Edit 3: I know what the problem is now, but I'll leave the original text, in case other users can benefit from it. I have also tried a variety of fixes, before I found out that the problem was ATI's drivers.
To summarize:
Nvidia users have no problems. They have no distortion and they can use 60, 75, 85, 100, 110 and 120hz in all resolutions.
ATI users have problems with distortion in 2D mode, and some also in 3D mode with certain gfx settings. Quakelive here being a fine example. A few users have success in both 2D and 3D mode. ATI users are also stuck with 120hz in native resolution in Windows 7, while it works in XP.
The ways to fix it is either:
- Change to an Nvidia card
- Run with two monitors attached
- Increase 2D clock rate
- Use 60hz on the desktop.
The distortion problem can be seen here. Sorry about the sound but I couldn't find a way to remove audio on youtube.

Hi, I just changed from CRT to the new 2233rz. The problem is that 120hz only works on the desktop, if I'm doing nothing. If I double click on an icon, open the calender or perform just about any action and the screen starts to blink. I've tried various solutions and many different drivers but to no luck. To the users that have a 2233RZ, VX2265 or 2268 screen, do you experience any problems like this or know what the problem could be?
My system is the following:
E7300
Sapphire HD4830
Sea Sonic S12II-500 watt. (So I'm positive I've enough watt and amp)
Windows 7 X64
I have googled for ages now and tried a variety of fixes.
- Changed the power cable since apparently it helped two users with a similar problem, granted they had regular 60hz screens.
- Under- and overclocked my ATI hard, since that helped a lot of people with similar problems, though they had also 60hz screens.
- Forced the graphic card fan to run at 100% to eliminate heat as a problem, even though it's always at 39 degrees in idle.
- Changed port on the graphic card.
- Checked I really had a dual-link cable.
- Tried the "alternate DVI operational mode" and "reduce DVI frequency..." settings.
- Enabled LCD overdrive and tried all possibilities here.
- Installed the 2233rz driver on the Samsung website and the one on the CD.
- Reinstalled Windows and tried Catalyst 9.7, 9.8, 9.10, 9.11, 9.12. No luck what so ever.
It's visible both in-game and on the desktop. I'm beginning to believe it's a problem with the ATI HDxxxx cards or drivers, from the threads on the ATI forum.
I've mailed Sapphires support, since Powercolor cards seemed prone to produce the problem on regular 60hz lcd screens. A new BIOS was released by Powercolor that supposedly fixed it.
Edit:
I got it working. I don't know who I should blame the most, Microsoft, Samsung or ATI, but ATIs GPU scaling isn't working that great in Windows 7. I got it re-enabled and enabled LCD overdrive as well, and now the screen works perfectly in 120hz! Sadly I can't use 120hz in other resolutions but at least I got a smooth picture now.
The fix is the following:
- Set your resolution to anything below your usual resolution.
- Hit the CCC
- Top left, click "Graphics", and "Desktops & Displays" on the pulldown menu.
- For your desired display, click the little black triangle in the bottom part of the screen, on the LITTLE picture, not the BIG one, and click "Configure".
- The scaling options will now be selectable, check the "Enable GPU scaling" box and select "Maintain aspect ratio".
- Change the resolution to 1680x1050 and 120hz, but NOT with CCC but instead use Windows. If you use CCC, you can't go back to GPU scaling.
- Enable LCD overdrive and adjust the slider. At first I selected 110 and then the jittering disappeared. Then I turned it back to 100 for kicks, and it still worked.
- Even though the before mentioned scaling controls are greyed out and you can actually see "Scale image to full panel size" grey-selected, don't worry.
- Go play your games!
Edit 2:
Looks like I celebrated a bit too early. As soon as the LCD overdrive window was removed, the blinking started to come back. I opened LCD overdrive again and the picture was perfect again...it seemed. From time to time it would show a slight blinking but it wasn't a lot. But even with LCD overdrive running in the background, it's not possible to play. At least I think I've found the culprit or one of the major reasons at least. Now ATI just need to fix it.
