I have a Philips BDM3270QP/00. It is a 32″ monitor with a 2.560 x 1.440 resolution. And it is amazing in my opinion. The best monitor I have had so far. The only downside is that it is not 4K. But picture qualitiy is outstanding, backlighting is even and lag is low.
Consoles I tested:
SNES, Saturn, PLaystation 1, original Xbox, PS2, Wii, Dreamcast
Everything worked fine with 100% compatibility (3x-5x and 480p –> 960p).
