Radeon Pro 5xx cannot adjust overscan in Windows 10

hi all. I'v just install a brand new Windows 10 in a new MacBook Pro 15" 2017 using Boot Camp.

Now I have a issue about the extended display, I connect the MacBook Pro to a external TV (LG TV) as a second display. But there is a serious overscan in the TV, and I cannot find how to adjust overscan/underscan in the Radeon Software settings. Also, there is no place in the TV settings to scale the screen.

As you can see from the picture a attached, there is no place to adjust the overscan/underscan or HDMI scaling.

What should I do? Thanks.

In macOS, everything is fine. The TV can be recognized and overscan / underscan can be adjusted smoothly.

I don't think it's a USB-C adapter problem, it's the Radeon Software, which somehow hide the scaling setting to somewhere. I went through the AMD technical forum, a lot of other people have the same issue.

If you switch to macOS with the same connection topology, is the TV detected as a television? Are you allowed you to change the overscan/underscan settings? The USBc adapter can cause issues.

You answer may come from the AMD forum. One thing you can try, are the drivers from bootcampdrivers.com.

To clarify, is the LG TV connected to the Mac via HDMI?

Yes, via a USB-C adapter. HDMI to HDMI cable.

I tried the bootcampdrivers.com, but after read the Read Me documentation, the installation process is way too complicated, I'm afraid it gonna mess up my system. I guess I'm stuck here.

I have read this article from AMD, and this is exactly the issue: the HDMI scaling slider bar is not there! As you can see from the picture I attached.

Why the HDMI scaling slider bar is missing in the Radeon Software. I installed the latest driver, no doubt.

Even though your screen does not show it, the standard method is How to Resize an Image to Fit the Screen of an HDMI Display .
