sorry missed a bit originally ...trying again now
done. displays a couple of pages of code including 16 lines of code for EDID
Have done this correctly now and have a cursor flashing for new input
Not sure how to do this. Do I just type those commands and enter?
Yes, pressing enter after each line. They are separate commands. You also can use Copy and Paste with right click to save the typing.
Hi, completed that process but still no go and no options in display settings to change.
Are there other workarounds?
really appreciate your help here, and if nothing else, its been a good learning curve...
Is it possible to flash the firmware on the monitor via usb? Only problem with that is getting the firmware. It seems getting a download from Acer might not be easy.
It wouldn't and flashing a monitor would be a lot of hoops to jump through.
What is your terminal output for
Given that newmode and addmode did not work (It should have, even temporarily) and adding an EDID did not work (surprising), I am at a bit of a loss on this one.
I know that you can buy EDID spoofers - we usually use them on headless machines or kiosks and the like. It is an adapter that connects between the monitor and computer.
Incomplete question. Were you intending to ask OP to enter a command, or was it a typo?
Ok I might take a look at that option. It might be that I just bite the bullet and get a new screen because I really do want to ditch windows and I'll keep the rogue monitor with the old pc it works ok with as a spare.
Is there any chance a new monitor will not pair with zorin os?
Yes... my ctl+v apparently missed... I am a failure.
I will go flog myself.
(It was supposed to be ls -l /sys/class/drm/*/edid )
I think that chance is exceptionally slim. But, you have definitely checked the cable you are using, before buying a monitor?

Yes, see, each file shows a size of Zero Bytes.
I think a spoofed EDID is where we are at.
Yes been swapping out cable with good screen, and have tested with another cable also. Strange the monitor still works with my old pc. Windows must remember the original handshake yes? Those spoofers are the price of a
budget monitor here and no guarantees of success so might as well go for a new screen. Gave it a good crack though and I really appreciate your help thankyou. At least the fault is now diagnosed...
My experience goes back a few years on that... There are factors that affect and raise prices a lot going on, right now.
It can fallback to previous saved states, depending on the GPU.
But in general, Windows OS is a lot more tolerant about missing values.
GnuLinux uses Kernel Mode Setting. This is a security and safety consideration.
If the monitor is not properly displaying the EDID or simply, not relaying the right signals, this can damage other hardware. In GnuLinux, the risk is not taken, whereas Windows OS ignores it.
