D-Sub vs DVI

[dave518]

Most moniters i have seen are connected by D-Sub but now i am seeing DVI connections and i was wondering which is better?

Thanks

DVI is much better. Very noticable difference on certain monitor/vid card combos. Things will be much crisper and clear.

HDMI/DVI > VGA/D-SUB 15 > Component > S-Video > Composite

There.

DVI is digital. D-Sub is analog. For CRT monitors, D-Sub is actually better. For digital displays like LCD's, DVI is much much better.

I have a 997DF, D-Sub will look better?

Who knew!

Thanks a bunch guys, helpful as always

I never knew that s-video was that bad, i always thought component was good to, makes me wonder why HDTVs use that then

one more thing-- is VGA the same thing as D-Sub?

Component isn't bad its just not as good as DVI or VGA.
S-video on the other hand can't handle anything above 480i.

thanks to the both of you

I should have mentioned Component does 1080i or 720p. Which is roughly 3x the quality of 480i. So there is quite a big difference between it and S-video.
VGA obviously goes quite a bit highier but at that point if its for a HDTV or LCD you'd want to get DVI or HDMI to remove the analog signal of VGA or Component and go straight digital.

Ok, digital is always better huh, works for me

Thanks

Digital is if its a digital display. IE: Plasma, LCD, DLP or any other type of HDTV.
If its an analog display like a CRT then analog is going to be better.

WRT CRTs, not necessarily. It depends upon whether the video card or the CRT has the better DAC (digital-to-analog converter). I used to have an NEC FP1350X w/ DVI, and it was noticably crisper using DVI-D even with a Matrox G550. VGA cable quality is also a factor since it's carrying an analog signal, but I had an expensive, properly shielded cable when I compared the two.

How much better is the DVI vs VGA? Most DVI ones also have VGA connectors. Have you connected to each one and compare the quality? Photo? Text (I read DVI is sharper)? Vector graphics?

Please post your experience.

I'm trying to decide if I should return a Viewsonic VA902B (VGA only) and get a Viewsonic VA912B (DVI/VGA) . With DVI one, I can use my existing AGP card by connecting one to VGA and another to DVI. Will that slow down the video performance. My card is 128MB.

Thanks for your suggestions,

liu

on LCD always go wit hDVI if you can yah its sharper. With smaller LCD's IE 19" or below it doesn't matter to much at all but it depends on the monitor. I've seen some that look just as good on VGA.
With a video card with 1 DVI and 1 VGA you can use both to allow dual displays it won't slow down the video performace in 2D apps IE non games at all.
