Ok, so currently I have a Radeon R7770 graphics card running a dual monitor setup using the DVI -I connection with an adapter (to VGA) for a side monitor and an active adapter on the DisplayPort connection (to vga again) to my main monitor. When I try to add another monitor with the HDMI connection (using an active adapter to VGA), it doesn't detect. It's not in the Hardware Manager, not in Display Setting, and not in the AMD Catalyst Control Center. The monitor seems to detect that it's plugged in, but it just says "power saving mode" and goes to sleep.
Whenever I disconnect the side monitor (that is working) and try to put it the hdmi port it does the same thing. It goes to power saving mode and doesn't detect.
I'm almost certain my GPU can handle it, as it supports Eyefinity and everything, but it just wont detect.
TL;DR I've got the DisplayPort used on my main monitor and the DVI used for my side monitor. I want to add a third screen using HDMI but it won't detect.
Any ideas why?
