i got a LG 25UM58 ultra wide monitor however is having to run it through a display port to hdmi adapter as my htc vive has to use the hdmi port. Any ideas why the monitor will only stay in 1080p and not 2560 x 1080. Running a 1060 gtx 3gb windforce oc.
similar to this or is it the adapter.
You are using a DP to HDMI Type 1 passive adapter, which is limited to 1920×1080 @ 60 Hz. You need a Type 2 adapter for higher resolutions.
