Note: a monitor may or may not have these capabilities. Sometimes they are undocumented and not described in the user's manual. <br /> <br /> <br /> For example, a Planar monitor I have, has a self-test that isn't in the manual. <br /> It is activated like this:<br /> <br /> Power-up the monitor<br /> <br /> Simultaneously press the <br /> Left OSD adjust control button (1st from leftmost position)<br /> Right OSD function select button (4th from leftmost position)<br /> <br /> The display enters into a continuous loop displaying <br /> All<br /> white screen<br /> black screen<br /> red screen<br /> green screen<br /> blue screen<br /> <br /> That simple test lets me check for stuck or damaged pixels, improper driver scanning of the screen (so I can blame or rule-out video card signal and memory when &quot;funny patterns&quot;, stripes, dots, sync problems, etc) are displayed, and problems that might be over-heating related.<br /> <br /> <br /> You can &quot;play&quot; with various combinations and sequences of the buttons to see if you have simliar undocumented features. <b>Sometimes a self-test button sequence has to be pressed at the same time you press the power-on button.</b> text/html 2008-04-18T16:08:14-05:00 MrBungle http://www.hardwareanalysis.com/content/topic/71315/#533945 if you set your video mode to something conservative does the problem go away?<br /> <br /> try 1024x768 at 60 Hz text/html 2008-04-18T12:56:03-05:00 Briahna Cochran http://www.hardwareanalysis.com/content/topic/71315/#0 one morning i woke up and my computer monitor was screen was shifted to the right and it was dark.<br /> when i pushed the menu button on the monitor to change it it flickers on for a minute and then goes away. <br /> its really bugging me!<br /> any help?
