I recently migrated from an 8500gt to a hd4550. The problem is that with the new one my display is somehow smaller, like my 24" monitor became a 22" monitor. It has a black "belt" around it, and not just in windows, it's like that right when i power on the pc, even in bios. If I plug in the old card, everything is fine, with the "new" "belt" around. See pictures attached:

Did you completely remove the 8500GT's drivers before installing the 4550 ?
If you didn't,then here is how
1_Download and install "Driver sweeper" from and install
2_Go to add/remove programs and uninstall the driver and reboot
3_Boot to safe mode and open driver sweeper,then click on Nvidia and then click on clean
4_Reboot and boot normally to windows and install the new drivers after that you need to restart,and its done

I uninstalled the drivers first by doing: right click my computer, properties->device manager->right click the display adapter (8500gt) ->uninstall
Then reboot, change the video card, start windows normally (windows 7 automatically installs drivers for the new device hd4550) and install the ati drivers.
Monitor: hanns g 24" full hd, 1920x1080 native resolution. Changing the resolution doesn't help.

Try the way i mentioned, and download the latest drivers from AMD's website not with windows update.

it's like my 24" became a 22", no matter the resolution or driver. My computer just starts like this, right from the boot time.

Right click on desktop>screen resolution>Advanced settings>Adapter>List all models
And choose the last one from this list and see if you still get blank spaces or not

hmm,its really strange.Perform a clean install of Windows and see if it still exists.
Also can you test it in another system ?

on another system it's fine. Is it possible for it not to able to work with my 24" display?

Can you stretch the display to fit all the screen with the buttons on the monitor itself (like on the old CRTs)?

Is there not an "Auto Adjust" feature on the monitor itself?
September 20, 2010 6:31:53 PM

I didn't say it wouldn't display. I said for a 24" monitor I would recommend at least a 5750. Please pay attention.

i got the point, but there are no founds for 5750 :) 
anyway, this is strange, my "Auto adjust" function from the monitor is Off and non-adjustable.

If the auto adjust function isn't working try messing around with the settings like "wide" & "aspect" or something similar. Also try switching up your input connectors. I had this issue once with a LG monitor and switching it from HDMI, DVI, and VGA seemed to cause it to auto adjust somehow (I forgot which one fixed it).

my monitor only has hdmi, which I connect to the video board by dvi (hdmi-dvi cable). I fought of this too, but I don't have a hdmi cable:) 
Anyway, i remained to may old board, 8500gt, I gave up:)

It is a problem I also encountered with a Sapphire Radeon HD 4550 after changing from a GT 7600.
Driving a Hanns G 24'' Monitor via HDMI. The graphics card will naturally underscan when you install it... so you have a black border all around, while screen resolution is given as 1920 x 1080.. Graphic card gives out right resolution, but then underscans it as it is thinking it is going towards a TV (really funky in the days of LCD TV's)

Download latest drivers, Install CCC
Start CCC
Look under My Digital Flat Panels.. in newer CCC... Select Scanning Options (or so...)
Right Click on My Monitor in older CCC select customize or options

Select the Overscan, Underscan tab.. look at the slider. (it probably stands in the middle... counterintuitive where it says overscan is the regular resolution) . .it says Underscan to left and Overscan on the right... pull the slider all the way to the right.. underneath 0 (Zero) Your screen moves to full monitor size...

Thanks a lot, but I sold that video card mean while and bought a 8800 gt :) 
Good to know anyway and thanks for sharing!
