There may be devices that act as a HDMI hub, but the closet device that would do most things I could name is an audio visual receiver. What external devices are you using though?
Not the question you asked, but is there any particular reason you want to go QLED? For a couple of hundred more than the Q60T you posted (which is way overpriced IMO), you could get a 2019 Panasonic GZ1000 OLED TV, which I would argue is far superior in picture quality to any LCD TV.
The 2019 GZ1000 does look pretty good.
Only reason for QLED was the good reviews on current year models even compared to OLED, and the price.
Dollar for dollar everything else being equal the OLED wins but for what we need an OLED doesn't justify much of a premium. We currently don't have a TV but would like to have something bigger/better than a laptop screen to watch a few things off YouTube etc.
I'd be quite happy with a 2019 model but struggled to find anyone locally with one. Also it's a bit of price creep from our top dollar, especially as it may not get a tremendous amount of use.
