I am running windoew 7 Ultimate 64 bit with 8 GB memory and a Hanns G if 281 (28" monitor). Recommended resolution is 1920 X 1200 and that's what it's running. I am running an NVIDIA GeForce 9800 GT with dedicated memory of 512MB and shared memory 3583MB for a total of 4095Mb. The installed driver is dated 9/27/2009 provided by NVIDIA and is driver version 8.16.11.9107. I hope thats enough information. The monitor flickers all the time and any changes of the refrest rate form 50 to 60 or back makes no difference at all I used to think that the siae of the open window made a difference, but i don't think so any more. Please let me know what I can use to get rid of the flicker. I felt certain that a higher regresh rate will work, but I can't get one. Dan danhutch45@gmail.com

Is this a constant, steady flickering, like what you see with slow refresh and fluorescent lighting, or is is erratic, and causing the entire screen to blink out? I am also running a GeForce 9800 card, but my monitor is not as high res as yours. Found that while trying to run at the monitor native res (1600 x 1200 @ 60hz), there would be a lot of video noise that you could easily see with a black screen, and the whole display would erratically flicker out, but it was not a constant flickering as I believe you are describing. IMO, 50Hz is far too slow a refresh rate. 60Hz works for my display (Viewsonic VX2000), but 75Hz is better, but this monitor does not support it at higher res. I am not having any problems running at 1280 x 1024, but gave up on trying to run 1600 x 1200 with this monitor. If you have another monitor available, try that one. Also, try different resolutions and refresh rates. Fw

Hi Danhutch45, Please first download the newer display card driver from nVIDIA. Also, you can install the monitor driver from Hanns.G and then change the refresh rate to a higher setting. Note: If the driver is not for Windows 7, you can install it in the Compatibility mode.

Hope this helps. Regards, Linda
