Monitor display partially transparent [Ghosting]

[mikeh]

Hello,

I have a HP E272q monitor, and for a few months I've been noticing that there appears to be a central division in the display, with the left hand side showing a degree of transparency that is most noticeable on dark backgrounds. For example if using Autocad with a black background, I can see a "ghosting" of other windows behind (eg like a browser), but only on the left side of the monitor centreline. I'm not sure but this may have only started after upgrading to Win 10. It was originally Win 7. Is this something anyone else has experienced?

Hi,

Do you have a different monitor that you can try ?

Just to identify the cause.

 

Have you tried re-installing the graphics card driver software ?

Thanks for the suggestions Ken.

I haven't got a second monitor to try unfortunately. The monitor I have uses a "DP" cable. The PC is an HP Z440 workstation.

I have just reinstalled the monitor driver and graphics card drivers with the most up to date ones, but no change.

I'm not sure if I've described the issue very well, but the attached photo shows the screen during start up - and you can just see the "ghosting" of my browser bookmarks on the left side, while the right side is black. You can clearly see the difference between left and right sides. It seems odd that even during start up, the image of my browser and the desktop icons is visible.

I think what you are experiencing is "Image Persistence".

It is similar to Image Burn with older CRT monitors.

It is caused by leaving the image - in your case the Bookmarks /Desktop- static on screen for a period of time.

The image is "burned" into the pixels of the screen.

This is why you can see the "Ghosting" on Start-up.

 

You can sometimes fix this by leaving the monitor switched off for a long period of time - possibly up to a couple of days.

Try it over night initially.

 

You could also try typing .....about:blank .....[there is a colon after the t ] into the address bar of your browser and hit "Enter".

This will flood the screen with pure white.

Then press F11 to adjust the density to max

Leave this white screen for some hours.

 

To prevent this in future put a screen saver on to kick in after a few minutes of inaction.

Thanks Ken,

I have given this some more thought, and tried what you suggested. However I actually think it's a fault with the monitor. For example I had the same "image persistance" with a pdf I'd only had open for a couple of minutes. I could also see the image persistance flickering while doing some other tasks, and it didn't make sense that the effect was only visible on the left side of the screen - the right side is 100% normal.

I will try to take it up with HP - the monitor is only 18months old.

 

Thanks again.

The split screen did have me puzzled.

Let us know how you get on.
