3 Monitors - ATI eyefinity

[ZenixNet]

For a while I have been using 3 1600x900 displays, that works fine. Now I have upgrade to 3 1920x1080 displays and I have a problem. 2 displays work at 1920x1080 but the display-port display only works at 1440x900. I have a ATI certified display port adapter. My card is ATI Radeon HD 5770.

Are all 3 monitors the same make/model/resolution?
Have you installed drivers for each monitor? You can check in Device Manager in Control Panel.

get a different adapter.

2 are 21.5" HP LED same model, the other is a 25" HP led (same model as others, just different size) I have also installed the drivers.

Well, I bought a new adapter and it works. However, every time I reboot the resolution and placement of every monitor changes.

Try removing all but the main monitor, then uninstall them all in Device Mangler.

Reboot.

Add in one monitor (I'd suggest the Display Port one), let it be identified and installed, then reboot and see if the settings hold.

If you are still good with two monitors, add in the third one, let it be identified and installed, then reboot and see if the settings hold.

For what it's worth, my housemate experienced three-monitor weirdness with the latest ATI driver. (As of two weeks ago - they move pretty fast these days...) She never had any trouble before that.

I also have three monitors, and though I didn't have any trouble after I loaded the new video driver I did have to re-sort them all out after the first post-install reboot.

I have one more problem, after screen saver the middle monitor doesn't come on for a few seconds, the left (display port) says 'Input out of range' and I have to wait until the monitor goes to sleep then press a button on the monitor for it to come on. The right works fine.

Have you tried playing around with the Power settings in Control Panel?

What about the other problems, like the resolution changes - any luck there?

You might try a free 30-Day trial of DisplayFusion and see if it helps you sort this stuff out.

I havent had any luck. When I just have one monitor hooked up, its 1080p when it reaches the log in screen but quickly changes to 1600x900.
I think I'm just going to try a clean install. Something I have installed (or maybe ATI drivers are messed up, probably are) is doing something.

Have you done the part in bold?

Yep, the drivers have been installed.

After almost a year of problems with drivers, video card, and other stuff I decided to do a clean install. Hopefully this fresh slate wont get messed up like before.

It's a shame you have to do that, but I think you've made the right choice.

Sure hope so, I have spent the past 3 hours restoring files, installing programs, updates, and I am still far from done. I haven't had a chance to restart because of Windows Backup restoringso I have yet to see if this changes anything with my monitor set up.

 

[ZenixNet]

Just got done re-installing and re-setting up. All that work and.... nothing changed.
My monitors are still in the wrong configuration on reboot, the display port monitor still says "Input signal out of range" until I turn it off and on.
Could my card be bad? I have had issues with it for almost a year now (BSOD, screens turning green, settings change after every reboot, etc.)

 

[profdlp]

Do you have someone who could loan you an Eyefinity-capable card to try it out?

Nope :/

Is the card under warranty? After a year of putting up with this I'd exchange it if I could.

If it's not under warranty, would you definitely buy a new one if you knew the one you have now was bad? If that's the case I would buy one from a store with a money-back return policy and try it out. If the problem goes away, keep it. If not, you get your money back and head back to the ol' drawing board.

EDIT:

Sorry if I missed it, but are you sure your PSU is up to snuff? I don't know that it would cause this exact problem, but a card which is barely getting enough power might do all sorts of weird things.

I bought the computer through Best Buy so in order to get anything under warranty Freak Squad has to "fix" it first. Unless ATI has there own warranty, I don't have a warranty option.

I upgraded to a 750W PSU a few months ago thinking that was my problem, but it didn't change much. (The computer came with a 350W PSU, though the card requires 400W)

I have been considering buying a new higher model and better card. Any suggestions?

I'd go to ATI's website and check their RMA policy. Fortunately, I haven't had to return a video card, but most companies have you enter your part# and serial# and will tell you right away if it qualifies. Worth a shot.
