HI,

For Christmas I bought myself an HP Pavilion dv76b55dx Entertainment PC with Windows 7 Home Premium (64) bit. As soon as I turned it on I noticed that the screen has a slight blue tint. Also the colors are inaccurate. Whites have a bluish tint. Reds, yellows are too bright. Pinks can something look orange. Dark purples and greens looked washed out - for lack of a better description. At first I thought it was that's the way the new LCD screens were. But adjusting the brightness and gamma has made no difference. I also made sure I updated all the drivers etc.

I finally got fed up and contacted HP via email. They wrote back and said I may have a corrupted graphics driver. Then gave me instructions to try to fix it which seems more complicated then need be. They want me to re-install the OS from the recovery drive. If that doesn't work they I'll have to send it in for them to fix.

Is there a simpler way of fixing the corrupted graphics driver without doing the reinstall? I don't want to do the OS recovery thing. Sounds too complicated. Plus I'd loose all my programs. It has an Intel HD graphics card.

Any advice would be appreciated.

Start/Run...type devmgmt.msc and hit Enter.

Scroll down to Display Adapters, double-click.

Right-click the detailed item, click Properties.

Click Driver tab...click Uninstall, click OK. Close other windows.

Reboot the system.

Let us know any change or lack thereof.

Hi

Dumb question. But I want to be sure. Do I check the box that says "Delete the driver software for this device" when I click uninstall.

Thank you,

Ziva

Okay, I gave it try and marked the box to give permission for the software to be uninstalled. It took a few minutes, then rebooted. When desktop came back all the icons were huge and the task bar was also taller. After a moment or two the pop-up appeared and showed that it was searching to install the graphic display driver. Too a few minutes then had to reboot. When desktop returned the icons were small as was the taskbar. But the screen was real dark. Then after a minute it brightened. But there was no improvement as far as the blue tint goes. Plus reds and yellows are still too bright.

Guess I'm going have to send this in for repairs. What a rip-off considering it's barely 3 months old.

Thank you for your help,

Ziva

Ziva, I wouldn't' say ripoff unless they didn't want to fix it under warranty.

Before you send it in back up the hard drive. Unless of course there is nothing on there you care about.

If there is nothing you want on the drive I would do the system recovery. I might do that anyway after backing things up before shipping it back.

Warning, This will wipe everything off of the hard drive.

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01895783

From that page I would follow the instruction to
"Create a set of operating system recovery discs"
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01895783#WhenCreate
and then
"Restore the PC to its original condition with the HP Recovery Manager from within Windows 7"

Good Luck

Thank you,

I will give it a try. HP also recommended I do a recovery.
