    That's some nice revisionism you've got there but I'm happy to indulge it if that means you'll stop strawmanning my positions ;)

    On the topic of motion blur, the article mentions a higher framerate severely reduces it so that's an incentive for developers to make 60fps games :p

    If their conclusions don't agree with your preconceptions they're not to be trusted, empirical evidence be damned. Very reasonable.

    4000:1 is a very low contrast ratio there is nothing to hype about that. Such contrast rates weren't special even 10 years ago. I also own measuring instruments myself and their measured results are often wrong. No specialist knowledge (set the TV incorrectly etc.) or good equipment seems to be available. They measured e.g. 0.011cd/m2 where many experts and I always measured something like 0.004 to 0,005cd/m2. That is already a gigantic deviation.

    Is that native or dynamic contrast ratios?

    VA panels should be typically above 4000, I think. Not TN or IPS though.

    An OLED will have basically zero ghosting caused by pixel transitions, but they are sample/hold displays so they have motion blur just like LCD. Some OLED tvs can do black frame insertion to reduce motion blur, but they're typically already low brightness displays, so it's a larger compromise than on an LCD that has BFI or backlight strobing. But LCDs more commonly suffer from ghosting, because of slower pixel transitions, especially VA panels which are typically the type found in TVs. TN panels have the least ghosting, but they have terrible contrast and colour accuracy. IPS panels have great colour accuracy, and can have fast responses for low ghosting, but they have garbage contrast.

    It's fairly common to see native contrast over 5500:1 now. The "stopgap" TCL P607 I bought last year was measured at 6437:1, which is oddly much higher than this year's model.

    Edit: Changed number down from 6000:1 to actually be in the "fairly common" range.

    According to the article the perceived contrast ratio depends on ambient lighting. In perfect darkness (or very cloe to that) OLEDs win but with some ambient lighting that changes in favor of LCD displays.

    Contrast may increase with LCDs in brighter lighting, but in dark shots, you still get ambient reflections ruining it, so you decrease room brightness to see the film/game in all its glory - same as cinema (which has lousy contrast ratio!). The article is about displays in all their uses - for gaming, we can ignore various benefits like flexibility of screens.

    There's bias lighting in which no reflections are added since the lighting is positioned behind the screen.
