Poor Image Quality With DVI-VGA converter Options

Hello guys, i just bought two new 22" 1680x1050 resolution ASUS LCD
screens (vw222s). They only have VGA inputs, no dvi. I use an NVIDIA
8600GT 1gb graphics card with the latest drivers. Running vista 64bit.

The graphics card has 2 outputs, a VGA and a DVI. The problem i have
is with the DVI output. I use a dvi-vga converter to connect to my VGA
input on my new screen. The image quality is A LOT less sharp than the
straight VGA output from my graphics card to the VGA input of my new
screens. Also the dvi-vga connected monitor producess small errors
here and there.


I have already tried a second similar DVI-VGA converter, but both give
the same bad results :( Because i have two screens next to each other,
and both using different outputs of the GPU i really notice the
difference. Before i had two 19" LG's, and with those screens i never
noticed any difference.


What could cause this, and how can i resolve this?


I hope you guys can help.


Thanks very much!

If you switch the screens over do the problems move to the other screen?

If the only thing you've changed are the monitors then I'd suspect them of being problematic - you haven't exactly got an obscure card so there shouldn't be compatibility issues.

Do you still have the old monitors? If you put one of them on straight VGA does it still look better than the new monitor?

Are you using the same cables...

Try all possible configurations to narrow the problem down to the exact componant

If at all possible... it would be worth trying a DVI - VGA cable, as opposed to an adapter.

I've always found that 'dongles' tend to dangle :D
By that I mean... unless you can jam the cable against a wall, so the adapter/dongle remains securely attached to the DVI port... the weight of the cable hanging from the adapter/dongle, tends to pull it downwards/make it droop.
This can result in a bad connection, or bent pins.

Using a genuine DVI - VGA cable, helps alleviate that problem, since it rules out the need of a dongle, such that it doesn't stick out as far from the DVI port, and is less likely to dangle... like the dongle :P




If you understood all that, then you're a better man than I Gungadin!
