dvi to vga adaper

[Hilarion]

Simple question, does a dvi to vga adapter cause any loss of quality or lag like a usb to ps/2 adapter. Also, is there any diffrence in quality depending of the adapter.
Thanks

usually no difference. unsure of any lag but IF ANY it should be minimal

No. A DVI -> VGA adapter doesn't actually do anything but re-route existing electrical connections.

The DVI-I Standard (most video cards have these ports) includes the entire VGA interface on pins that arent used for a pure digital signal. A DVI->VGA adapter merely takes these pins and moves them to the VGA standard connector.

There's no difference, at all.

Now, realize that at resolutions above ~1600x1200, VGA starts getting fuzzy. At 1920x1200 and higher, you will definitely see the difference between DVI and VGA. Do keep this in mind.

For CRTs though, no worries on having a "real" VGA port on your card. NO difference here..

This is true, watch out for the 1600x1200 resolutions, it will start getting fuzzy. I have a dual setup and unfotunately my video card does not have dual dvi. That's when I know it's time to upgrade my pc.. it's getting pretty old.

Thanks for the anwser

hmmm...on a related note what is the difference between using a HDTV connector via components and running a DVI-->HDMI to the HDTV?

That's a good question. Basically, you won't see much difference between good quality component cables and DVI / HDMI even at 1080p.

Component cables are usually very well shielded, and the interface has lots of bandwidth. DVI / HDMI is a BIT better, but it's hard to notice. I would suggest going with HDMI in most cases, simply because it's a single cable that's easier to physically manage. It can also carry audio as we all know, but that's tricky, and pointless if you're going point to point from your PC to your TV.

HDMI's extra bandwidth is wasted for video currently, but if we start seeing 1080p60 content it will be needed. It also is very nice for the new high resolution audio formats on HD optical media that S/PDIF doesn't have the bandwidth (or DRM handshaking 😛) for.

Now, the component out from most PC's video cards is not exactly high grade. The breakout cable that my 8800gts came with has 3 pathetically flimsy component leads, which have female ends and are designed to be connected to a patch cable. I wouldn't even really consider using it on an HDTV, since a DVI -> HDMI adapter is like $10 from monoprice...

HDMI FTW, but not because it LOOKS SO FREAKING AMAZING OMFG ROXOR (like some people would try to make you think).

Yeah I'm using the component lead on the video card, but it is better than the ones with the wires sticking out of it. This one is a solid piece and the connectors are built in to it. I guess I'll try hooking it up to HDMI and see if there is a noticeable difference. This is just a 720p HDTV so I don't think it would be too noticeable.

It has a 1366x768 res, but games or the control panel never pick it up. It always says 720p is the highest. I was wondering if I hooked it up through the HDMI if it would allow that resolution? I had a hunch that that it might react differently since the drivers see it as a HDTV using the breakout cable and with the HDMI it might see it as a monitor? It's just a thought since I believe going through HDMI you don't have to set up all the TV related steps. I guess I might try it tomorrow and see.

The only real benefit to the component connection is to be able to connect to my TV and my CRT through the DVI connector for dualview.

whoa, thanks misfit.
