Hi, Sounds like an issue of the video card not the monitor. Take to computer shop to verify. One thing you can try is drop the dpi down (refresh rate)a bit. Then try again. If that makes sense to you. Hope that helps.

are you in dual screen mode on a laptop possibly? Check that the laptop is dual enabled so that it is either an extension or a duplication of your main screen. This is common mistake in setting up external monitor on laptop.

you need to look at the geometry settings on the video driver on your computer to find the right set for your monitor. There is some adjustment in your monitor to choose 4:3 or 16:9, but in PC mode this is usually over-riden though.

check your VGA cable and connector that it is securely connected. Sounds like the blue is open or disconnected. If not, the video card on the PC or the receiving card in the monitor is going out,

Don't forget to adjust your setting on the computer as well.
