ATI HD5770 Problem With Acer 23" Monitor

[Saidar]

Hello,

I got my new graphics card yesterday, an HD 5770. My previous card was a HD4870.

I did not upgrade, my card's fan failed so they sent me a new card, but to my surprise it was a new model, but that is a story for another thread.

So happy as I am I installed the new card and behold, I cannot run my screen at 1920*1080. Don't know how to describe this but my screen is smaller, and centered.

It is like watching a movie with dimensions that your screen does not support, a black strip is present at the top and bottom of the screen. Only in my case the black strips are top bottom left and right.

Currently I'm running my screen at 1440*900, the only resolution where my screen is displayed "full screen".

If you don't understand ask me and I'll try to explain better, I will even take a photo and post it.

What can be the problem? Do I have to get a new monitor or what?

Thanks!

Saidar, welcome to the forums.

First thing to ask, did you remember to uninstall the video driver and CCC before installing the new card, and then install the driver again?

Hey,

Yes I did, uninstalled all ATI software before installing new drivers. Maybe I should uninstall restart and try again?

Ok it is not a driver issue, in fact when my PC boots up, before loading windows the same effect is present, with black strips on all 4 sides of my screen.

Maybe I should buy an HDMI cable, can the type of connection cause a problem like this?

Not sure why you would want too. Unless your monitor is different from either of these,

Newegg.com - Computer Parts, PC Components, Laptop Computers, Digital Cameras and more!

as neither has a HDMI port. How is it connected now, VGA or DVI? Also does it show up as an Acer in Device Manager or is it showing as either "plug and play monitor" or "non-plug and play monitor?

I'm using an HDMI to DVI cable at the moment. That is why I thought maybe a HDMI to HDMI would work better, as the new graphics card has an HDMI port.

My monitor is showing up as Acer V233H

Try it with just a plain old DVI cable. Also,

not going to work unless the monitor has a HDMI port as well, and from what I can see your monitor doesn't.

My monitor does have an HDMI port

Use an HDMI cable that is Version 1.3a at a minimum and install the latest Catalyst drivers. Uninstall the old drivers first via the installer, then reboot and use Driver Sweeper to clean up, then rerun the installer. Finally, force the right resolution in desktops and displays.

Thanks, any idea how to "force" resolutions?

its a scaling thing - go to ccc, then graphics tab , then go to desktops & displays , then go to bottom of page & right click the picture of the screen you want to adjust then select configure , then make sure enable gpu scaling is NOT ticked , then select scaling options at the top of page - here you will find a slider with underscan & overscan - drag it to the right (overscan) this will solve the problem - some monitors / hdtvs force there own scaling - this option is a good workaround by ati & will still give you a perfect 1.1 pixel ratio

Awesome thanks! It worked!

You saved me a lot of effort, I really do appreciate it

Glad to help - catalyst can be a bit awkward to find stuff but its all in there - its why i switched from nvidia to ati (nvidia control panel is bad) plus i find that the video output is generally sharper than nvidia as well
