5,000 pixels per inch, beyond 8K and 15,000 nits: Samsung's new OLED for VR headsets sounds completely bananas.  There's a slightly lower res 20,000 nit version, too.

Forget about your feeble 140 DPI, 1,000 nit, 4K OLED monitors, Samsung has just announced a new OLED panel with 5,000 pixels per inch capable of 15,000 nits and beyond 8K resolution. Oh, and it measures just 1.4 inches across.

It is, of course, aimed at VR headsets, hence the teensy proportions. Samsung says it will also run at up to 120 Hz and hit 99% of the DCI-P3 gamut. If that's not enough for you, Samsung is also doing a 20,000 nit version, albeit that panel only delivers 4,200 DPI.

These really bright nit levels are desirable because they'll enable a more convincing rendition of being outdoors in the real world. The beyond-8K bit means that the screen door effect or the viewer's ability to discern the underlying pixel grid should be minimised, perhaps fully neutralised, which again will only boost realism.
