Our Verdict
TCL QM7K
TCL QM7/QM751G QLED
The TCL QM7/QM751G QLED and the TCL QM7K are similar TVs, although the newer QM7K provides slightly better image quality due to its vastly improved contrast ratio. Still, the QM7 is brighter in HDR, sometimes delivering a more impactful HDR experience depending on the scene. While its contrast isn't as good overall, its black levels are comparable due to its slightly faster and more precise local dimming solution. It's also a bit more colorful than its successor. Gamers will appreciate the QM7K's slightly faster pixel transitions and 288Hz support at 1080p.

TCL QM7/QM751G QLED vs TCL QM7K: Main Discussion

Native contrast would be much higher, same with the black uniformity, but the local dimming feature probably isn’t much better. The overall score would be higher on the 50-inch model, by quite a bit, but it’s hard to say just how much.
Thanks! And what about making a review of the 50" panel? I think that this review for IPS kills a lot this TV.
Unfortunately, it’s not likely. We have limited testing resources so we’re only able to test one size of each model.
Hi Adam,
For QNED80 2023, choose de 50" model.
About QNED80 2023 testing.
About QNED80 2023 testing, i saw that started last week. What size?
We purchased the 65" model. For context, we always buy the 65" inch models for TVs, unless a smaller size is available sooner!
