My TV is RGBW, but it is OLED. Some RGBW LCD panels from LG in the past did not actually have RGB subpixels for every pixel which was a problem. The OLED ones do have RGBW subpixels for every pixel (so 32M subpixels). I would not use it as my computer display, although I am sure it could do it just fine. I do have a mythtv frontend connected to it, and due to HDMI 1.4 limitations on that machine, I have to force it to 1920x1080@60Hz rather than the 3840x2160@30Hz it likes to default to since my content on mythtv is never more than 1920x1080 but is often 60Hz. > Also: go for IPS or VBA technology.

Well sure but if your HDMI link is too slow, letting the screen do it is a better option than having terrible frame rate. > One exception: if a computer only does 1920x1080, you can let a > TV/monitor double the pixels in each dimension.
