Pixel density is nothing without vibrance and good viewing angles. The EVO 3D looked very dull, and viewing angles were not so good. When we stuck it next to the iPhone 4, it looked horrid. The problem with that for me? I hate the iPhone 4. It's already been reviewed and I have seen it myself. The EVO 3D does not do 1080p in 2D, and the 3D 720p is two frames put together, which in turn will suffer severe banding as a few reviews stated. 3D is a gimmick, plain and simple. Hasn't caught on in the TV world, didn't catch on the 3DS and won't here. The other thing is that the EVO 3D uses the same QHD Pentile Matrix LCD, same as Atrix. Not a fan of that display.

Sensation vs iPhone 4 vs GS2. Sensation has same screen as EVO 3D. Just remember guys that QHD is not the display, that is the resolution. The panel is a SLCD on the Sensation/EVO 3D, OLED on the GS2, and IPS LCD on the iPhone 4.
