The C4 is amazing. The picture quality over my previous LED tv is amazing. Gaming on it is also a step up. With the VRR, auto low latency and 4K 120hz display games feel smooth and look great. The TV also supports 144hz pc mode which I haven’t tried yet as I have a separate oled monitor.To get the picture settings just right, I watched an easy to follow YouTube guide.The C4 may not be as bright as the G4 but at almost £800 more at time of purchase, ignorance is bliss.The TV also supports Apple HomeKit and allows me to turn off the TV or change input from my phone. Not amazingly useful but I’ve used it a couple of times to turn the TV off when the kids have left it on.One thing I have noticed when using the Apple TV, I can now control the volume on the TV when using my phone. Not sure if this is a coincidence of an update but I’ll add it to another growing list of why this was a good purchase.Overall, I’m really happy with this TV and even my wife has admitted the picture quality is great. This is the ultimate seal of approval for me and justifies my purchase.

Excellent TV. Colour is outstanding – installers said this model has the best colour of any TV . W-fi and apps installed really quickly. LV Channels includes CNN for free so very pleased with that. Watching Wimbledon on BBC1 HD right now – brilliant. Best I’ve seen for getting rid of motion blur. Superfast response from the remote which also looks very funky.

Had it for two weeks but sent it back to manufacturer mostly because of short warranty of 1 year but here are a few thoughts after having lived with it for a few weeks;It is true that OLED need a few hours of settling down, in my case about 2 weeks, perhaps 30 or so hours. Prior to that colours seem a little off as is shadow detail. So the following impressions are post the above;The good;Packaging. Minimal and easy to open/re-pack. Environmental friendly with no colour box printing.Build quality is excellent. The set exudes a sense of quality. Although mostly plastics, they are well made. The screen has a very slim metal surround and the stand is mostly metal too. Solid. Very slim which is great for wall mounting if required (wall mount not supplied).Reflection handling is outstanding despite a glossy screen. LG really have figured this out. Samsung have in the meantime released flag ship tv’s with matte screens which, in my opinion, look horrible and instead of giving slight reflections as with the LG, make the whole screen look washed out and purple grey in lit environments.Picture quality. Outstanding contrast (OLED) in both bright and dark scenes in SRD. Brightness is more than adequate for even bright rooms. HDR is simply superb though I have to turn everything down as it was simply too bright. Some may like this. Even with my much subdued HDR settings they pop off the screen and really are a sight to behold. Colours are true to life once calibrated to my liking which also meant a slight reduction in the colour settings*.The bad;The R/C. Too many buttons too close together. I continuously press double or just the wrong ones. Plastic and not rechargeable. Not back lit. Samsung’s are far ahead. C’mon LG, surely you can do better. The pointer option is just annoying.*Colour volume. Whilst it can produce gorgeous colours (see above) the colour volume is not quite up to Samsung’s Quantum Dot TV’s (as my 5 year old Samsung QLED). This shows in minor colour gradation and is only really visible in direct comparison where Samsung can show slightly more gradation. I am talking minor differences but they are definitively there.White’s; In maximum brightness settings in settings other than Expert Pro dark/bright and Cinema setting white’s can exhibit a blue tint. By adjusting colour temperature to a warmer setting this can be mostly mitigated. However, for me, the much praised warm -50 settings look too dull and warm. I found warm -20 ideal, striking a good balance. Viewed off angle, whites can have a slight green tint.Operating system speed. My 5 year old Samsung seemed faster to navigate. No big issue but there is always slight hesitancy in operation.Not sure;LG operating system. Perhaps it’s because I am not used to it but I prefer Tizen or/and Google. When I tried to instal Nord VPN on the LG (to access Discovery + Germany … long story) I lost my will to live and abandoned the idea.Fazit;A superb if not perfect TV. If you like to watch sports in super bright (and super bright rooms) this may not be for you and perhaps mini LED or the higher end, brighter OLED’s would be a better option. For many though, this is a lovely product if you can live with a few quirks and most TV’s seem to have some if Forum feedback is to be believed.Be careful where you order this set from though. Warranty differs wildly, from one year (manufacturer) to 5 or 6. To get an additional 3 year warranty from manufacturer will cost you almost £200 which makes even the discounted price less competitive.The new C5 is out now but I have not tried that one

no need for a review. I’m sure you can find a lot of it in you tube.I have the same OLED in another room. I bought again the same… LG OLEDs are the best.
