View Full Version : Problem with my LCD screen

12-02-2009, 07:13 PM
I bought a 22 inch Acer LCD screen. I discovered it come with a cable for a DVI-D 24pin port. However, my computer doesn't have such a port. Darnit! I should've checked before I bought it. The colours on my screen are now that like when you start Windows in safe mode. Is it cause that DVI cable isn't plugged in? will I need to buy a better graphics card that has that port? I currently have a GeForce 61000 nForce 400. I'm hoping a few settings I gotta fine tune, drivers perhaps, and I'm sussed, but I fear the worst. :(
So give it to me...

It should run ok on just the VGA cable.
You will have to bring the resolution up to most likely the maximum your card will allow.
I think the native resolution for a 22'' wide screen is 1680x1050
If your drivers are up to date you should manage that.

Buy a DVI to VGA adaptor. http://www.dse.co.nz/dse.shop/4993ebc100b2fa982740c0a87f3b0755/Product/View/XH6788

Driftwood is correct ... it will probably run at a screen refresh rate of 60 Hertz. My Viewsonic 22in runs at 1680 x 1050 x 60Hz which is the native resolution for this monitor, I think yours will be the same. Use 32bit colour resolution, it sounds like you are running in 256 colour mode at the moment. BTW, you won't get the clearest display with the VGA analog connection, DVI interface definitely is an improvement.

Thanks for the helpful tips. With that adaptor I soon hope to enjoy the full experience of my new screen.

I don't think the DVI to VGA adapter mentioned by Trev will improve the picture you now have. You already have the VGA output from your current graphics card connected to the VGA input on the monitor, correct? You should be able to get it to run at 1680 x 1050 x 32bit colour quality (or maybe 16bit colour quality). This will be the best you can do with the VGA output.

You will need to replace the current graphics card with one that has a DVI output port to take advantage of the digital improvement. Mine (NVidia 7600GS) has both VGA and DVI outputs. I have two PC's connected to the monitor, new PC uses the DVI interface and the old PC uses the VGA interface. When I switch between the two the difference is quite noticeable. The text in the VGA mode is nowhere near as nice as the DVI text.
