Actually, I am currently using for gaming right now and it looks beautiful on this monitor. I'm playing StarCraft 2, Deus Ex, Battlefield 3, and now Marvel Heroes on PC and it looks fantastic. I personally have no complaints. I also hooked up my Xbox 360 via the HD VGA Xbox cable and I play Halo4 and Call of Duty: Black Ops 2 and it's just awesome. So if you want to pick up this Asus VS238H-P 23" HD Monitor, then I honestly highly recommend it. Go for it buddy! I don't regret it and it was worth every penny that I spent.
The refresh rate is 60. I'm not sure I understand what you mean about the black looking perforated. The few games I have played the picture looks great across the whole color spectrum, you will want to adjust the settings. The default settings look like crap.
Hey Kamryn, not sure what a DVID is, but this monitor does have 2 HDMI ports. As I stated in my review of this monitor, I'd spend the extra $ for a 240Hz model if you're going to be watching much video content or using it for gaming. Hope this helps.
