Windows 10: Display distorted

My Dell laptop has multiple horizontal and verticle lines across my start screen, some blocking my task bar. WHY and How to fix ?

Windows 10 Distorted Display

Mine was not back to normal upon re-boot either, because I had display resolution to adapt to the distortion. (Everything was very small). Changed the display resolution from 1920 x 1080 to 1600 x 900, and everything looks good now.

 

sound distorted after windows 10 anniversary upgrade

This is where I'm at on my HP laptop with Windows 10 and the Anniversary update.

I completed step #3 "hardware and sound" but that took me to an option for "sound, speakers." There was no "properties" as step #4 suggests. I selected "sound, speakers" and then found "properties." After selecting "properties" there was no "enhancements
tab" as step #5 suggests.

Regardless, I then uninstalled the realtek audio driver. I noticed that when I did this without restarting my laptop that the sound was now tinny, but not distorted as it was previously. After restarting, the sound was again full, yet distorted.

Realtek still shows in my programs list, though it shows no memory is used.

Thanks for your continued help.

 

Screen Display is Distorted

Upon logging on this morning, my (Windows 10) screen display was distorted horizontally - stretched sideways, basically. The Icons were all larger than normal, as well.

I have played with various "Display" and "View' settings, and also searched for a Graphics Driver update (was told I have the latest driver).

Any suggestions? Thanks!
