I have just bought a Dell Inspiron 14 7000 (7400) and am using Ubuntu MATE for the first time. I love it, but there is a problem with the monitor. The colours are unnatural, some seem faded and others too bright. Peoples faces look yellow and some pics are slightly blurred.
On Dell specs the Graphic/Video Intel(R) Iris(R) Xe Graphics with shared. On Ubuntu MATE Graphics: Mesa Intel® Xe Graphics (TGL GT2)
I have spent days trying to fix this and looking up help websites. But because I only know computer basics, I am hesitant using the Terminal very often, as I am unlearned in that area.
I tried Software/Updates --> Additional Drivers with the answer 'No Propriety Drivers Available'.
Then 'Available Software out of date'. I tried to update and received 'error while refreshing the cache'.
I hope that someone can help.
