Question VG27AQL1A: HDR on DisplayPort cable?

Apr 8, 2020
Basically I read with this monitor that I could use HDR on HDMI, and G-Sync/144Hz on DisplayPort, but I couldn't have both at the same time. I saw a few people complain about this on Amazon reviews, and found it confirmed in a professional review so I had planned just to not use HDR. But I've noticed in Windows it does give me the option to turn it on.

I haven't had much experience with HDR, I don't know if I could really tell the difference. I'm wondering what drawbacks would there be to turn on this feature for a monitor that isn't supposed to support it on this DP standard. Would it just not work? Or could it cause other problems?

I'm using a EVGA GTX 1080.
