Dell Vostro 2420: pink and grey lines on screen after Windows 10 upgrade #

Four years ago, RockNir posted Weird Lines and color changes suddenly appear on screen. What's happening? to the Dell laptops general forum. It read in part, "[My] Dell Vostro 2420 has been behaving weirdly at times ... pink and grey lines suddenly appear and cover the entire area of the screen, generally when I am not plugged in ... This problem started after I upgraded to Windows 10..." and included this image:

Sadly, the forum has since gone read only, so I am posting the solution here in hopes that RockNir (and anyone else facing this issue) finds it:

1. Control Panel > Intel Graphics and Media
2. Advanced Mode > Power > Power Source: On battery
3. Under "Power Conservation Features", uncheck "Display Refresh Rate Switching" and "Display Power Saving Technology"

Verified both the problem and the solution on a Dell Vostro 2420 running Windows 10.
