Hello , I am having a problem about Eyefinity technology use

Currently , My computer system was composed of two graphic card.


 - 1. MSI HD 7970 Lightning Boost Edition D5 3G

 - 2. SAPPHIRE Radeon  HD 7750 OC D5 1G

And , Main board "ASUS rampage 4 Exetreme" use.


The four Mini DP ports in this 7970 card were connected to "SAPPHIRE Active MINI Display Port to Single-Link DVI Adapter".

Then,  connect "DVI to HDMI cable(5M)" to DVI port.

Next , TV(monitor) connected HDMI port using "HDMI to HDMI cable (3M) ".

I have connected cable by succession.  


1. Mini DP -> Active Mini DP to DVI adapter 

2. DVI -> DVI to HDMI 

3. HDMI -> HDMI to HDMI 3m 

4. HDMI-> TV (Only HDMI port available)



The DVI port of 7970 graphic card was connected "DVI to HDMI cable(5m)".

And then connect to the same method  the TV with "HDMI to HDMI cable (3m)".

1. DVI -> DVI to HDMI 

2. HDMI -> HDMI to HDMI 3m 

3. HDMI-> TV (Only HDMI port available)


The second graphic card HD 7750 is using to connect to the KVM.

Could You know what I mean?


I had been using  the total five channel of 7970 graphic card since April 2013,

Recently , However, I have several problems.


symptom 1. The one of five channel is not output randomly.

symptom 2. All of channel aren't output.

symptom 3. The one of five channel was broken screen randomly.


Usually , I'm well using. but have symptoms so often.

I don't know why cause of these symptoms.

I don't want to hear news that the card is out of order.

I am doubtful about graphic card performance and how to use and a lot of connection between cables.

Please I really need your help.

I would like you to know if you have solution.
