Every other line of pixels on the right half of my screen are dark. What's wrong? How to fix?

Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:
Use the buttons on the front of the display to open the on-screen menu, and select Factory Reset or Default.
If you need help using the on-screen menu, see the manual for your display.
Unplug the video cable between the computer and the display and check the ends for bent or broken pins. If any pins are damaged, replace the cable. Otherwise, securely connect the cable between the computer and the display.
If the display has more than one type of connection available such as VGA, DVI, or HDMI, try a different type of connection.
If possible, connect the display to another computer. If the lines appear when the display is connected to the second computer, the display might be damaged or defective.
If the lines disappear when the display is connected to another computer, connect the display to the original computer and continue to the next step to update the video drivers.
If you have an HP computer, update your video drivers from the HP website.
Otherwise, you can get the latest updated video drivers from the video hardware manufacturer's website. The following list shows some of the video hardware websites:
If updating the drivers does not correct the problem, the graphics adapter might be damaged.
Typically, video cards are damaged by too much heat caused by an accumulation of dust around fan areas. Cleaning the components inside the computer, especially the graphic card, might correct this problem.
Hope this helps! Keep me posted for further assistance.

Hi HP Support Team & Echo_Lake,
Thank you very much for all your suggestions. I have had a lot of things going on, but I have followed the suggestions. (I only have a VGA type connection).
I connected the display to my HP EliteBook 8440p and what was obvious, but hard to see with my desktop was a webpage showing with sort of a greenish color on the right side of the screen. I don’t know how to get rid of that page. That must be what’s causing my problem. Can you, the HP Support Community, tell me how to get rid of ghostly webpage?
I didn’t think of taking a photo of it to send at the time. If necessary I can get that laptop and go through the switch again and shoot an image.
I hope there’s a simple solution. Thanks for your time.
