VGA and XGA are supposed to handle 720 p but many factors place limits on the ability to display 720 effectively. HDMI was developed specifically for HD, or 720 and up, 1080 being the goal. HDMI has now become the digital stndard interface. VGA is analog and 720p is a bit of a reach. A video card or even an external unit with the HDMI would be the PC approach, but the monitor may not have that interface. Once that conversion from analog to digital is done on the pc, then any unit with an HDMI port will work as a display. What inputs does the monitor have?? some come with DVI and that could be converted to HDMI. Many options available.
I am a movie freak, recently i bought a dell 26' LED monitor(model : 2420l) for a HD quality video's and creative 5.1 speakers. I have a motherboard(not sure of the model number) which the guy from the shop told me that its by default supports 5.1(soud), sound seems to be pretty ok. But regarding the picture quality, since I am using the VGA cable, picture quality is not upto the mark. The guy from the shop told me that I should be using a graphics card with HDMI connector(for 1080p quality).
Please advice me, if I use a graphics card with HDMI connector,, will I be able to get a good picture quality?
