Question about Pimax 8K

As far as I know, the 8k glasses are unfortunately not available with OLED. I think CLPL is simply a marketing term invented by Pimax that you don't need to concern yourself with any further. I would simply look at a few reviews on the net to get an impression of the glasses. In short - contrast, black levels etc. per se are not as good as with OLED glasses, but the resolution and especially the field of view are awesome.

Two tips:
1) To really get the 2x4k resolution you have to buy the 8kX glasses, the 8k is upscaled.
2) The Pimax products are enthusiast glasses and you have to deal with them a bit. If you don't want that - Valve Index or HP G2 Reverb have a much more user friendly experience with great built-in displays (but not with the field of view of the Pimax glasses).

Oh yes, absolutely, it's not witchcraft at all :). It just takes a bit of time that you spend googling and reading forums instead of playing, for example to find out with which settings you should play a certain game with the Pimax.

Another important thing to know: Pimax only comes with the glasses, you still need lighthouses and controllers. And a powerful graphics card is needed to push so many pixels. Have fun!
