    Can't set custom resolution to 4k 50Hz "Exceeds Bandwidth"

    bobdvb

      I have an LG 27UD68P 4K display which supports 50Hz modes in HDMI (but not 4K) and I have it plugged in via DisplayPort from my i7 with Intel 520 graphics.

       

      4kp60 works fine but it doesn't provide an option for 4kp50, when I go to set Custom Resolution to 50Hz it says the resolution "exceeds the maximum bandwidth". But 50Hz is lower bandwidth than 60Hz so why would I get that message?

       

      I would accept a refusal based on the LG refusing to support 50Hz but I don't understand the message from the Intel graphics tool!
