Question about Dell M781S Monitor

1 Answer

Horizontal ghost lines across screen

I have a Dell M781s monitor and it has started having ghost-like horizontal lines across the screen. They occur behind any and all letters and span across the whole screen. I've tried another monitor and the same thing happens. Any suggestions? Could it be the video card is bad? Thanks!

Seems that it is an issue with your video card, Please update Driver for Video card and it that does not help, it is the time to replace the Video card.

You can get your driver from support.dell.com and please enter your service tag to download the driver

My Dell monitor developed a thin, dark line horizontally across the screen. Within three months, a second line appeared. I can view the screen, but must look above or below the lines at times. Any idea...


this occurs very commonly in all LCD monitors... this is because each and every cells in the LCD monitor are energized by the vertical and horizontal electric fields placed around the frame of the monitor... if a particular field does not gives the power to the associated cells to it, then the entire line of cells will not operate and together they looks like a single line...This is what happened in your case...

Do you have the monitor plugged into a power strip. If so unplug it and plug it directly into the wall.

Shadow Lines Across Screen on Dell P1130 CRT Monitor


What sort of shadow lines? I assume you haven't just noticed the two horizontal lines 1/3rd up the screen from the bottom and 1/3rd down from the top from the internal stabilizing wires that all Trinitron CRTs have?

Horizontal lines on Screen


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Brown horizontal lines sporadically appearing on monitor


I had the same problem. I fixed it completely today. The horizontal lines disappeared. IT IS DEFINETLY THE DEVICE DRIVER. I confirmed my monitor model tyope (dell M783s) and downloaded the specific driver for this monitor.

I had to do these exact steps or did not work.
1) with the problem screen, disabled the display adapter under the Hardware/Device Manager settings.
2) Restart the PC
3) Boot will come up with brown lines still but the screen will low resolution of 600x800.
4) Then I installed the correct device display monitor driver onto the pc. ( you may need to scan for new hardware, then choose the directory with the new hard drive.)

If you need step by step... just reply back.

Thin pale Horizontal line


I tried this and it has worked temporarily by banging the monitor not great but it did work, no tech knowledge if there is any other advise please email.





Hiyama Monitor Model: Vision Master 17 (8617E Chassis)
Horizontal dark line across screen shadowing text or other complex display data - giving appearance of 3D grooves or just dark lines on light background - temp fix (few minutes) by banging monitor or jiggling the video cable (thats what threw me for a while)
Removed tube base board and ran over disc capacitors and other solder joints whether they looked dry or not. No re-occurence in 2 weeks of daily use. Seems to have fixed it. (Be prepared for a lot of metalwork and screw removal when opening one of these up - I still havn't figured out how to get the PSU/main board out of one !)
