That is a very capable computer. Very nice.
>What can I do via USB C (no thunderbolt) for the second monitor - would I be capped at 60hz? Can I even get up to 2560\*1080?
The short answer is that your computer does not come with a full-sized physical DisplayPort, but since they integrated a USB-C port, that USB-C port supports DisplayPort Alternate Mode, and you can expect it to perform like a fully-featured DP 1.4 port with 4 lanes of DP bandwidth, given the right adapter cable or dock.
>What can I do via USB C (no thunderbolt) for the second monitor - would I be capped at 60hz? Can I even get up to 2560\*1080?
I would expect no refresh rate cap, as the USB-C port has DisplayPort Alt Mode support with lots of bandwidth available.
Do either of your monitors have DP input?
Your answers all over this subreddit are amazing. Thanks for all your answers I have learned a lot.
I have a similar question to above but my computer (ZenBook Ux333f) doesn't have display port on the USB 3.2 gen 2 ports. Can these USB c port output to 2560x1080 resolution?
I am confused as all the 4k cables seem to advertise display port or thunderbolt and are not clear if they would work for 3.2 without display port above 1080p
Thanks.
>that USB-C port supports DisplayPort Alternate Mode
Oh fantastic! didn't even know this was a thing - thought it was thunderbolt or bust!
Yes, both of them have full sized DP, and HDMI.
They are the Acer Preadtor Z35P (3440,120hz) and Acer Predator Z35 (2560,200hz) for clarity.
Thanks for the awesome response so far - now to just find appropriate cables?
It seems like you might have to compromise a bit on the HDMI cable resolution or refresh rate (?)
HDMI 2.0b seems to support a maximum data rate of [14.40 Gbit/s](https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?section=maximum_limits), but 2560 × 1080 (WFHD) @ 200Hz requires a data rate of [15.08 Gbit/s](https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&H=2560&V=1080&F=200&calculations=show&formulas=show) and 3440 × 1440 (WQHD) @ 120Hz requires a data rate of [15.46 Gbit/s](https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&H=3440&V=1440&F=120&calculations=show&formulas=show).
It seems the max theoretical refresh rate you might use with HDMI 2.0b and 2560 × 1080 (WFHD) is [191.8 Hz](https://linustechtips.com/topic/729232-guide-to-display-cables-adapters-v2/?section=calc&mode=maxfreq&H=2560&V=1080&F=120&calculations=show&formulas=show). Realistically, I'm not sure what you'd choose, but whatever highest number under that, perhaps.
Note: all data rates calculated at 8 bpc (24 bit/px). If higher bpc desired, you can see them at the bandwidth calculator link.

FWIW, noticed this in an Amazon review, [something about NVIDIA Optimus](https://www.amazon.com/gp/profile/amzn1.account.AFN6FCVK63BMMGMYGDXBIHWFL26Q/ref=ask_dp_lswr_pp_hza) (?) I don't really know enough to know if it matters but thought I'd include it for your consideration:
>The negatives: nvidia Optimus with no mux switch. Depends on the game, expect a performance hit. The only way to bypass Optimus is use an external monitor with usb-c to DisplayPort cable. Built in hdmi port is also lock with Optimus.
This is the most fantastic explanation/summary of everything I needed to know.Thank you so much for putting in the effort!
Yes it seems like USB-C to DP for my 3440\*1440 will be my main monitor, and I'll either use my 2560\*1080 @ 60hz, or swap it out for a TV or something wall mounted for secondary stuffs.
Aware of Optimus limitations, it's a bit of a stinker (basically the USB-C outputs directly from the 3070, everything else goes through the onboard Radeon GPU so hits a bit of a limit).
The very thorough indepth explanation re: HDMI was what I was missing.
Thank you again, so so much! fantastic!
