Updated Intel Iris XE Graphics Driver resolution

[kimmi]

My Computer updated to the newest version of the Iris XE Grapics - 32.0.1015972 and now the higest resolution y extended screen (A 4K Hisense Smart TV) can go is 1920 x 1080 whereas before this it was 3840 x 2160 which is what I need it to be. Is there a patch or previous version I can download to be able to use the higher resolution. I even bought a 4K HDMI to ensure that wasnt the problem
