Our Verdict

Hisense U8/U8K

TCL QM851G

The Hisense U8K and TCL QM851G are evenly matched, with only small differences. The TCL is a bit brighter in HDR and SDR, but the Hisense is more accurate in HDR and SDR. The TCL has slightly better image processing. Gamers might prefer the TCL, which has a noticeably faster response time than the Hisense. Ultimately, the Hisense is the better choice if you care about image accuracy. Otherwise, the TCL offers a slightly brighter image.
