Hi, my monitor seems to have developed a fault. The display is jumbled and halfway across there is a vertical lie and the text is stretched to the rhs of the screen! This only happens when the res is set to 1024x768, if i change the resolution to any other it looks ok on the screen. is this a graphics card fault do you think? The monitor is a 17in lcd widescreen, i also use it for t.v. which works fine still.

This is how the screen appears.

As has already fitted a different video card and a second monitor works (as noted by and ), the balance of evidence points away from the PC and toward the LCD — most likely the monitor's scaler or the PC-input path for that specific mode. Widescreen panels need to scale 4:3 modes like 1024x768; if the scaler, analog input timing (clock/phase) or cable is marginal the image can split, stretch or lose text while other modes and the TV input remain fine.

Quick, practical troubleshooting to isolate cause and possibly fix it:

  • Check the monitor's native resolution and recommended refresh rate in the manual or on the back label. Native modes never need scaling and are the baseline for tests.
  • Swap the video cable and input type. If the monitor is on VGA (analog), try DVI/HDMI or a known-good VGA cable. Reseat connectors and test again.
  • With the PC set to 1024x768, use the monitor OSD: run Auto/Auto-adjust, try the different aspect modes (1:1, Aspect, Full), and perform a Factory Reset. On VGA inputs, adjust Clock and Phase slowly to see if the alignment improves.
  • Check GPU driver scaling/refresh settings (NVIDIA/AMD/Intel control panel). Force 60 Hz and try both "GPU scales" and "Display scales" modes to see if behavior changes.
  • Boot the monitor from a second PC with 1024x768. If the fault follows the monitor, the internal scaler/firmware or panel electronics are likely bad.

If none of the above cures it, the monitor is probably failing (internal scaler or analog front end). Warranty service or replacement is the practical route; repairs are possible but often costly. Do not open the monitor unless experienced — internal capacitors can retain dangerous charge.

I think it may be your monitor. Test another monitor to be sure though.

I have recently upgraded my graphics card and tried the resolution again, i have the same problem! decided to test another monitor and it works fine. could it be the cable at fault? The t.v. works fine.

must just be your monitor not liking that resolution for some odd reason.
when you view it as a TV, are there different size settings, ie widescreen, fullscreen, 16:9 etc etc?? if there are you could try all of these, to see if you get a problem with any of these.
the monitor could just have a bug when displaying in certain ways.

yeah the monitor does have different setting for the t.v. 4:3 & 16:9
I have tried 1024x768 on the different setting but half the text on the left and half the text on the right is missing!! its not jumbled though.
thing is when i first started using the monitor it worked fine!!
