Samsung QN90A QLED vs Samsung QN90C/QN90CD QLED

The Samsung QN90A QLED performs better than the Samsung QN90C/QN90CD QLED on a few tests, but overall, the QN90C looks a bit better, especially with HDR content. The QN90C has better tone mapping and tracks the PQ EOTF better, so HDR content looks better and is more accurate. The QN90C also uses a different panel type that natively has a wide viewing angle without needing additional filters, so there's no Ultra Wide Viewing Angle layer. It results in a slightly smaller viewing angle on the QN90C, but there's no distracting rainbow smearing from overhead lights.
