Gaming responsiveness belongs to the Q77K. Its 10-13ms input lag makes it the faster choice for competitive players.
Both TVs hit 144Hz at 4K, but the Q77K’s lower latency gives gamers the edge during fast-paced moments.
Picture quality strongly favors the QM8K. The QM8K’s QD-Mini LED technology delivers deeper blacks and more vibrant colors than the Q77K’s QLED approach.
You’ll notice this difference immediately when watching HDR movies or bright sports content.
Brightness is where the QM8K pulls ahead decisively. HDR5000 brightness means glare won’t wash out your image in sunny rooms.

Dimming precision matters for contrast. The QM8K’s LD3800 dimming zones create precise lighting control, minimizing halo effects around bright objects.
The Q77K’s full array dimming is solid but less sophisticated.
Color accuracy requires calibration on both models. The QM8K includes a new Filmmaker mode for better accuracy out of the box.
