QLED1Maker product pageus.tcl.com/products/q-class-4k-uhd-hdr-qled-smart-tv-with-google-tvRead 7 October 2026Exact-model maker Display Technology explicitly identifies QLED and its product description claims quantum-dot technology. Public exact-size review observes KSF phosphor producing red light, which does not establish absence of other quantum-dot components. The stored classification follows the explicit maker specification. It does not claim independent verification of all color-conversion components.

The introduction and gaming verdict explicitly say up to 1440p at 120 Hz, establishing that cap with Game Accelerator and resolution halving. Game Master and VRR are required for reduced-resolution 120 Hz. These rows describe accepted input resolution, not full delivered vertical detail. Public console prose also accepts 1080p at 120 Hz, but does not explicitly establish its absolute maximum, so that maximum row is omitted. Xbox HDR must be disabled for lower-resolution 120 Hz, while PS5 HDR works. Proper 4:4:4 is stated for common formats in Game Mode and PC, but the reduced-resolution 120 Hz row is not assigned 4:4:4.
