Hello
@djdragon737,
Because you have the i9-9900KF, it means there is no iGPU. Therefore, in order to connect a Thunderbolt monitor (like LG UltraFine 4K or 5K) to the Designare, we have to route one DisplayPort cable from the AMD GPU (Radeon VII) to the DP-In port on the rear IO panel. Then the Thunderbolt port closest to the HDMI connector will work.
Because this motherboard has only
one DP-In port, it means only
one Thunderbolt port will work. However, if you replace your CPU with i9-9900K (not F) or i7-9700K then iGPU will work with
both Thunderbolt ports. In fact, with iGPU we get these options:
Option 1:
- TB port 1 --> iGPU
- TB port 2 --> iGPU
- DP-In --> not connected
Option 2:
- TB port 1 --> AMD GPU
- TB port 2 --> iGPU
- DP-In --> connected to AMD GPU
But if there is no IGPU then there is only one option:
- TB port 1 --> AMD GPU
- TB port 2 --> (no video)
- DP-In --> connected to AMD GPU
However, you can buy either Gigabyte GC-Alpine Ridge or GC-Titan Ridge to add two more Thunderbolt ports. These add-in-card contain additional DP-In ports, so your Radeon VII can connect there as well.
By the way I'm unable to find information on 32UL350W. Is that an LG model? Is the model number correct?
P.S. Are you an aviation fan or work in aviation? By any chance are you working to fix the 737 MAX?
