presentation priority. But I’ve been saying that for ages and Google isn’t listening. BBC iPlayer is the only one of the UK’s main catch-up TV services supported by the TV’s smart system. And, at the time of writing, the Amazon app only supports 4K, not HDR. The Netflix client, however, is fully up to 4K and HDR speed. Almost. The 55POS901F doesn’t join LG’s OLED TVs in supporting Dolby Vision HDR, a format that’s now available on both Netflix and Amazon, and will be supported by Philips’ own 4K BD players. Philips has, however, confirmed that the TV will be upgradable to support the Hybrid Log-Gamma format in the future. Bear that in mind if you’re shopping for a TV to cover all bases. The TV is supplied with a double-sided remote control – the back panel houses a QWERTY keyboard to make it easier to enter text into video apps, etc. It also has a centralised touchpad and voice search function. Philips says that the TV will display an onscreen message when the remote’s batteries are low.PhilipsPOSF

    The Perfect Pixel Ultra HD processing engine driving the 55POS901F is Philips’ most powerful, featuring elements aimed at boosting contrast, colour, motion clarity, detail… every aspect of picture quality, basically. This may alarm the sort of AV enthusiast who prefers pictures to be tinkered with as little as possible on their journey from source to screen. However, powerful processing – when applied sensibly – certainly can improve image quality. This is a fact borne out by the Movie picture preset available here. This deactivates most of the processing engine elements, and delivers pictures that look less convincing and enjoyable than tweaked versions of some of the other presets. You need to pick your way through the features of Perfect Pixel Ultra HD and activate/deactivate to suit your tastes. For instance, I’d recommend turning off all noise reduction for 4K viewing, and only use the other processing options (especially the one that handles motion clarity) on their lowest power settings. At least Philips gives you the tools to make these corrections, though – and the result of your up-front tweaking efforts is some majestically good picture quality. The TV greets you with that familiar OLED impact when it comes to black level response. The shots of space around the Enterprise in the Star Trek: Beyond 4K Blu-ray feature black colours delivered with exquisite depth and naturalism. There’s not a hint of grey, nor any evidence of the sort of backlight clouding or striping around bright objects you would expect to see with an LED/LCD screen.

    SPECIFICATIONS–3D: No 4K: Yes. 3,840 x 2,160 resolution HDR: Yes. HDR 10 TUNER: Yes. Freeview HD; satellite HD CONNECTIONS: 4 x HDMI inputs; 3 x USB inputs; Ethernet port; headphone jack; RF input; digital audio output SOUND: 30W BRIGHTNESS (CLAIMED): N/A CONTRAST RATIO (CLAIMED): N/A DIMENSIONS (OFF STAND): 1,228.6(w) x 751.9(h) x 49.4(d)mm WEIGHT (OFF STAND): 17.42kg FEATURES: Built-in Wi-Fi; USB multimedia playback; DLNA multimedia playback; Perfect Pixel Ultra HD processing engine; 3-sided Ambilight; Ultra Resolution; Perfect Natural Motion; Micro Dimming Premium; YouTube, Netflix, Amazon and BBC iPlayer apps; Android TV; USB recording/pause live TV; QWERTY keyboard on supplied remote; HDCP 2.2 on all four HDMI inputs

    Clarity and sharpness are other strengths, and here Philips’ Ultra Resolution feature pays dividends. Activate this and you’ll see both native 4K and, especially, upscaled HD pictures looking markedly more detailed and crisp than they do on LG’s OLEDs. Sully’s New York landscape shots look so detailed, in fact, that they sometimes feel like they’ve crept beyond 4K. You need to reduce the Ultra Resolution sharpness setting a notch or two from its default position, though, or your eyeball enjoyment will suffer from noise and stressy edges. The 55POS901F proves excellent at motion handling. Even without motion smoothing in play, camera pans and fast-moving objects are crisp and free from judder. Use the lowest setting of Philips’ Perfect Natural Motion system and you can remove almost all judder without causing many unwanted side effects, or creating soap opera-style fl uid visuals. Although for some, one artefact is one too many. Philips’ in-built 30W speaker array sounds considerably better than the squawkers often used in super-thin TVs. The forward-facing soundbar delivers strong levels of clarity and attack in Star Trek: Beyond when the Enterprise takes on the baddies with the help of The Beastie Boys’ Sabotage, combining plenty of detail and punch with smooth, always intelligible vocals. A rear-mounted bass driver provides a decent amount of low-end heft, too, and none of the speakers succumb to distortion or crackling unless they’re driven to volumes well beyond anything likely to be comfortable for most rooms.

    With all types of content, this Philips set is routinely brilliant, and – as mentioned – more accomplished when it comes to the fi ner points of image quality than previous OLED models. But there are areas where it’s not as impressive, of which potential buyers should be aware. Firstly, brightness is limited in comparison to incoming rivals – the newer OLED panels in LG’s 2017 range should push nearer to 800 nits, while LED-lit LCD TVs are marching on into the high 1,000s. As I cover in the feature on p20, this makes the Philips 55POS901F relatively limited in the amount of colour volume it can deliver. I was also slightly disappointed that the lowest input lag measurement I could get from the TV was 55ms. This isn’t disastrously high, but is nearly double what competitive gamers would like to see. Nor does this set cater for those with 3D Blu-ray collections. In keeping with Philips’ strategy with LCD TVs, 3D has been jettisoned. It’s also worth pointing out that you can get LG’s OLED55E6 for around £2,500 these days, saving you £300 on the launch price of this Philips. That model is also confi rmed to be getting HLG support to compliment its existing Dolby Vision and 3D playback talents, and uses the funkier WebOS user interface. Even judged purely on its performance, though, Philips’ OLED debut seems more than worthy of its £2,800 ticket, and is a great way to kick off the next stage of the OLED revolution.

  • Roku Ultra 4K HDR Streaming Player-Great picture and sound quality

    Roku Ultra 4K HDR Streaming Player-Great picture and sound quality

    Roku has launched brand-new products that bring HDR /high dynamic range/ to 4K streaming while maintaining
    their simple menu structure. A variety of new models range from the Express player to a new best-of-the-line
    player,the Ultra.While both the Premiere+ and the Ultra support 4K and HDR,the Ultra has a few more
    functions for those who insist on the finest picture and sound.
    It’s proof of how far the streaming player has come from the low-quality picture of its 1st generation.

    When you create a Roku account, channels will easily transfer to the Ultra during setup.Right after you signed in on your iPhone’s web browser,it required less than 10 minutes to load 127 programs.During the
    sign-in procedure, Roku recommended various channels to include,such as Showtime,the Weather Channel,
    MLB, and NHL.Unexpectedly,the next screen offered a one-tap url to your Amazon accounts for Amazon Instant
    Video.Many other subscription channels offered a code that can be enter on their sites for
    activation, to avoid using the horrible onscreen keyboard for logins.roku player
    In fact,you never had to use the onscreen keyboard anyway, since the Roku Mobile Application for iPhone
    and Android uses the phone’s keyboard rather.
    More than just a remote control,the app can access the Roku channel store to add new channels, and it can
    cast media from the phone.The application also contains a “Play on Roku” function to quickly show
    pics via the Ultra.In addition to your phone’s gallery, it can access anything you’ve stored in some other photo
    applications, such as Instagram, Hydra,PicsArt, Snapseed, and Sony’s PlayMemories Mobile.With a tap,you can
    added audio to the slideshow by choosing one of your iTunes playlists.While it was simple to start the
    slideshow, you had to switch screens between managing the audio and controlling the slideshow.
    The Roku app provides voice search and personal listening via headphones connected to your
    phone, but the Ultra’s remote control has its own built-in mic and headphone jack port.4 direct channel
    buttons on the remote-Netflix, Sling TV, Hulu, and Showtime-help create a complete streaming experience.
    Like the now stopped Roku 4,the Ultra has a remote finder button on top the unit to help to make the remote beep,for those
    times when it slips between the couch pillows.
    Voice search on the remote finds channels as well as films and TV shows by title,favorite actor, and
    so on.Not like some other streaming devices that prefer the company’s own streaming app-think Apple TV
    and iTunes, or Fire TV and Amazon Instant Video-the Roku search is agnostic and includes results from
    many of channels.

    Roku’s Follow function debuted in 2015 to assist keep track of TV shows and movie titles when they become
    accessible to stream.While the application and the platform do the job with all the new Roku versions,
    the Ultra has a few additional hardware features for ideal performance.To help customers who do not have a fast wi-fi router or simply need the best network connection,Roku brought back an Ethernet port for significantly better streaming
    reliability (10/100 Base T, also on the Premiere+ model).And the Ultra has 802.11ac dual-band Wi-Fi if you do
    have a compatible router.roku player
    In addition,the Ultra is capable of Dolby Digital Plus;the player’s optical audio output can
    connect directly to an A/V device to accommodate complete digital surround sound. When you connected it up,the
    sound level of quality from Vudu HDX was clearly remarkable to that from Netflix,
    Amazon, and some others.Similarly,the 4K video on Vudu was excellent.

    The Ultra has delivered the high-quality performance of 4K HDR to the Roku system.No other streaming player has the search
    features,powerful remote app,and simplicity of casting images and music.
    It’s true that Follow, agnostic search,and Play on Roku are available on all current Roku types,but if you’ve
    stocked your home theater along with a 4K HDR TV, the Ultra is your perfect solution.
