AMD EyeFinity - Issues with Triple-Screen setups and 120Hz Refresh Rates

Getting it to work, no thanks to DisplayPort


Sapphire was very kind, and sent me three of their Radeon HD 7970 Dual-X 3GB OC GPUs, which actually were much better. This is because they have a full-sized DisplayPort, but two DVI ports. One of which is just a single-link DVI port, but I've found it actually pumps out 120Hz... So, I'm not complaining.




I have dumped in two of these cards into my rig and voila - EyeFinity at 120Hz, but it still has issues. I have to mess around with monitor drivers before my Alienware monitors will detect properly at 120Hz, or at more than 640x480.


This is all because of DisplayPort - on an NVIDIA-based configuration, and all dual-link DVI, it just detects and works. There's just magic, and I love it. With AMD, and their decision to force DisplayPort, it does not like 120Hz at all.


This isn't a major issue for AMD, or most consumers, but for those who want to run one of the most harshest configurations on a GPU - triple screens at 120Hz - don't buy AMD, or at least, buy all DisplayPort-capable screens.


With DisplayPort-capable screens, the above issues disappear. I haven't personally tested three DisplayPort and 120Hz-capable screens in EyeFinity, but I don't see how it wouldn't work. It's the conversion process and the dual-link DVI monitors that are getting in my way. I just wish AMD would support this configuration. It's not like it's some super unique cheapo monitor setup that I have.
