JSAUX FlipGo 16" - Bottom display (Lower) not detected after update, only Upper works

[1GMedia]

Issue

After updating BetterDisplay, my JSAUX FlipGo 16" dual display only detects the top (Upper) display. The bottom (Lower) display remains frozen/black.

Setup

• JSAUX FlipGo 16" DuoViews connected via HDMI + USB-C
• macOS (latest)
• BetterDisplay (latest version after recent update)

What worked before

• Both displays worked independently
• Connected HDMI first, then USB-C
• BetterDisplay detected both "Upper" and "Lower" displays

Current problem

• Only "FlipGo 16" DuoViews Upper" appears in BetterDisplay
• Bottom display stays frozen/black
• Settings show Display:5 (Lower) configuration exists but display not detected

Debug info

BetterDisplay has these settings but only Upper is detected:

• Display:4 = "FlipGo 16" DuoViews Upper"
• Display:5 = "FlipGo 16" DuoViews Lower"

Without DisplayLink drivers, this worked via BetterDisplay before the update.

Hmm. I think there might be a confusion. On Mac the upper/lower separation works with DisplayLink only I think (using the DisplayLink USB-C port of the FlipGo 16"), as Macs simply do not support MST (at low level and BetterDisplay does not change that) which is required to DisplayPort carry separate video for multiple displays (with HDMI it should not work at all even on PC). Or you say your FlipGo Pro 16" provided two separate displays when used both HDMI and the non-DisplayLink USB-C/DisplayPort ports?
