Our Verdict

Samsung Q80D [Q80, Q80DD] QLED

TCL QM7/QM751G QLED

The TCL QM7/QM751G QLED is better than the Samsung Q80D QLED. The TCL has better black levels, and its local dimming feature performs better overall, giving the TV better blooming performance and less noticeable lighting zone transitions. The TCL is also far brighter in HDR content, and it has a wider color gamut, offering a more impactful HDR presentation than the Samsung. The TCL is also better for gamers due to its faster response time and 144Hz support. That said, the Samsung is more accurate in HDR and SDR out-of-the-box, so consider it if you care about image accuracy.
