HP Thin Client resolution too high

[Chrisnse]

I have a HP Thin Client T5545 . I accidentaly put a wrong screen resolution and now when I start it I have a message on my screen Input signal out of range, so I can not change it again or do anything.

Is there anything I can do about change the resolution?

Thanks for your help

I'm having the same issue with a HP Thin Client T5000 (using Linux embedded), I need to restore the original resolution. Please help us!! 

Thanks!

Have you considered reinstalling the OS

for the T5545, the last image can be found here

or

If you have more T5545 you can copy the OS image from 1 TC to another by using HP ThinState Capture

Thanks, but in my case I have a HP T5000. Finally I've fixed the issue without reinstalling the OS. This is how I've solved: I connected an old CRT screen and I was able to change the resolution there!

Another potential solution:

If you have old HPDM sever, e,g, v 4.3.  You can try to modify the resolution by Task Template - Apply settings - Ｄisplay settings.
