LG 48CX OLED - 4K 120 Hz

I'm having an issue with 5.1 audio from PC so thought I'd post to see if anyone has the same.

3080 in PC connected via HDMI 2.1 to LG CX port 1.
TV connected to Marantz 7012 receiver via ARC.
Receiver does not support HDMI 2.1 but does support EARC

With out of the box TV settings, Windows 10 only shows stereo as an available format.

I've fixed this by using these TV settings:
Sound-->Sound Out-->"HDMI ARC"
Sound-->Additional Settings-->HDMI Inout Audio Format-->HDMI 1-->"Bitstream"
Sound-->Additional Settings-->Digital Sound Out-->"Pass Through"
Sound-->Additional Settings-->eARC-->ON

Windows now shows 5.1 and 7.1 available.

The issue is that I have a 5.1 set up but Windows keep switching to 7.1. automatically which messes up the surround levels (presumably because my surrounds are getting surround + rear surround signals sent to them)

I'm not sure if this is a TV or Windows issue. Anyone else experiencing this?

Another weird thing I found is that in the Windows sound settings where you can play test sounds to channels, in 5.1 the sound for front right and rear right are swapped over. Yet when playing dolby sound tests the channels are correct.
 
I've seen a few videos of people raving about this oled screen, and the fact that it can sync to gpu is making this attractive to me. Its been so long since I used (crt like) screen is it different to lcd so you can have any resolution and it wont look terrible because its not the specific res of the monitor? And the reviewer I saw mention you cant use it as a main screen because of burn in?

In my limited experience, modern TVs are brilliant at upscaling - I'd guess it's as they're designed to deal with low res tv signals day to day. I've been using an LG 55" C9 at 1440p and I can barely notice the lower resolution at a comfortable viewing distance.

In terms of burn in, you do have to be careful but it's not a deal breaker - use dark windows themes, don't play the same game constantly for hours on end, that sort of thing. I wouldn't use it for office sort of stuff, but for gaming where the picture is constantly changing it'll be fine.

The burn-in is a big debate I am not covering it here, I use my CX 55 for the main pc monitor, you can have any resolution but if your thinking of running it @ 1080p you will not get any vibrant colours, deeper blacks, brighter whites, and sharper images more then a LCD and 1080 is only 2k and it would look terrible IMO this OLED was design for 4k HDR, And you must change your content if you run it for 15hours a day on one game you will get a risk of a burn in

The 55CX is actually cheaper than the 48CX in some places, are there any downsides to the bigger panel?

there is no differences between a CX48-CX55 in gaming the CX 55 PPI is 80 CX48 is 92 PPI;)

I'm going to be playing some racing sims, Project Cars etc. Now, normally I disable all HUD elements and I actually think it adds to the immersion but with a racing sim it's not really viable.

Do any of you play these type of games on your OLED, and if so what would you say was the maximum time for a session to avoid burn in risk?
 
I don't play any racing games, I play Anno 1800 and Valhalla, Odyssey, Origins, Watch dogs legion, and I watch Netflix & Amazon I always mix my content for 12 hours a day:D

You just reminded me of one of those Amazon Q&As...

Does this washing machine do 1400rpm spin

"I don't know, we decided to buy a kettle with our voucher instead"

:p
 
OLED burn is mostly cumulative, not per session.
1 hour per day for a year should have the same impact as 365 hours straight (although heat is a factor).

Looking at the burn-in tests if you stay at a sensible OLED light level there should be no issues for the first 2-3000 hours.

A dark windows theme is possibly the wrong way to go. You now have bright white text burning into the set instead of a large area of more evenly lit pixels.

You ask a question of burn-in and I gave you the answer 12hours if you want to play more hours your choice:p

That's really interesting, I had no idea it was cumulative. I had it in my head that if I changed the pixels by changing the content then it would essentially reset the area. If it's cumulative then there's no point in even bothering with it, the anti burn facility will either do it's job or it won't.

Edit: actually, I would say my normal use is around 3hrs per day so the first 3000 hours would be around 3 years for me. I think I might be concerned over nothing with the burn in risk.
 
Don't forget to hid the Taskbar and bin, Then one company Rings.com only colour testing reports a burn-in on three year old OLED TV's risk the end of all OLEDs on the market and then media spread the propaganda to make things worst then it hit the forums in a big debate over who can see it and those who can't after 2 years then in 2020 the CX hit's the market and insurance companies rush out on burn-in covers to sale the public at JL then after 2 years the Burn-in insurance cover run out and they raise the cover prices again for another two years just in case you get a risk of a burn in

So to be safe why don't we all only use the OLED for one hour a day just in case we risk a burn-in, then at night unplug it and put cover over it to keep it safe after all it's a glossy screen!
:D:D:D
