TCL Q77K

Pros

• High refresh rate support (120Hz native, 144Hz via HDMI) at a very low price point.
• Excellent 'bang for buck' for basic streaming and casual gaming.
• Relatively wide viewing angles for an entry-level panel.
• Smooth operating system performance and stable user interface.

Cons

• Lack of local dimming leads to poor contrast and visible backlight noise in dark scenes.
• Low peak brightness (reported as low as 288-400 nits) makes it struggle in well-lit rooms.
• Poor upscaling and motion handling, particularly noticeable when watching sports.
• Underwhelming HDR performance, with some users reporting a hazy or 'off' look in Dolby Vision.

Caveats

• The 'QLED' implementation is described by some as a lower-tier version focusing primarily on green quantum dots.
• Many users recommend stepping up to the QM6K or QM6K Pro for a significant improvement in picture quality.
• Imperfections in the backlight are highly visible when the TV is used in a dark room.

Best for

• Budget-conscious gamers who need 144Hz support.
• Secondary rooms or casual streaming where high-end picture quality is not a priority.
• Users looking for a large screen size on a very strict budget.

Avoid if

• You primarily watch sports due to motion and upscaling limitations.
• You want a true HDR experience with high peak brightness.
• You frequently watch movies in dark environments where local dimming is necessary.
