I have not noticed any image retention ... I'm assuming your using "retention" relative to leaving the same image (never changing) over long periods of time?  If not, and you mean the images pixel rate is not fast enough leaving a "ghosting" affect ... then I haven't noticed that either.

I read in 4k forum that OLED TVs have image retention issue or burn-in, they were talking about (like you said) leaving the same image over long periods of time, like a ghost. Good to know you did not notice anything like that. 

As for scaling, I know what you are talking about but I still need to understand how it works and how I can apply it to P3D. Are there any links I can visit to read more about scaling and how it could be used for sim flying? A bit confusing. 

Surround works for me but I don't like fish-eye effect (distortions or whatever people call it) on side monitors  really annoying, everything is stretchered out, and when I run P3D in surround fps drops by almost 30-50%. So for this reason I started considering moving to TV.  

 

Thanks again Rob. 

I'm pretty diligent about not leaving my TVs/Monitors on when there is a close to static image present for long periods ... so I may not be the best "worst case" source for burn-in.

When working with scaling it's difficult to demonstrate and really requires both external recording and internal recording to get a good understanding of what it does and it's implications.

There is thread discussion of 3 monitor fish-eye correction, be sure to follow it to it's conclusion including links to LM's posts: 

 

But my understanding is "some" native support in nVidia 1080 or higher GPUs, but I haven't experimented with it.  Hopefully those with more 3 monitor experience will chime in.

More pixels = lower FPS, how much lower will depend on the GPU used.

Cheers, Rob.

So OLED does indeed look significantly better in every test I tossed at it ... 5-30 yrs potential life is enough for us, so I'll change my original recommendation and say go with current crop of OLED TVs.

Yep, my wife and I went with OLED for the living room back in January, but we chose the 65" LG C7.  Couldn't be happier with all the 4k HD content we watch.  Streaming content from Amazon Prime and Netflix has revealed a whole new world of rich blacks and vivid, natural colors... and a reach-out-and-touch sharpness that wows the senses.  OLED technology is great!

As someone who has had an OLED TV for 16 months perhaps I can add to the discussion about burn-in / image retention.

Prior to my OLED I had a Panasonic plasma display for 11 years. In all that time it never had any image retention or burn-in issues. It was ISF-calibrated so contrast, colour and brightness were at optimum levels. I watched sport and news channels with a bright ticker bar and it never left any retention either on the plasma or now with the OLED.

It's very important that when you turn off an OLED TV it enters its compensation cycle. My Loewe Bild 7 has a LED that changes to blue when this happens and it should be left to run its course. Usually takes 20-30 mins. If you turn the TV off at the wall you're risking burn-in as this compensation cycle won't start and is critical to its long-term life.

OLEDs produce superb black levels which may be important if you do a lot of night-flying. If not, I wouldn't bother as the premium is quite high. Also, the smallest screen size is 55".

Can you clarify this one more time please? I did not quite understood compensation cycle. if you need to turn TV off or leave it ON..

Thanks

Hi Edward,

I’ve just finished watching TV for the evening so your question is well timed. I turn off the TV using the remote. That is important. Power is still supplied and the brains of the TV works out if it’s been on for more than 5 hours.

If it has that requires the display to be ‘cleaned’. You don’t see what’s happening because the screen is off but internally a process is running that cleans the panel of any image retention. It takes 20 mins or so. The LED on the front shows it’s running the cleaning process. Once finished the LED changes to white.

Don’t be tempted to buy shop-used OLED TVs as the staff generally turn them off at the mains power and then don’t go through this compensation cycle. That will result in retention or maybe burn.

The process runs most evenings but it’s automatic so you don’t have to think whether to do it or not. The TV decides.

Oh, I see. So basically not to unplug TV cable from the wall, right? 

I "think" Ray's reference is the "calibration" process that most OLED TV's will go thru after XXXX number of hours of use ... since LEPs/PLEDs are organic.  OLED is still evolving but there has been considerable improvements since they first came onto the mass market scene (around 2013/14).

On a side note, OLED response times are considerably faster than LCDs ... over 200 times faster so in theory one should be able to run extremely high refresh rates with OLED provided sufficient cabling bandwidth (which is the current limiting factor).

OLED is actually less complex and uses less power and cheaper in material costs than LCDs, but it's "relatively" new technology and hence price premium.  But I would expect LEDs to eventually be replaced or phased out by OLED for just about every monitor/TV within the next couple of years at a much lower cost than LCD.

Cheers, Rob.

Correct.

It is Rob although I chose not to use that word as it may be confused with calibration of the screen to optimise brightness, contrast, colour and gamma.

The 65" LG C7 OLED has a 'Pixel Refresher' function and 'Screen Shift' settings. 'Pixel Refresher' is the function that will clear any image retention or other screen issues that can happen when the TV is left turn on for a long period of time (which we never do, anyway). According to the manual, this function needs at least one hour to run and will only start once the TV is turned off. This is supposed to  take care of any image retention. The 'Screen Shift' is a feature that will slightly move the screen at regular intervals to prevent image retention. I did enable this feature, just to be on the safe side.

We owned a Panasonic plasma for the past 10 years and never experienced any burn-in, but our TV watching habits are fairly conservative.  I don't expect we'll have any issues with the LG either.

Agreed 100%.  I did the same thing as you Rob with the OLED.  I actually bought it for the FlightSim but my wife is a huge movie fan and I am destined to watch a lot of movies at home so I switched it to our main TV.  I now use a Visio LED and the difference is night and day.  Especially at night.  The OLED will blow you away if you are fortunate to get one for your sim monitor.  Now 3 65 inch OLED's at 4k would probably be the 2018 holy grail of surround visuals in my mind.

Until 8K OLEDs become more main stream :) ... progress, gotta love it.  I think OLED will become the "standard" in the near future, heck even my iPhone X is OLED.  For simulation and gaming the difference is rather dramatic especially for night flights as there is no "light bleed" or "shades of black" and the lights have an entirely different intensity about them and it makes the good lighting system in the cockpit come alive. 

I've been skeptical about OLED and somewhat resistant, but I've certainly become a "believer" in OLED (ironically I have to thank my wife for that) and it's value moving forward ... the prices will drop, it's inevitable.

Cheers, Rob.

You think 8k will add anything to sitting two feet away in a simulator? I feel like 4k has added very little to my normal TV viewing experience sitting on my couch 10 feet away but it's a solid improvement in the Sim. I think what 4k was to 1080p TV is what 8k would be to the Sim.  Now 8k VR I can see making the world a better place.
