hello all, my wife turned on her computer today and the monitor was fuzzy. You can still read larger letters but the small stuff is to fuzzy to read. I tried a new monitor and same problem. Any thoughts on were to start, I'll be hones I don't know all that much about computer repair so please keep it simple.
thanks for the help

Because two different monitors look fuzzy, the issue is almost certainly the signal (cable/port, settings, or graphics hardware), not the screens. Start with the fastest isolation steps first, then move to drivers and hardware. Keep notes as you try each step so you know what changed.

  • Check it before Windows loads. Power on and open the BIOS/UEFI screen. If text there is fuzzy too, it is not a Windows setting. If BIOS looks sharp, focus on drivers/resolution.

  • Cable and port: Try a different video cable entirely (don’t reuse the same one). Inspect VGA pins for bends. If you are on VGA (blue 15‑pin), switch to a digital connection (DVI/HDMI/DisplayPort) if available. On an LCD using VGA, press the monitor’s Auto/Auto Adjust button.

  • Resolution/refresh: Set the display to the monitor’s native resolution at 60 Hz. Examples: 1280x1024, 1680x1050, 1920x1080. Using non‑native resolutions on an LCD makes small text look smeared.

  • Drivers: Reinstall the graphics driver cleanly (download from the GPU or PC maker). A generic or wrong driver can force bad scaling or timings.

  • About the card being turned off: If the discrete graphics card was disabled, re‑enable it in Device Manager, or in BIOS set Primary Display to PCIe/PEG. Then reboot and reinstall the proper driver. If it will not enable, continue below.

  • Isolate the GPU: If the motherboard has its own video output, plug the monitor there. If that looks crisp, the add‑in graphics card or its slot is suspect. Power off, unplug, discharge static, then reseat the card and its power connectors. Test again.

  • Still fuzzy everywhere with different cables/ports? The graphics card may be failing (often VRAM). Try another card if you can.

Note: CRTs can get fuzzy from magnetic interference; if you are using a CRT, move speakers away and try the monitor’s Degauss option.

You just go to desktop properties and change the display setting

I have tried messing around with the display and I think she has even turned of the grafix card.
