If it's working good with DVI, it's likely an issue, driver or settings configuration in the properties of the video card. You also might want to make sure that you have the latest driver downloaded from your video card or computer's website.
I had recently purchased a 23 inch Samsung P2370MS LCD Monitor. I thought of connecting it to my pc through HDMI cable, but the outout is very fringy and the resolution is not matching . I tried all the setting but nothing worked. If i connect the same thing with DVI, everything works fine.Could anyone plz suggest me useful tios, so that I can use HDMI
