There are so many thousand of TV types out there that a general question like your just can not be answered without more information from you.

Restart ur computer and get into the BIOS. check if the line is there also. then plug in an external monitor into the VA connector of the system and check if the line appears there also.

If in both the cases, there is a line, then the problem is with the video card. if the line is only seen on the notebook display, then the problem is with the built-in screen, which means you will need to get the screen replaced, or get a new monitor. Check ur warranties.

If the video card is found to be the problem, then depepnding on the video card (on-board or extendible) it will need to be replaced. Again, check ur warranties for any free service.

open the monitor there is a movable preset attached to EHT rotate that preset by screwdriver in active on condition of monitor reduce the brightness to satisfactory level

Both are signs of a worn out tube. The only thing you can do (apart buying a new monitor) is to increase the focus and acceleration tensions on the tube - by tweaking the corresponding semiadjustable resistors.

Adjust contract and luminosity: decrease contrast, see how it goes.
ACER monitors tend to have control settings that are out of the range for proper viewing.

Sounds like a CRT problem but to be sure, hook up another monitor to the computer and if you get the same exact lines then you know its a problem with the video card, if the lines go away then you know its a problem with the monitor.

so is your screen like fading to black and back to bright when u do something? If it fading in and out try adjusting the monitor settings on the monitor itself. Whats happening is your monitor is trying to save energy so it dims. The setting is Luminance on most monitors

And by the way u cant reach a video capacity cause the memory dumps the info when it needs space to process more video.

replace the monitor: it's lost vertical scanning

Please try and external monitor if the picture is OK then you are having LCD problems. I dont know for you but over in the States here: http://lcdrepair.net They maybe, are able to help you.

I don't know for sure if this will help but it's worth a try. Go to Start, control pannel, system, advanced, performance, settings, and click adjust for best performance. This is a Windows XP fix but the same thing may apply to older OS's (95, 98, 2000, ME, NT (although you may have to set it a diferent way). Many other things could be your problem but this is an easy thing to try.
