Modding with IPS screen is fairy easy nowadays with the GBA there is some no soldier options not sure if that is the same with an original dmg.

Another option could be a Epligoue GB operator, which allows you to play your original cartridges on pc.

Interesting might have to give this a go in a dual boot.

To be honest HDR wasn’t something I even thought about, as my primary usage is development. To be honest with my use case I don’t personally see it as a necessity but could be convinced otherwise.

That has certainly been my preference in the past, and at the moment I’ve lost one of my monitors to my wife, which is even more painful.

Thank you for your response, agreed it is definitely a preference thing, I’m just looking for a few ideas to hopefully narrow my initial search.
