So, I have this issue
I have a Surface Pro 4, Core i5, 8GB, 256SSD
Only started recently when I hooked up a 4k widescreen monitor.
Call support, they requested a video of the behaviour whilst in the EUFI screen.
problem is, as soon as the problem manifests itself whilst working in windows, when I reboot and get the EUFI screen the screen stops juddering.
Anyone know how to force this to effect so I can take a video of it and get a replacement?
Support are pretty shocking. They kept emailing me for updates, to which I kept responding that I am still trying to video it in EUFI, then they got fed up and closed the case without my permission! NEVER had this with any support people!
