Brief summary and a practical way to narrow this down quickly (builds on the hints from and without repeating them).

First, isolate hardware vs software with a screenshot test. Press Print Screen, open Paint, paste and save the image, then view that saved file on a different computer or send it by email and open it elsewhere. If the saved image looks sharp on another screen, the problem is with the laptop’s panel/cabling/inverter or how the panel is being driven. If the saved image is also blurred, the issue is inside Windows or the video driver.

If it looks sharp on another screen

  • Check whether the boot/BIOS text is blurred before Windows loads. Blurred pre-boot output points to a panel or cable problem. Gently open/close the lid and watch for changes (loosening/twisting can reveal a damaged LVDS cable). Do not disassemble the laptop unless comfortable — get a service tech if under warranty.

If it is blurred in the saved image

  • Treat it as a software/driver issue. Reinstall the Vaio video driver (use the exact model download from Sony or the GPU vendor). Make sure color quality is at the highest setting and font smoothing/ClearType is enabled. Open the GPU control panel and look for any scaling/sharpness options and set them to no-scaling or 1:1 where possible. Try Safe Mode or a Linux live USB to see whether the problem follows Windows.

Extra checks

  • Toggle external-display output with the Fn display key to confirm Windows isn’t stuck in a strange output mode. If nothing above helps, note the symptoms (whether pre-boot is affected, whether the screenshot is sharp) and cite them to the repair shop or Sony support for faster diagnosis.

Member Avatar for caperjack

go into the properties of the video card and check the refresh it may have changed ,not sure what the laptop should be, but i think its should be 75,hooking it to the projector may have changed it to 60 or so,i have seen blurry laptop screens when set to 60 mhz
