Question about HP Pavilion zd7020US Notebook

3 Answers

ZD7020US Display Display is in 4 segments.About 2 inches of the top of the screen disappeared and reemerged at the bottom.About 4 inches of the screen shifted right and reappeared on the left side of the screen.You can actually have the cursor go out the right side of the screen and come back in on the left or go out the top and come back in at the bottom.I hooked a monitor to the laptop and it works great on the external monitor.Any ideas what causes this problem?

    No. 1 solution not a fix.reinstalled system and all drivers but did not fix. As stated if you hook another monitor to laptop it works fine. ???

    I left out one important possible clue. I drive a truck and was at a stop and viewing a gps program when i restarted the engine of my truck when this problem arose. I figure it was possibly caused by a voltage surge for I was using a inverter to get my 120 from a 14 volt source. After I started my engine my computer shut down and when I restarted my computer I had this problem.
    ANY IDEAS ???

    Yes, I have the same problem! The screen is segmented, shifted up 2 inches and right 4 inches. Only the left inch of viewable area (where the start button is) is not viewable.

    I did hook it to an old external monitor and it viewed fine for about 60 seconds until that monitor decided to quit entirely (had been in the attic for 2 years).

    I have successfully hooked up to another external monitor. Can use the computer fine from it. Any ideas on fixing the laptop screen?

    Occasionally vertical stripes will appear within 1/2 inch of the right hand side of the screen, from top to bottom.

    Fixed the problem. There is an inverter board that runs between the display and the computer itself. This is mounted on the back of the display screen. No problems since replacement of inverter.

The answer may lie in getting your video card fixed
or resoldering the display screen wires.

Sounds like you have the wrong monitor drivers installed,  download updated monitor drivers from the manufacturer's website,

also check your display settings,  as something is really wrong there.

Attach an external monitor to your PC. If the problem continues there, it's your graphics card.
If the problem disappears, you have stuck/dead pixels.
You could try a very gentle rubbing of the pixel(s).

Screen border


You are probably in the "3:2" ratio print setting. This is accessed through the "F" button, under image quality. The 3:2 is a ratio of height to width which corresponds to a 4x6 inch print. The other settings are approx. 4x5.33 inches in h to w ratio. Just change the quality setting to the larger megapixel settings and the bars will disappear.
