LG is showing off the world's largest and highest resolution OLED panel in an 88-inch TV at the Consumer Electronics Show:

Just as 4K and HDR are finally going mainstream, the ambitious folks at LG Display have also been busy pushing its OLED technology to 8K. Come CES, the Korean manufacturer will be letting attendees get up close with its new 88-inch [2.2 meter] 8K OLED display (can we just call it the "Triple 8?"), which is both the largest and the highest-resolution OLED panel to date. But as far as specs go, that's all we have for now.

Also at The Verge and BGR.

    You barely need antialiasing [with 4K displays]

    Screen resolution has almost to nothing to do with anti-aliasing.

    In computer graphics, aliasing normally refers to a type of quantization error caused by rendering to a fixed pattern of pixels (in the case of a computer monitor this is a rectangular grid). It occurs when the source information does not exactly align with the pixel grid. Normally these errors are periodic and highly non-random, resulting in significant damage to the original signal (it is called "aliasing" because different signals become indistinguishable -- hence aliases). The effect is the same sort of error you see in a Moiré pattern [wikipedia.org].

    In this context, anti-aliasing is a form of dither which adds randomness to remove aliasing errors as much as possible, replacing it with a small amount of white noise. Anti-aliasing is always required for correct rendering on a fixed grid of pixels like a computer monitor -- regardless of the resolution of that pixel grid.

    Nevertheless, up to a certain point, higher resolution will look better because the noise floor from dithering will be reduced. The ~100 pixels/inch displays of yesteryear are definitely not ideal for small text so I say bring out more pixels!

    (NB: When done correctly, anti-aliasing will completely eliminate all aliasing errors (with high probability) for signals above the noise floor by the use of random sampling. However, in raster graphics it is very common to use post-processing techniques to hide visible artifacts rather than true anti-aliasing. Such techniques are sometimes confusingly called "anti-aliasing" even though these don't actually do anything to prevent aliasing!)

    You miss the point completely and are overrated.

    Anti-aliasing is always required for correct rendering on a fixed grid of pixels like a computer monitor -- regardless of the resolution of that pixel grid.

    Not if you are viewing a very high resolution grid with comparatively low resolution eyes.

    Then the limitations of your eyes will do the "anti-aliasing". No need for the grid to do any of that.
