Apple TV 4K won't display on LG TV (Q60R) tried different HDMI ports/cables - no luck

Greetings,

Never had this problem with my other TVs (all Samsung) with any Apple TVs.

I just got a Apple TV 4K 3rd GEN, & attached to HDMI Port #2 on my LG TV, but get no display output,

on this TV I have a Spectrum Receiver attached to the same TV on HDMI Port #1 & never had a problem

with this setup.

With my other TVs (Samsung) I've got attached Apple TVs (a year or two older than the new one) & never

had a problem viewing content from the Apple TV.

I had no problem setting up & viewing the new Apple TV 4k on my Samsungs, I even swapped out HDMI cables with the new Apple TV on the LG TV (again, no luck)

In short, I can view output from any Apple TV on Samsung, I just can't view on the LG (with any HDMI cable or any HDMI port).

This new Apple TV 4K is new right out of the box, I've got a new Monster 8K 48 Gbs cable, just seems something with the LG is prohibiting the display output, there aren't many settings to adjust.

Just wondering if anyone out there in the Apple TV world had dealt with this.

Thanks
