Second Monitor Display Is Blurry

[KingKrusher]

I have an external Samsung display for my Windows 8 HP ENVY laptop.  It works great, I use it as a separate monitor in addition to the laptop display.  The issue is however,  that if I turn on the external display first, the laptop display is slightly blurry while the external display is crystal clear.  If I do not use the external display, the laptop display is perfect too.  I've tried re-installing drivers but the situation is the same.  At one point the HP technician took control of my computer and temporarily fixed it, but the next time I booted up I had the same problem.  Any ideas?

Hello, @KingKrusher 

Welcome to the HP Forums.

I see that your notebook display is blurry when using an external display. I will try to assist you with this.

Here are some documents that may help.

Read though both to see if either can help you. Let me know how this goes.

Thank you for posting on the HP Forums.

None of those worked.  I tried re-installing the monitor driver too but that didn't work either.   One question, why does the monitor still work after I uninstalled the driver?  Seems like you wouldn't be able to use it without a driver.

Hi,

When you uninstall the driver, you still have the Windows default driver to allow the display(s) to work.

When you uninstall the driver, are you checking the box to delete it too? If not uninstall it once again please and check that box. When you restart this will force the computer to use a Windows generic driver. You can then go into device manager and search for updates online, if you wish. If the issue happens with this, then it's happening on two different drivers.

You could then try using the HP Recovery Manger, to restore the graphics drivers and chipset back to factory default. Test again, to see if you have the issue. If you do, use the HP Support assistant to update both of those drivers.

Let me know if this helps.

I don't see a box to delete the driver.

Hi,

When you go into device manager then right click on the graphics driver, properties, then uninstall. You should get a pop up Window before anything happens. This is where you'd see the box to check, should say something about deleting the driver.

If you don't see that, skip that step.

I don't see a checkbox.  Plus I already tried uninstalling and reinstalling the driver and it didn't work.   It could be an issue with the monitor itself.  I can get a replacement from Samsung.
