Our Verdict
Hisense U8/U8N
TCL QM8/QM851G QLED
The Hisense U8/U8N and the TCL QM8/QM851G QLED are similar TVs, but the Hisense is slightly better overall. With local dimming enabled, the Hisense displays deeper blacks in a dark room due to its higher contrast ratio. The Hisense also has better accuracy in SDR and HDR, so it sticks closer to the content creator’s intent. On the other hand, the TCL is the brighter TV overall, but it has slightly worse reflection handling than the Hisense, so the two TVs perform similarly in a bright room.
