I've read several times that 4K below 50" screens is a waste of money.
One just can't see a significant difference
If you want a top quality TV below 50 inches - which I do - the necessity to buy a £50 Fire stick or a Roku to go with it is hardly a show stopper - even if I didn't have one already.I was very surprised and disappointed to read that this TV does not support the standard suite of catch-up apps. As far as I'm concerned this would be a show stopper. I cannot comprehend any manufacturer these days, introducing a new model without this facility. The review made no mention of any intention by LG to correct this error via a future software update.
In case this helps anyone considering this TV- I returned my CX48 after a couple of weeks for a refund. I seem to be highly aware of motion processing and even with it all turned off, live action motion felt artificial and ‘electronic’ rather than natural and ‘optical’.
I then tried a Sony 55” A8 in-store with all motion processing off and motion was rougher with panning shots but more natural overall. This suggests LG in their wisdom don’t let you defeat as much motion processing as Sony and What Hi Fi do give Sony the edge here. The effect for me was so bad with the LG I was ‘seeing’ the acting, the magic had gone. YMMV
Reverting to my 2005 43” Pioneer plasma was a relief and I didn’t miss the LG other than its HDR and true blacks. . However the picture is so photographic with the plasma that I soon forget and just enjoy the content.
Now awaiting Sony’s 48” A9 which drops soon.
And you could sit closer and thus benefit from the improved image.4K is just pixel resolution, and yes beyond a certain viewing distance a smaller screen may not yield much improvement here over HD. But HDR and dynamic metadata (which are common in 4K formats like DV etc) mean smaller sized 4k screens still produce a picture with a deeper and more realistic contrast ratio than a similarly sized HD screen. You could argue in fact that a smaller screen’s increased pixel density gives it the advantage here over biggerTVs.
