Mini M4 and LG OLED TV as a monitor?

I know there are a quite few Apple folks roaming this forum. Are any of you using the new $550 Mac Mini M4 with an OLED TV as the monitor? I just read through this thread:

and if I understand that correctly, the Mini M4 should work with the 4k OLED TV (link below) via HDMI 2.1, however HiDPI scaling is not supported. Coming from Windows PC's I'm not sure how to draw a parallel to what I might be missing in the absence of HiDPI. I'm really just looking to run one of the new M4 Mini's with 4k resolution @ 120hz on OLED.

What would you recommend for a monitor otherwise?
