ATI Radeon HD 5770 extension problems

Question asked by drevolution on Jul 8, 2015

Hello,

 

I´ve a Mac pro with ati Radeon HD 5770 (with 1 DVI output and 2 mini DP outputs) the computer is about 15 meters from the monitors and I would like to extend the video signal for two 1920 X1080 monitors.

 

The DVI is extended with rj45 adaptor with no problems from the DVI output but i can´t get more than 1600 X1200 while try to output from the miniDP ports..

 

I tried from mini DPport to VGA direct to the second monitor (only supports 1600 X1200)

Also tried from mini DPport to DVI and a rj45 extensor http://www.visus.pt/mirrors/sc&t/SC&T%20User%20Manual%20-%20PDF%20format/DVI%20Transmission/DE01E,DE01ERK.Rev%20B.pdf  but i can´t get image to the monitor.

 

options?

 

thanks in advance.
