Our Verdict

Hisense A7N [A7, A75N]

TCL S5/S551G

The Hisense A7N and the TCL S5/S551G are closely matched; in most cases, you should get the cheapest one you can find. The TCL has slightly better contrast, but in turn, the Hisense is a bit brighter, with a wider color gamut, but barely. The TCL's low-quality content smoothing is better than the Hisense's, but the latter's upscaling is noticeably better. The TCL is the better option for gaming due to its 120Hz support at 1440p and 1080p with a wide VRR range. Conversely, the Hisense is limited to 60Hz at all resolutions, with a narrow 48–60Hz VRR range.
