Problem with the P5VDC-MX to display 1680x1050 resolution

Bought a new SamSung 226BW monitor but when I changed the resolution setting to 1680x1050...screen just flickered and jittered like crazy. Frequency is set to 60Hz(recommended) but I also tried different luck.

Already updated Bios(version 0805 ofr P4M800 Pro dated Jun 20 2007), also updated the S3 Unichrome Pro IGP driver from its website....also updated Samsung latest driver...still same problem.

Monitor screen goes blank often.we r havins asus motherboard P5VDC-MX P4M800 PRO CHIPSETSUPPORT.

It may be that your display resolution is set for a resolution not supported by your monitor. Since you did not specify the type of monitor or operating system I suggest that you go to Control Panel and select Display or Personalization and set your resolution to something like 1024 x 768 60 hz and see if you have the same problem. If the problem has disappeared then select a resolution compatible with your monitor.

If i try to connect to 1680x1050, my screen goes dark. but when im using 1600x1000 it still desplays

The resolution 1680X1050 is the native resolution for your monitor. This means that the best view for your monitor is for this resolution. Your problem in not at the resolution, it's at the refresh rate. How to fix this? Go to the settings for your screen. At the lower right corner you will locate "for advanced users" button. Click on it and choose the "screen" tab. At the lower part of the window you will locate the "refresh rate". Click on it and change it at the lower setting (about 60 - 70 Hertz). Click on aplly - OK. You will be back to the resolution settings page. Set the resolution at 1680X1050, apply - ok. Go back to "refresh rate" window and change the setting to a higher setting STEP BY STEP. In case of an "out of range" and blaack screen DON'T DO ANYTHING, at 15 seconds you will come back to the previous settings. With this procedure you will get the native resolution for your screen with the higher refresh rate.

New monitor but unable to use its maximum resolution settings

no, there's nothing wrong with either your graphics card & monitor.. it just that your graphics card does not support a 1680x1050 resolution. if you want to fully enjoy the resolution of your monitor, you should upgrade your graphics card. purchase at least 256mb graphics card and you will see the difference..

You could check your DPI setting in the display, being a large monitor your DPI setting shoul be up around the 75 - 85 Hertz.
To access this
Control Panel --> Display --> Settings --> Advanced --> Monitor and then click the drop down box and see what the DPI is set to and keep trying the different options until it is clear.
Hope this helps.

Movie on monitor

Hi, Normally I would suggest that you first lower your laptop's screen resolution, refresh rate and color quality and verify that you have enabled the external monitor or dual view in your Display Property Settings as well as the Fn key + F?. However, this kind of problem should not exist with an LCD Widescreen monitor with specs and features as your Samsung 226BW. If trying the reco on the first paragraph and you still have no movie display (but all other laptop display shows), perhaps it is a problem with the Samsung 226BW. To my knowledge, this particular brand/model uses no less than 3 different panel display, some not as good as the others. Verify that you have an original Samsung panel display in your Samsung monitor by looking at the sticker at the back of the screen, it should say Model: 226BW [R] S. If it says A or even a C, then perhaps the display panel is not living to its specs/claimed capacities. You of course can request a replacement from your dealer and cite your problem but insist that it be an "S". Most instances (but not always) an "S" would mean panel screen by Samsung, "A" by AU Optronics and "C" by CMO. Hope this be of some help/idea. Pls post back how things turned up or should you need further information. Good luck and kind regards.
