LG CX screen resolution?.

Hi, I have recently bought an LG CX tv and would like to know is there a way of knowing what screen resolution the tv is running at any given time!?...

@colin lawson I think the only (very basic) information is given from the "i" info button on the remote, like HD or SD for any given programme.

This is further "muddied" by the fact that HD can mean 720 or 1080. Here are no "apps" that can show this while a programme is being watched, but personally I think there should be more "info" on the "info" screen to shows this.

Isn't the screen always running at 4k (3840x2160) ?

Lower definition feeds are upscaled to the native resolution, as far as I know

I thought the OP (@colin lawson ) was asking how to tell what the actual broadcast signal was, before being upscaled and displayed, so sorry if I confused things.
Certainly a 4K TV will, as you say, upscale to "fill the screen" pixels from the lower resolution source. But, on some sets, SD can look awful, unless at a distance away (say 9 to 10 feet).

Given that some channels on Freeview/Sky/Foxtel are still only using SD (and even on "HD" channels, I think SOME older stuff still goes ou at SD) , have a read of this quote from :

"Perhaps the biggest problem with 4K is upscaling. Upscaling means taking something of a lower resolution (like 480p DVD) and stretching it out to fit on higher resolution display. All 4K TVs upscale, obviously. However, not all of them do it very well. Poorly upscaled content can look grainy and soft with jagged edge and loss of detail. Even older standard definition can look just plain bad no matter what 4K TV you buy."
