It has HDMI but the HDMI port does not support full range colors (only limited) which makes colors on PS3 lack vibrance. Furthermore, HDMI quality with this model is not good in general. This monitor was one of the first with HDMI so I'm not that concerned about it.
So I thought one solution was to convert HDMI to DVI. Works, full-range colors are now supported. Colors and black levels are much better. Overscan is disabled.
On PS3, image quality is fine too but regular text in particular looks weird. Somehow pixelated when looking at it from desktop distance (especially noticeable on smaller, regular text - particularly on websites with the PS3 web browser). I do not get this effect when I connect my computer over DVI. I do not get this effect with Xbox 360 over VGA.
