Thankyou kindly for your response.
That is correct if i open archicad 22 on my laptop its fine.
When i plug the external screen in and then open a new Archicad 22 directly from my new screen (HP Pavilion 32HD) then it crashes
. Also if i open archicad back on my laptop screen, while the external screen is plugged in it does not crash
I noticed it also when i purchased a 4K screen as well (i have purchased and returned about 8 different screens). It bizarre i asked my Archicad Manager in my other office and he has never heard of it.
I sent the error message to Graphisoft last night
When i use an external screen of low quality it works fine.
I decided to take a big step and last night download my Archicad 23 and it seems to be working fine with Archicad 23, however all my projects are in 22 which would be good to retain as a workable option.
