Having issues with the resolution on my extended monitors. 
Both monitors are Cepter C34ATILIUS2 34" monitors. 
Can have 3440x1440 resolution on one monitor and the other monitor I can only get 1920x1080 resolution. 
All drivers etc are updated. Any suggestions?


In addition, I've tested the setup with a Lenovo laptop, then both monitors are working  in 3440x1440 resolution.
