I have an issue with a new graphics card that I have bought today. My old graphics card, dual 8800 Ultra Superclock worked fine, but after uninstalling the drivers and installing the HD 6770 there was no sign of video. I also tried installing it on another computer that has an ATI onboard graphics but that still didn't work. If there is a solution out there, I would like to hear it! Thank you very much!
Do you use a monitor with a analog VGA (15-pin D-sub)connector?
if you do, perhaps your card's DVI is a DVI-D instead of DVI-I and your DVI to VGA adapter has nothing to forward from your pc to your monitor...
You could try installing your old card and then using Driver Sweeper. But be aware that sometimes Driver Sweeper can cause more issue. I've had to use Driver Sweeper is the past and it worked. Also, could try CCleaner.
I do use an analog VGA, I have two of the DVI to VGA adapters and both of them wouldn't work. I exchanged it for another one thinking that it was a defected card. But I also did some research, and since my board is a socket 939, couple people have been getting the same issue. So I'm not 100% if it is just the mobo compatibility or what not. My motherboard is an Asus A8n320-sli deluxe.
I'll have to try that solution out Rodney, hopefully it will work. I'll keep you posted.
Just an update marijanovic, I checked the dvi adapter is a dvi-d and the cards dvi is also dvi-d. My monitor is VGA and DVI-I but I have no adapter to the dvi-i.
EDIT: sorry I had dvi-d and dvi-i mixed up.
If you want to connect your monitor and graphic card using VGA you shoud connect the DVI-I to VGA adapter to the card's DVI-I.
It would be best to connect your monitor and card using only DVI. LCD monitors are digital and Analog-digital conversion causes a degradation of the image quality.
Did you update your motheboards bios? Try that first.
I'm just going to return it and get my money back, it was on sale anyways so I thought I would give it a go. But the tech I talked to said it could have been anything. I bought a DVI-I cable for the monitor to graphics and that didn't work nor did updating bios. But thank you for helping me out, I learned quite a few things about DVI-I, DVI-D, VGA cables =)
