Design

The Sony KD55X77L has an attractive, minimalist design that will complement any living room. It features an elegant thin profile and slim bezels around the display that allow the 55-inch screen to take center stage.

The bezels measure just 0.31 inches thick on the sides and top of the TV. This creates a nearly all-screen effect when viewing content and movies. The slim form factor makes the X77L easy to mount flush on a wall as well.

The two detached feet that make up the stand have a stylish arched shape. They attach towards the edges of the TV rather than the center, keeping them out of the way. This stand design creates the illusion that the display is floating above the furniture it sits on. The feet can be set in either a standard configuration or brought inwards for a narrower setup.

Overall, the minimalist aesthetics and slim profile of the X77L allow it to blend seamlessly into living spaces. The thin bezels draw attention to the large, vibrant display panel. And the unique stand design adds flair while taking up a small footprint.

If you're looking for a slightly larger Sony TV with a similar high-end design, consider the Sony KD55X85K. This 55-inch 4K HDR TV features the same minimalist style and slim form factor as the X77L. It has ultra-thin bezels and an elegant stand with adjustable feet positions. The X85K stand has a central orientation for a more unified look.

In terms of display performance, the X85K also matches up well to the X77L. It includes Sony's X1 4K HDR picture processor for lifelike clarity and contrast. High dynamic range content shows vivid highlights and deep blacks. The Triluminos display reproduces natural, accurate colors across the entire spectrum. And X-Motion Clarity technology ensures fast action stays smooth and crisp.

Connectivity is robust on the X85K with four HDMI inputs, two of which support eARC for high quality audio pass-through. Built-in Wi-Fi and Bluetooth provide wireless streaming options. And it works with popular voice assistants like Alexa and Google Assistant. The sleek remote control has dedicated buttons for these AI helpers.

Overall, the Sony KD55X85K is an excellent alternative to consider if you want a bigger screen size than the 55-inch X77L. It brings the same gorgeous, minimalist design in a larger 4K package. Picture quality is similarly outstanding with HDR and advanced color. And smart features keep you connected. If you like the X77L but want more display real estate, the 55-inch Sony X85K is a great option worth checking out.

Display Quality

The Sony KD55X77L has impressive display quality that will enhance your viewing experience. It features a gorgeous 55-inch 3840 x 2160 4K Ultra HD resolution screen that delivers four times the detail of Full HD. With over 8 million pixels, images are remarkably sharp and detailed.

Colors are vibrant and accurate thanks to Sony's Triluminos display technology. It reproduces a wide color gamut, allowing you to see colors as intended. The 4K X-Reality PRO engine also helps upscale lower resolution content to near 4K quality.

With a high brightness rating of 350 nits and Dynamic Contrast Enhancer, the TV delivers bright, vivid images even in well-lit rooms. It has an excellent native contrast ratio of 5400:1 for deep blacks and brilliant highlights.

Viewing angles are also good on this TV. Sony's wide angle technology maintains color and contrast at wider angles so the picture doesn't degrade when viewing from the side. Overall, the display quality is truly cinematic and will please any viewer.

If you're looking for a slightly more affordable 55-inch 4K TV from Sony, check out the Sony KD55X80K. It shares many of the same display features as the X77L, including the 4K resolution, Triluminos color and 4K X-Reality PRO engine. The X80K has a lower peak brightness of 300 nits but still delivers a vibrant, detailed picture. Contrast is also excellent at 6000:1 native ratio. The design is nearly identical between the two models as well. So if you want to save a bit over the X77L without sacrificing much on picture quality, the KD55X80K is a great option.
