TS4, G9 57" and PBP

Hi,

I'm running into issues with TS4 and G9 57" and PBP.

2 cables are connected using 8K USB-C to HDMI on TS4. I can only get one at 4K 60Hz and the other is stuck at 30Hz. I just got got the TS4 and everything is up to date (firmware and power delivery).

When the screen is split 21:9 and 11:9; the smaller screen resolution is messed up and can't be configured to the right scale.

This is quite frustrating for a C$500 dock. Spent hours troubleshooting and it just won't work.

Please advise.

EDIT: issue turned out to be the USB-C HDMI adaptors even though I bought a higher end one. Cheaper ones arrived today and they work just fine.

Hi OP u/Hafezberg I'm having major issues with this exact setup (except I'm using TS3). Here's a post I made on it . Would you be willing to share the specifics of the adapters and cables you are using from the Caldigit?

You don't have any noticeable difference in refresh rate or colors now between the two screens?

Use hdmi for both inputs and it will work fine. I had the exact same issue with the hdmi/do combo. Switching both to hdmi solved it.

Unfortunately I did still have the same issue with both on HDMI, but I haven’t updated the firmware on the adapters as advised in some threads I found yet (waiting to use a friend’s windows computer). Did you update the asapter firmware to get this working? And it seems that a specific adapter solved the problem for you based on your original post, which one was it?

This is the pair that worked for me:

Thanks! Just to be clear - using these you have zero tearing whatsoever? In my current setup it's not super noticeable but it's definitely there: link

That’s bad. I don’t have this at all. I think that’s caused by low refresh rate. I’m running both screens at 60Hz.

Thanks for the response!

To clarify, this is only for windows that stretch across the middle “seam” of the PBP monitor. You need to turn off the setting “displays have separate spaces”. You’re doing that and still not getting any issues while scrolling at the middle where the screens join?

This is not happening within each individual screen - and I’m at currently at 120hz for each screen

Ah - I don’t need to span a single window to 2 screens. I’m doing 2/3 and 1/3 PBP as it works best for sharing the smaller screen on MS Teams as I’m pretty much online all day.
