Which is better for gaming?

The 50-inch QM6K. Its 144Hz native panel and Game Accelerator 288 reach higher frame rates than the 65-inch's 120Hz. Both have four HDMI ports and auto game mode.

Is the 65-inch worth the same price as the 50-inch?

Yes, if your room fits it. At $427.99 each on November 7, 2026, the 65-inch gives roughly 70% more screen area for the same money.

Which has better picture quality?

They use the same QD-Mini LED backlight and processing, so quality is close. The 50-inch lists Dolby Vision and HDR10+ explicitly; confirm the 65-inch's HDR formats before buying if that matters.

Will the 50-inch drop to $329.99 again?

It hit $329.99 on November 7, 2026, so a repeat during holiday sales is plausible. The 65-inch has not gone below $427.99 in the tracked window.

How far should I sit from each?

About 6 to 7 feet for the 50-inch and 8 to 9 feet for the 65-inch for mixed 4K viewing.

TCL 50" QM6K QD-Mini LED 4K Google TV vs TCL QM6K 65" QD-Mini LED Google TV

Both listings point to the same TCL QM6K panel, so the real choice is size versus price. The 50-inch QM6K is $427.99 at Amazon as of November 7, 2026, and has traded as low as $329.99. The 65-inch QM6K is also $427.99 at Amazon as of November 7, 2026, so at this moment the bigger screen costs the same. Buy the 65-inch if your room fits it; take the 50-inch only if space is tight or you want to wait for a sub-$350 sale.
