The overall build quality of the Sony X77L is commendable, despite being constructed entirely from plastic. While the material choice may not be premium, it holds up well without any notable flaws. The back panel, predominantly a single large piece, exhibits some flex, though this is typical and unlikely to result in long-term issues.
The X77L 4K impresses with its solid color reproduction, offering a well-saturated and accurate palette right out of the box without the need for calibration. However, its limited color gamut hampers its ability to display the full range of colors essential for optimal HDR content viewing.
In terms of HDR performance, the Sony X77L falls short in brightness, resulting in subpar HDR picture quality. While it performs decently with SDR content, it may struggle in brightly lit rooms due to its slightly lower minimal brightness output.
The 75” model of the X77L utilizes an IPS panel, translating to mediocre contrast and shallow black levels, making it unsuitable for viewing dark content in dimly lit environments. However, in well-lit rooms, this issue is less noticeable, ensuring acceptable picture quality.
HD content shines on the Sony X77L, delivering crisp and detailed images with good clarity. Unfortunately, its black uniformity suffers due to the absence of local dimming, resulting in a grayish-black appearance.
On the bright side, wide-angle viewing remains impressive, thanks to the IPS panel, ensuring consistent contrast and color saturation even in rooms with expansive seating arrangements.
Motion handling during regular content playback is commendable, with minimal motion blur and smooth performance even during fast-paced scenes.
As for sound quality, the X77L delivers an okay performance, with adequate volume levels and clear dialogue. However, bass output is lacking, a common limitation in flat-panel TVs.
Externally, the TV’s rear appears plain and somewhat inexpensive. The inputs are recessed, making them difficult to reach when wall-mounted. To aid in cable management, the TV includes clips that can be attached to the feet.
Similar to its predecessor, the Sony X75K, the X77L stands out for being entirely flicker-free across all brightness levels. This feature is particularly beneficial for individuals sensitive to flickering, reducing eye strain during extended viewing sessions.
In ‘Game’ mode, the input lag is impressively low, delivering a smooth and responsive gaming experience. However, the ‘Graphics’ Picture Mode, essential for clear text display from a PC, suffers from unusually high input lag, rendering it impractical for regular use due to sluggish cursor movements.
Although equipped with an auto low latency mode that switches to the ‘Game’ Picture Mode, enabling it requires navigating through the HDMI signal format menu, a departure from previous Sony TVs. This feature is supported only on port 3, coinciding with the eARC port. Users employing a soundbar or home theater receiver will need to utilize alternative inputs and manually switch to the ‘Game’ Picture Mode to benefit from reduced input lag.
Regrettably, the TV’s 60Hz refresh rate limits its compatibility with the PS5 and Xbox Series S|X. Despite the auto low latency mode’s inclusion, it still necessitates configuration through the HDMI signal format menu, available exclusively on port 3. For those utilizing external audio devices, switching inputs and manually activating the ‘Game’ Picture Mode becomes necessary to achieve optimal performance.
The Sony X77L provides a decent gaming experience, boasting low input lag for responsive gameplay and an acceptable response time with minimal blur during fast movements. However, its gaming capabilities are hindered by its 60Hz refresh rate and lack of support for advanced gaming features like VRR. While equipped with an auto low latency mode (ALLM), its usability is limited by Sony’s decision to confine this feature to just one HDMI input, coincidentally the eARC port, rendering it less practical for gaming enthusiasts.
Pros:
Good accuracy prior to calibration.
Low input lag in the ‘Game’ Picture Mode.
Flicker-free performance at all brightness levels.
Cons:
Limited peak brightness.
Restricted to a 60Hz refresh rate with no VRR support.
ALLM functionality confined to one port.
As a desktop PC monitor, the Sony X77L falls short, but it suffices for PC gaming purposes. The ‘Game’ Picture Mode ensures minimal input lag for responsive gameplay, while the ‘Graphics’ Picture Mode correctly displays chroma 4:4:4. However, activating the latter significantly increases input lag, resulting in sluggish mouse movements. Consequently, users must choose between responsive inputs and clear text when using it as a desktop display.
For viewing sports in well-lit environments, the Sony X77L proves satisfactory. Its wide viewing angle accommodates diverse seating arrangements, maintaining image consistency from various angles. Although it handles reflections moderately and offers decent peak brightness, excessive glare may pose issues. With adequate motion handling and good gray uniformity, the central screen area remains clear during fast-paced action scenes.
Positioned as an entry-level 4K model in Sony’s 2023 lineup, the X77L slots above the X75L and below the less widely available X80L. Offering minimal additional features, it relies on Sony’s 4K Processor X1 for quality picture processing. Utilizing an ADS panel and lacking local dimming, it targets users seeking a basic TV for secondary rooms or moderately lit living spaces.
Resolution and Upscaling
Our upscaling assessment begins with a range of videos spanning various resolutions, from ultra-low-quality sources to 480p DVDs, and progressing to 720p and 1080p resolutions. We evaluate broadcasting signals, streaming content, and discs to comprehensively gauge the TV’s performance.
The X77L yielded mixed outcomes in this assessment. Regarding low-resolution content, the TV pleasantly surprised us. Despite the limitations of the X77L’s processor, the images appeared adequately sharp, preserving substantial detail. Text exhibited commendable clarity, devoid of significant aberrations.
Conversely, the X77L 4K struggled with low-quality streaming content. Macro-blocking was conspicuous, indicating the TV’s incapacity to effectively mitigate these artifacts. However, this outcome was predictable, given that such capabilities are primarily associated with top-tier units.
As an entry-level option, Sony’s X77L proves to be a respectable choice for a 4K TV. Its color accuracy and sharp, detailed imagery, enhanced by Sony’s top-notch video processing, offer a satisfying viewing experience. However, its noticeable drawbacks lie in its limited contrast and shallow black levels, particularly impacting the display quality in dimly lit environments when viewing dark content.
In summary, if you prioritize a solid picture quality that aligns with entry-level expectations and don’t mind forgoing the advanced features found in higher-end models, the Sony X77L 4K could be an ideal fit for your needs.
