    Hi,

    I want to use 2 monitors on my Mac pro begin 2009 8 core 2,26 Ghz. I have 1 Led cinema display and now bought Dell U2515H. I connected it on the DVI dual link port of Geforce GT 120. Unfortunately I am getting no display on that monitor. I have Osx Yosemite

    I have connected the Dell monitor with a cable from DP to DVI.

    Has someone a solution to this problem or any ideas how I can solve this problem?

    Kind regards,

    Frieda

    So, mDP or DVI? Hooking it up on the DVI port should always work, mDP->DVI adaptors might be a bit picky, the passive ones are not Dual-Link capable.

    The problem is solved.
    I used a HDMI to DVI-D cable. Mac Pro recognized the monitor although Dell monitor did still hava a black screen.
    I systematically start with the lowest resolution way up to higher resolution and suddenly the monitor works.

    Kind regards,


    Frieda
