With my new Samsung Syncmaster BX2450 I have the following problem:

In Windows XP (SP2), all resolutions above 1440x900 have either strange pixel errors or an extreme flickering. It seems, that the effect worsens for higher resolutions. In special, I would like to run the monitor with its native resolution (1920x1080), however I can't watch longer than 5 seconds on the monitor because of the flickering...

My Graphics Card is a Geforce FX 5200 with the most up-to-date driver (according to Nvidia.com: Forceware 175.19) and I'm having the monitor connected to its DVI-output.

The strange thing is, under Ubuntu 10.04, all resolutions work just perfect, so the display must be alright.

edit: seems to be a driver problem... if I use the proprietary NVIDIA drivers in Ubuntu, I have the same problem as in Windows.

I would like to reformulate my question:

Is there a modified/alternative Geforce FX 5200 driver (as there is in Ubuntu) for Windows that allows me to use 1920x1020 without problems ? I already tried the omega drivers: unfortunately, it still looks poor on the native resolution.


According to Samsung, the BX2450 has the native resolution of 1920x1080.

With any higher resolution, what you are seeing is only interpolation. So evidently, the Linux driver does it better.

I would suggest staying at 1920x1080. As regarding flickering, you might have a look at the refresh rate.

  • My problem is that every resolution ABOVE 1440x900 (which of course includes the native resolution 1920x1020, which is also the maximal resolution i tried) shows flickering. I didn't (and won't) try any resolution above the native resolution. – ptikobj Feb 12 '11 at 12:15
  • Above or below the native resolution means interpolation. What is the refresh rate? – harrymc Feb 12 '11 at 12:32
  • The refresh rate is 60Hz, as recommended (I can't change it anyway). – ptikobj Feb 12 '11 at 12:43
  • You have done all that is in your power to do, and the monitor is probably defective in a way that only shows in Windows. You may try to use the warranty, or if in Windows 7 degrade the display (turn off Aero). – harrymc Feb 12 '11 at 12:54
  • The problem seems to be that the FX 5200 supports DVI-resolutions only up to 1600x1200 (which, after another driver update, I can confirm: up until 1600x1200 the picture is kind of alright, but the native solution is still messed up). source: nvidia.com/page/pg_20040109440047.html – ptikobj Feb 12 '11 at 13:59

You could go to "Change Resolution" from the Nvidia control panel.

  • How does it answer the question? – bytebuster Nov 6 '12 at 5:18
