Hi,
At times, this might be because of a Video Driver issue also. So, to rectify it, One simple way, is to check it with another monitor if you have one. Connect the Tower(CPU) to the other monitor & check if the display is fine. If not, then its is a problem with the Video Driver & you r monitor is working fine. But if the display is fine on the other monitor, i'm afraid to say that your monitor might have gone bad. you can probably take it to a hardware repair shop nearby.
Hope this was helpful.
Cheers, Have a nice day!!

LCD monitor have Vertical lines and black colour become greenish


normally the 19" resolution can support up to 1280*1024, but if it comes with vertical lines in full screen, it might indicate the panel is no longer to work and probably it's time to replace new one.

Vertical lines in my laptop screen


Try connecting an external monitor to the Dell Inspiron 9300 and see if the vertical line is also present on the monitor. If the monitor display is fine, then your laptop’s LCD display panel is defective. If the monitor also displays the vertical line, then your problem is with either the video card or motherboard located inside your laptop.
Not sure if the Compaq Presario has an external monitor plug, but if it does the above procedure can be applied to that one as well.

Red Vertical lines on 15" Acer LCD Monitor


I think this is most likely a monitor problem. Can you try a different monitor of computer to the monitor? That would help pinpoint the problem. Is it under warranty?

Thin red vertical line length of screen(right side)


Your Display cable (inside your monitor) needs to be replaced.

I would look on ebay to try and find the part and then take it to a local tech to replace it for you as I would not recommend anyone take apart a monitor (LCD OR CRT) if you had never done so before.

OR, Buy a new monitor.
