Default Vision Master Pro 512 HM HA202DT screen position changed after standby/switchoff

Hello,
I have an iiyama Vision Master Pro 512 HM202DT CRT. It works, but after it is switched into standby mode (computers sends no video signal), the H and V position and the size is changed. I can set them in the monitor's settings menu, but after the monitor is being switched off it is changed again.
I know that after startup of a CRT the position changes a little bit, but it will result in the same setting as made before (experienced with another CRT).
In my case, the size and the position is changed after I switch it on again. This also happens if I completely switch the CRT off with the power circuit breaker switch on the right side.
Does anybody know where's the fault?
Kind regards
Pentium4User

EDIT:
Does not happen with my Daewoo 712D CRT: I use Ubuntu 19.10 (tried different GPUs (GeForce 210 (nouveau and nvidia), Radeon HD 4350)).
Found a German thread describing the issue: https://www.forum-3dcenter.org/vbull...p/t-28738.html

Just a guess, but if the data is stored in an eeprom (24Cxx) ic it could be corrupt, I found a service manual for a vision master pro 451, I don't know how similar it is to the 512, it might be completely different.
