Issues with screen resolution Monterey

I have installed Monterey (trough OCLP) on my Mac Pro 3.1 inc metal compatible graphics card. in the past it worked seamless let but had to do a reinstall and now only have a resolution of 800x600 and have tried quite a lot of things but I can't get it resolved.

Who has some advice to deal with it?
