Works with most displayport/hdmi adapters with 2 screw positions. I mounted 2x ADT-Link P6A-P8T-BL 0.15m cables. I only found this 2 positions working with 2 GPU in the lowest position. The pictures will explain what I mean. I got the confirmation that the HDMI ADT-Link cables also work.

You need 2 cables and the correct screws for it. The ADT-Link cables need m4 5-10mm screws and can handle 3440x1440 120hz.

I didn't test this in the normal 3 slot configuration of the Meshi. I was using the vert/horz version in the 4 slot gpu config and a stand-off riser mod. Now i am using the horz horz version with a 3080ti FE card in the highest position and 3slot mode of the case and stand-off riser mod.

He also mentioned antoher important thing regarding the cables:

"The suggested cables work great but will require an active adapter if you want to convert from DisplayPort to something else (for example I need HDMI when connecting to my TV). This is mentioned on the product page and I have now confirmed, and active adapter bypasses that issue." Reddit u/TheMeanCanEHdian
