usb c display port not working

[leshchenko]

I faced an issue in that the type-c display port doesn't work on my laptop gigabyte g5 kd.

After clean install Windows 10x64, updating all drivers from the official site, and from the Intel site using driver assistance issue persists.

It works fine with the same cable with my macbook.

Windows 10 Pro Version 22H2

Please help me.

UPDATE:

1. Bios was updated to the latest one from the official site - FB05

2. Official gigabyte support say it's windows issue, and need to make clean installation. But it doesn't help.

When I tried to do clean windows install and updated all drivers from the official site, I faced next problem.

Prerequisites:

1. My laptop is turned on

2. Monitor is plugged into the laptop by a type-c display port

Steps to reproduce:

1. Download serial io driver from the official site.

2. Start and install it.

Right after installing the screen blinks, the Windows sound of the new connected device plays, and the external display start working. If I unplug the monitor, then plug in it again, it doesn't work again. After doing all steps again, it starts working until restarting/turning off the laptop, and unplugging/plugging in the monitor. By the way, the monitor is working fine with my Macbook.

So I came to the conclusion, that it's the software problem, as it works fine after driver installation.

Have you updated your gigabyte bios?

Have you contact gigabyte to see if there is a hardware issue?

Do those first, and then come back if there is still a problem.

I am curious: Why are you inserting the SerialIO driver as a variable in this issue? It has nothing to do with Thunderbolt support.

Since this is a laptop, you should not be loading any drivers from the Intel site. You should only be installing and using only the drivers that are provided by Gigabyte.

Just saying,

I just installed all drivers from the official site and tried them one by one hoping it will help. And it started to work after installing the serial io driver. I just described what I saw.

[n_scott_pearson]

'Official site', as in that for your laptop vendor? Unless your vendor tells you otherwise, you shouldn't be using any of the generic drivers from the Intel site (especially with laptops). The vendor often has customizations that are specific to the laptop design and replacing them with the generic drivers from the Intel site could remove capabilities or affect stability.

[leshchenko]

Yes, "official site" means "support" section with all drivers for my laptop on the vendor website.

Got you, so this issue can be done only by vendor. Will wait for the response from their side.
