Boot from safe mode and try a different pixel/color arrangement. Obviously a lower pixel and color setting.

I have no blue light at the power button for my Synchmaster 225BW


The power switch is a momentary tactile switch. If you want to fix it, you will have to turn it off and look at the size of the switch to try to find the replacement for it. Not much you can do but open it up to find the cause of the problem.

I have completely black screen, and the powerlight stays blinking, can't shut it off


First place to check will be the power supply section, look for caps with bulging top, post back what you see so we can guide you further, see example of failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

This model was released in 2001, you need to open it up and look for bad caps with bulging top first, the problem can also be in the backlight inverter circuits.

I am using Ubuntu 9.10 in a dual-boot config with XP. I have a Samsung Synchmaster 931B monitor in analog mode. Works fine and drivers installed under XP, but will not support extended effects under...


it's your graphics card not the monitor that often has proprietary drivers to drive compiz and other effects.

If this is not a laptop, then it is easy to interchange.

Nvidia is one such vendor that supplies special drivers for Ubuntu

Black screen with power switch flashing blue.


I have been same problem but in other type syncMaster, the solution is open your LCD monitor look for power supply module (PCB which have connector to AC power), on that PCB look for capacitor , for normal condition its look like small tube. now look for broken one which upper part is bloated.

I hit a button on the bottom of my monitor and now my screen is black and the light is flashing blue? what do i do


I have had the same problem with two of these monitors. If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.
