Windows 10: Display error - Getting colored lines and dots with a sudden sound

In my windows 10, I am getting display error. Normally laptop is working fine and suddenly, a display error, which shows colored lines or dots or black screen, and with a sudden sound. Once, I removed mozilla browser and this problem vanished for sometime. But again from some days it again started popping up, while working with Edge browser. Not able to understand whether it's system issue or display issue?

How to reset the display settings, color resolution, basically everything to do with color?

Oh I see. Well to set the resolution, you can right-click wallpaper and choose Display Settings. I'd make sure your resolution is set to the native/recommended resolution that actually matches how many pixel dots your screen really has.

But then the color settings, I'd try this:

• Go to Settings > System > Display. Scroll down and choose the Display Adapter Properties link.
• Go to the Color Management tab, and click the Color Management button.
• Go to the Advanced tab, and click the Calibrate display button.

If that still doesn't get it back, I'd also try this:

• Click Start to show your Start menu, type "clear" into the keyboard and choose the "Adjust ClearType Text" option.
• Follow this tool to tune your display more.

Beyond that, the next steps are usually to use either the display's buttons to adjust the contrast/brightness. Although if you're on a laptop, those buttons may not exist. The laptop builder might have some software for their machine, but it varies around
by builder.

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue

 

HP Deskjet 6940 printer has stopped printing color all of a sudden

Original Title: No longer printing color

I have an older HP Deskjet 6940 printer that has stopped printing color all of a sudden. There is ink in the cartridges and nothing else reports in error. I have tried all the suggestions here but to no avail. Any suggestions?
