Problems in displaying 1920x1080 resolution on a 21.5" monitor

mouS3 · May 27, 2011, 06:21 AM

I have a problem with display resolution on my monitor BX2231 - LED Monitor - Monitor | Samsung

Until recently I had a Radeon HD 3870 set to 1920x1080, and I recently bought a Radeon HD 6870 that I wanted to keep at the same resolution. Unfortunately I encountered the following problem. When I set this resolution my image is displayed on the middle of the screen with a black border around the edge (not covered in full screen image). Widows tells me that the resolution is 1920x1080 and the monitor supports this resolution. The old board did not have that problem plus the phenomenon it is also manifesting in other resolutions, but not all. The monitor has been linked in both cases with DVI-HDMI cable, but works the same on HDMI-HDMI.

Can someone enlighten me which is the problem?

I reinstalled drivers, windows and all for nothing. The image doesn't go full screen only when upscaling it from Catalyst Control Center.

I had a similar problem with an old TV of mine. There is a setting in CCC (not sure where off-hand as I don't have CCC on any of my PCs) that is I think under screen settings or resolution. It's two check boxes, one for V-sync, the other for H-sync. It's been years since I've done it but if it's not one, the other should do it. That should sort the problem.

I was having troubles getting my monitor (native res 1680x1050) to display 1400x900. It wouldn't cover the full screen.

I went to CCC, My VGA Displays, Image Adjustment, and clicked on the yellow triangle on the top bar. That made it expand to cover the entire display.

I still had problems though. With IE open, it would 'shake' when I changed pages. It was at 1440x900 @60Hz. I changed the refresh rate to 59Hz and it's rock solid now.

None of these options are present in CCC 11.5. Anyway there is an option under HDPanels menu where you can upscale or downscale your image. With that option I can make the image to cover the entire screen.

Anyway I don't know if it is normal to do that or if there is a problem with my video card or windows drivers?!

Sorry if it's unneccessary, but have you tried the auto adjust button on the monitor, it's sometimes needed after changing the graphics card?

ATI has always had and continues to have issues with DVI to HDMI or HDMI/HDMI connections... it's a royal pain in the ass... and their setting system to "expand the image to fill screen" by manually increasing the size to fit is a total load of crap..

If there is a case in which nvidia does a whole hell of a lot better but not perfect, it's HDMI connections.

with Nvidia, it actually allows you to do it pixel by pixel in all 4 directions.... but no ati.. no no.... and they don't allow either hte pixel by pixel adjustment, and they certainly don't give the option for any specific direction.... it's like the most horrible setup yet and pisses me off.

I'd suggest if you can, connect straight through DVI-DVI..

HDMI ~> DVI however is no issue and never had a problem even with 2048x1152... but DVI ~> HDMI or HDMI ~> HDMI.... pain in the ass with many tvs.

Another option, if you have an input select on that monitor, allowing you to "name" each input, set the HDMI input name to PC and see if that helps.

I'm using 11.5 and it IS there:

It is a "normal" problem with how the driver identifies some screens as TV sets, or identifies some TV sets as needing this setting when they do not. It's a HDMI "intelligence" thingie. Updating the monitor driver might perhaps help.

You might have that option OldBuzzard but my CCC looks like in the attached file. I can obtain a full screen image just by dragging scaling to maximum overscan.

@mkk
I have the lastest drivers Catalyst 11.5b and the only monitor drivers that exists for my LED. Because they made just a single version of drivers.
In my searches over the internet I read somewhere that Windows doesn't detect well 75% of LCD and LED monitors sold in the world. I don't know if it's true but that might be the problem.

Anyway I went to a friend and put my monitor on his Radeon HD 4870 and it looks the same. I can't understand why on my old 3870 was no need for overscaling

I think that your CCC looks different because your monitor uses a different kind of connector. That said, I have a suggestion, can you try connecting your monitor with just a VGA cable? I know it sounds kind of dumb to use that with all the new and advanced connectors, but I'd just try it and see the image quality I'd get (if necessary, use the Auto button on your monitor to correct screen position and signal frequency).

Judas · May 28, 2011, 04:25 PM

Oldbuzzard and mous3 both get different things because of the different connection and detection schemes ati uses to identify the monitor.

Pure HDMI gives what oldbuzzard gets.

Most HDMI connected monitors however get what mouS3 has gotten.

Some HDTVs work differently...

All i know is ATI's solution even with the oldbuzzards screenshot options... are total shit

I tried today and I got the same menu as OldBuzzard, but there was no need to do anything because the image was covering all the screen.
Anyway I'm not satisfied with this solution. After all I didn't buy a FullHD LED and a good graphic card to use an analog signal.

IvanV · May 29, 2011, 11:18 AM

I hear you, man. Still, you are getting the FullHD resolution and all the benefits of LED backlight and on a card with a quality analog output there shouldn't be much of a difference compared to what DVI or HDMI connection would give.
