DisplayPort 1.0/1.1 is limited to 360 MHz with 8-bit color and 480 MHz with 6-bit color. The monitor must support DisplayPort 1.2 and HBR2 (High Bit Rate 2) mode to go higher. You might be able to squeeze in a 1500 vertical total by reducing the horizontal total to 2000 (with the front porch or sync width reduced to accommodate) if the monitor can handle that.

Yeah I know. I was at 359.94 MHz by reducing the HT to 2001, but the resolution still didn't show up. I didn't even have an option to switch to 6 bit color, because the refresh rate didn't show up. At 359.94 MHz and lower on my R9 290x, I can choose 6 or 8 bit. At 360 MHz+, it's 6 bit only. I had no problem with this on the R9 290X.

The problem is, this isn't working on the Geforce...only on the 290X.

Also, the "advanced adapter settings" didn't open at all when I did the 120hz custom resolution. I'll remove it later and only do the 100hz one and then see if I can get that window open. I hope I didn't run into a windows 10 bug ...(I'm extremely new to 10).

Anyway, to refresh: with the mini displayport on the Geforce 1070 on the laptop, the refresh rate doesn't even show up at all. It's like, not there. And the limits are in range.

2080/1500 should be 374.40 MHz and 6 bit color only, but it didn't show up in the NVCP.
2001/1500 is 359.94 MHz, and should work at 8 bit color, but again it didn't show up in the NVCP.

So I was wondering if somehow there was a limit in place that doesn't happen on desktop cards. Or maybe I'm still too new to Nvidia. I am in windows 10 on the laptop and 7 on the desktop. I was just wondering if I'm doing something wrong.

I'll mess around with it later when I hook up my laptop again, but that's really bizarre.

As always, thank you for all your help. Sorry if I'm nagging.
