Hey guys I just bought a Pc from Cyberpower and here are my specs

CPU: Intel Core i5 35070K

PS:430 Watts

GFX Card: AMD Radeon 7700

OS: Windows 8

So the thing is I've used mutiple monitors and for some reason keep getting the same "Input signal out of range" error for all of them, but when I take out the card it displays perfectly normal. I've already taken out the card and have changed the resoulation to the lowest it could go and when I put the card back in it worked for about 10 sec and then I got the error message again. I cant think of anything else to do and was wondering if anyone at all could help me please

I've noticed Win8's Display/screen resolution and VECC don't always agree about what's happening with the displays.

And it sounds like you have onboard video also which may be helping to mess things up. Need specifics as per the sticky about what to post.

Yes I do have an Intel card on my motherboard. Every time I try use the monitor or my TV with the card hooked up it gives me the same "Input signal error" message

One last idea..

With one monitor connected to the onboard video, go into BIOS setup now take a look at page 48 of the mobo manual. These should be automatic but it doesn't hurt to be specific.

Change init display to PEG

Disable internal graphics

Save the settings and shutdown.

Connect one display to 7770 leave the other disconnected. If this works then the other can be connected to the 7770 too.

Restart

If it's still not working at this point then I'd give Cyberpower a call.

Sorry.. that's all I got.

By any chance do you think the monitor res. isnt high enough? Like would I need a better monitor with a higher res?

Don't know what monitors you have., and it's unlikely unless they're 640x480ish.

What did Cyberpower say?
