Try another monitor.  If that doesn't work reinstall your video drivers with control panel system device manager.

The brightness and sound indicator appear automatically(without pressing any buttons on the screen) on the screen and there is nothing that takes it away.


have you tried pressing the escape button on your keyboard
there are a number of things you could do to correct your problem
click start control panel administrive tools computer management device manager scoll to ports(com&lpt)right click to scan for hardware changes or scroll to monitors + to expand plug and play monitor right click where you have options to update driver,disable.uninstall,scan for hardware changes or select properties where in the general you have the option to troubleshoot also in the driver tab you have the same options as when you first right click on monitor
also
click start control panel,display,desktop you can select a different desktop from the drop down list also settings you can change the settings for more or less pixels or from the drop down list pick the appropriate level of color range or troubleshoot also select advanced then general dpi normal size,larger size or custom settings
always click APPLY after making any changes
another thing you could try scroll to the bottom toolbar (bottom of screen) right click you can select task manager applications if you see anything running that you dont want or need select end now

and another
During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
or
During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer

Black Screen when playing 3D games on ATI Radeon 9550 X1050 Serie


the game resolution is not supported by your monitor....this is the reason your screen goes blank....
by the next time if the screen goes blank, press alt+ctrl+del together and check are you able to see the task manager....
if you can see the task manager, then close the game from that window by selecting end task....
if you cant see the task manager, then press ctrl+alt+del together 2 times and check....
if nothing works, then try by checking with any HD monitors if available with you or with your friends...

Monitor keeps hibernating, can't make it stop, pixel issue.


Hey,

I think this is more of a problem on your computer instead of the monitor, ofcourse you could try another monitor and see if the same happens. I suspect your computer goes into standby or hibernation on its own, and it does work fine if you reset the computer right?

if you go into power management again, disable or turn off hibernation completely, its on one of the pages.
Make sure its not set to standby, and also disable your screen saver.

Right click on desktop - properties - then screensaver. turn it to none.

Also you could look into the computer bios and make sure its not set to standby or hibernation from there. thats unlikely but you could check.

how to get into bios.. depends on the computer, right when you turn it on, on one of the corners of the screen you will get a message, press button to enter setup or bios. press that to enter bios when its presented.

look around the bios and poweroptions.


Let me know if you need anything else.


Thanks,
Ekse

Al 1916 problem


really? here's the thing..try to check the display settings manually.press the menu button of your monitor then try adjust the contrast, brightness and colors as well to your desired level..if your'e using LCD monitors, these are very sensitive and can be easily damaged if don't handle it very well..don't press the auto button always because it will automatically adjust the settings every now and then..
