D5 via TB2.. what about the Displayport?

[edgley]

I'm running an iMac, late 2012, with Sequoia.
The D5 is connected via the iMacs TB2 port, into an Apple TB2 to TB3 and into the D5.

Given the lower speeds of TB2, am I still going to be able to:

- add a monitor via the Displayport?
- add another monitor, via the spare TB3 port on the D5?

Thanks for any help

The speed of TB2 is relatively low. How many MB/S is it?
The speed of an HDD is about 200 MB/S, and it is related to the performance of the hard drive.
Can another monitor be added via the spare TB3 port on the D5? Generally, the monitor is connected through the DP port of the D5 device. However, it's not certain whether the 2012 Sequoia iMac supports displaying via the TB3 port.

I can confirm, using nothing more than a £5 TB3 to HDMI does power a monitor, on a 2012 iMac with the 1GB GPU.
Additional, using Opencore Legacy Patcher I am able to run, perfectly normally Sequoia with software like:
- Logic Pro
- DaVince Resolve
- Adobe

I will get a DP to HDMI converter next and see if it will take a 3rd monitor.
Not bad for a computer that's 13 years old.

I now have a 30" monitor that does 2560x1600, which has Displayport, HDMI and DVI.

If I connect it via the D5, either via the dedicated Displayport connector or using the HDMI connector (which did work when it was a HD TV) - I get no connection.

Which means the HD TV will work via the D5 but not the 30" monitor.
