I built a server with free hardware.
This is a match:
CPU: i5 3570
Motherboard: B75m-d3v
Graphics card: GTX650TI
Proxmox version: 5.3.5

There is a VT-d button on the motherboard, and I turn on the internal display. After the setup is complete, when I start the windows10 virtui machine, the gtx650ti has no signal output. I tried setting a romfile for it and changing the bios model, but it still didn't work. If this is about support issues? Can someone help me? Thank you.

Not an answer to your question, but I'm running passthrough with seabios on a win10 VM and it works like a charm.

You must also make sure that the gpu is using the vfio-pci driver.
check with lspci -nnk

Code:
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti XT [Radeon HD 7970/8970 OEM / R9 280X] [1002:6798]
        Subsystem: PC Partner Limited / Sapphire Technology Tahiti XT [Radeon HD 7970/8970 OEM / R9 280X] [174b:3001]
        Kernel driver in use: vfio-pci
        Kernel modules: radeon, amdgpu
01:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti HDMI Audio [Radeon HD 7870 XT / 7950/7970] [1002:aaa0]
        Subsystem: PC Partner Limited / Sapphire Technology Tahiti HDMI Audio [Radeon HD 7870 XT / 7950/7970] [174b:aaa0]
        Kernel driver in use: vfio-pci
        Kernel modules: snd_hda_intel

Keep on reading and continue trying.

There's been some reports that a GFX passthrough might work if you have a screen connected to the GFX so as to wake it up...
