Hi,
I've had this problem ongoing for a while, thought I'd ask here incase anyone's seen it.
While I'm overall really happy with my Zephyrus, there's a weird problem with the HDMI output. While connected to my Panasonic 4K TV, I'm not able to get the laptop to output picture to the display when selecting 4k (3840x2160) resolution at 60hz. The option appears in the menu as selectable, and it appears as if the laptop believes it's been set (I can move the cursor off the laptops panel when in 'Extend' mode), but the TV shows a 'no input' message. 4K 30hz is also selectable, and this works fine, so it's as if the output is stuck at HDMI v1.4 for some reason.
I know the TV itself is working fine, as I've had no issue running at 4K 60hz on my desktop PC, and I've used the same HDMI cable with the laptop. I'm curious as to whether there's a particular driver which is incorrectly installed or something? I have re-installed Windows 10 since I purchased the machine and this didn't resolve the issue.
Any assistance is greatly appreciated.
