Visit the HP website and find the various drivers for your machine. See if they have an updated video driver for you. (You'll need to compare the date and version number to the current driver displayed in "Device Manager" under "Display Adapters".) If so, download it and install it..
If HP doesn't have a newer version of the video driver, try visiting the video card manufacturer's website and see if they have an updated driver for your specific card. If so, then download and install it.
No guarantees, but it's worth a shot.
Hope this helps.
I have had my hp laptop for a while now, and for the last six months ive been experiencing some sort of glitch on my screen. It has been happening off and on for weeks at a time (usually brought on by restarting my computer due to an update). What happens is my screen's display will literally scale down and shrink, which leaves a dark void about two inches on the right hand side of my monitor and a half inch on the bottom (i cannot even move my mouse into this void). Ive tried messing with the display settings but NOTHING WORKS. My screen resolution stays at 1024 768 regardless if its working properly or glitching. My screen cant be broken because, like i said, sometimes after restarting my computer it will go back to normal. The only advice ive had so far is that it may be a problem with my video card. Any ideas?
this is a picture of what it looks like when its glitching. when i took the screenshot, the black voids didnt appear so i added them in with photoshop. notice the the bottom void and how it distorts the startup button.
