Multi-Display HELP!!!

chubbs296 · January 23, 2022

So I've been stuck at work since 10 this morning(currently 6pm) and I've been trying to solve an issue with our new tv walls. We bought 3 VisonTek Radeon hd 7750 eye 6 graphics cards and put them into 3 separate prebuilds. I updated the drivers to the newest version that i could find for the cards but I'm running into some problems. The computer will only display to 2 monitors at a time despite having 6 ports and advertising that it can do 6 at a time which is what we need. We're running HDMI fiber cables to the pc and using an hdmi to mini DP to connect it to the card. The cables are fine as they actually produce a signal if it's one of the 2 plugged in. All the ports on the card work. The computer shows that more displays are connected but it doesn't automatically display to them nor does it let me change any settings for that display. Any ideas on how to fix this? Thanks

Are you using active adapters? Their FAQ appears to cover this: https://www.visiontek.com/products/radeon-7750-2gb-gddr5-6m-6x-minidp

Why can't I get video output from more than 2 monitors?

If you are converting your connection from a DisplayPort signal (mDP, DP) to a non DisplayPort signal such as HDMI, DVI or VGA active adapters are required after 2 displays.
