Shutting down of just display going black?
If latter, you can keep touching screen to let it know not to sleep; or go to the system controls and set "sleep" to 1 hour or longer.

Acer s211 HL monitor, blibks like crazy and cant see video on full screen display, but works in small window format. Can not seem to download drivers from acer? Is it my drivers?

First check the resolution and refresh rate for your video graphics adapter. LCDs are apt to blink when not at 60 Hz. (Recently I had another client with that issue.) For Windows 7, right click on the desktop and choose Screen Resolution. Click on Advanced Settings and the Monitor tab. (Other versions of Windows will have this in a similar area or Control Panel > System > Display in some combination. Mac and Unix have this setting somewhere as well.) Also make sure that you are set for the native resolution or one supported by both the monitor and the graphics adapter.

Next check the temperature of the system. Improve the cooling of the system if the graphics card is overheating.

I hope this helps.

My lg monitors screen is one vertical line red is comes up anothers is two horizontal line starting

This is an early indicator the LCD display is going and will only get worse. The only option down the road is to replace the monitor because the cost to repair will exceed the price of a new one.

Monitor display problem - patches of flickering dash lines

Has anyone ever seen such? This is a screen shot of my wifes HP Laptop. Fresh driver, updated DX, hooked it to a monitor and sent this to a few friends much smarter than me on computers. Lot of trouble shooting by direction but no results yet. Anything would be greatly appreciated.
