Samsung 204B LCD screen blackout
After re-installing SP3 on my XP box while trying to figure out a software issue I found that I lost my previously set NVIDIA timings which were set to stop the monitor's random screen blackout's. So rather than dredge through the forum's again next time, let's face it there will be a next time with MS, I thought I'd note down how to do this for future posterity and my sanity.
The screen blackout issue with my Samsung SyncMaster 204B occurs when using the DVI input on the monitor. The screen will blackout at random times and then flick back on, this does not occur when using the analogue input into the monitor. This issue only happen's on some Samsung 204B monitor's.
Open the NVIDIA control panel, select Display, then under the Appearance menus select "Manage Custom timings". Select the Create button, select the Advance button on the "Custom Timings" dialog and set the timing standards to "CVT reduced blank".
