But HDMI is way better.

HDMI is the same quality as DVI. The only difference is that HDMI transmits sound as well as video. DVI is used for monitors because its solely for video.

RAMDACS are the limitation with VGA. 2048x1536@**?hz is the max you can squeeze through a cable to the best of monitors.

**? I am googling it....

I guess a 400mhz RAMDAC can push 2048x1536@85 hz... but alot of cards nowadays have 450mhz.

For the most part, you'd be hard pressed to tell any difference on a "typical system" (a computer hooked up to a monitor that is < 2 feet away) between VGA, DVI, or HDMI by looking at it.

Now if you are going further than 6 feet away, I'd go with digital (either DVI or HDMI). The up side with HDMI is that with one cable you can also get audio.

But for 99% of the systems out there, there is really no difference and often boils down to what connector is on your video card and what connector is on your monitor.

If your monitor has DVI input, so use it and if not, stay with D-Sub.
D-Sub also depends on the monitor's ADC.
HDMI is better maybe because of the socket + audio.

I see no reason to discuss more kookoo.gif

From a visual quality standpoint, I have seen no discernable difference between VGA and DVI. What I have noticed however is that VGA is much more prone to have cable issues that cause the color to get screwed up. Guess this is because it is Analog. I recomend you stick with the DVI/HDMI since it is digital.

I have a Dell 18.5' 16:10 LCD.I was getting noise problems on display specially at lower resolutions like 1024 x 768 and specially on black color using VGA. Later figured out it was the problem with graphic card. Switched to DVI and problem solved. And display is slightly nicer(or may be I just think it is) but yeah the noise problem was solved by changing the cable rather than having to change graphic card. DVI thumb.gif

In simplest terms DVI is digital, VGA analog. Technically there is no limit to the resolution or refresh rate that either can carry (depends on data clock). Both are subject to EM noise, in case of VGA it usually shows as color distortion, in DVI as pixel snow. It is also worth noting that VGA capability is included in most common DVI cables which also gives the ability to passively "convert" from one to another (the signal was analogue to begin with though). In terms of quality - under normal circumstances its nothing that you can notice.

HDMI and DVI are not the same, while both are digital and similar they carry a different protocol. Due to the cable similarities though DVI signal can be transmitted over HDMI (which is what happens when you use a passive converter) and recently vice-versa too(so these days both DVI and HDMI are capable of carrying usb and audio signals as well as video). Pure HDMI is more strictly regulated than DVI though and has some additional options for image encoding.

Displayport is yet another standalone cable/protocol, directly targeting to replace DVI. Lice its predecessor though the cable is capable of transmitting DVI/HDMI signals for backwards compatibility.

When I had my Acer X223W LCD, I used VGA for one PC and DVI for another. When both were at native res and I auto adjusted on VGA, they looked identical. I could not tell the difference, although the acer X223W is one of the worst monitors i've had in terms of colors and contrast and all that so it might have been not good enough to notice a difference. That being said, I could not notice a difference on my ASUS VH236H either which is a much better monitor.

I honestly don't know what the resolution limit for VGA is, I can set my VGA CRT to 2560x1920 at 72hz, while almost everyone says the limit is 2048x1536 at 60/75hz, which clearly isn't the case.
