E420s - Graphics problems: blotchy looking unicolored areas/gradients

I have had this notebook for a few weeks now and I think it was like this from the beginning -I just didin't notice because I had only been working with text. Now that I wanted to edit a photo, it suddenly became very obvious that the visual display is somehow faulty. Areas with one color that is not 100% unicolored look like you used the spraypaint in ms paintbrush...

 

I googled the problem but only found one entry similar to my problem where a bios upgrade was responsible. Could this be possible? If so, how do I fix it?

Hello MysticRain and welcome to community,

 

First update the video driver and check if it resolve the issue. Kindly download driver  as per your video card.

Intel HD Graphics Driver for Windows 7 (32-bit)

Intel HD Graphics Driver for Windows 7 (64-bit)

 

AMD PX4.0 Graphics Driver for Windows 7 (32-bit, 64-bit)

 

 

If the issue persist then you need to update the BIOS. You amy choose Windows update or bootable cd update.

 

 BIOS Update Bootable CD for Windows 7 (32-bit, 64-bit), XP

 

README for BIOS Update Bootable CD

 

BIOS Update Utility for Windows 7 (32-bit, 64-bit), XP

 

 

Hope your issue gets resolved.

 

Best Regards,

Tanuj

It's probably just dithering. The display panel is likely 6-bit TN dithered up to 8-bit.
