AMD Radeon R9 270X Triple Monitor Problem

Recommended Posts

Hello Maldon,

 

I want to use 2 monitor and 1 TV at the same time. My GPU has 2DVI + 1HDMI and 1 Display Port

2 Monitors connected by DVI to HDMI cable and TV connected by HDMI to HDMI. Only 1 monitor and 1 TV starts or 2 monitors work at the same time but no success 3 ports!

Can you check run me post and advice?

 

Thanks.

Send me Sanelek-iMac.zip

In generosity and helping others, be like a river

In compassion and grace, be like the sun

In concealing others’ faults, be like the night

In anger and fury, be like a dead

In humility and modesty, be like the earth

In tolerance, be like the sea

Either look as you are or be as you look

CSM must be disabled, right?

Smbios was Mac Pro 6.1 and everything works perfect except third monitor. I will try with imacpro 1.1

sorry this configuration is little away to me to test and had just found a chance to try SMBIOS iMacPro1,1 and Mac Pro7,1 without success to display third monitor.

Can Hackintool do a trick? How can change connector, do you mean display port to HDMI to test?
