Pimax 8K – The Ultimate Guide


While Oculus and HTC are currently limited to "2K" per eye (1440 x 1600 pixels) and a FOV (Field of Vision) that does not exceed 110 degrees (for the Vive Pro in particular), Pimax is convinced from the beginning that a good VR headset must have a very high definition and a FOV (Field of View) as wide as possible. After the 5K with the 5K Super and 5K XR, here is the Vision Pimax 8K X that delivers a definition of 3840 x 2160 pixels per eye, as well as a 170 degrees FOV. The screens used are of LCD type, with a refresh rate limited to 75 Hz in 4K native. In order to increase the frequency, it is therefore necessary to lower the definition.

Another version was presented and testable on the Pimax stand : the Vision 8K Plus, which also delivers UHD definition per eye, but via upscaling. Remember that upscaling consists in scaling an image to adapt it to a higher definition than its original definition. This technique, which is widely used on consoles, has the disadvantage of delivering a slightly less sharp and precise rendering than "native".

But the question you're probably asking yourself is, "so 8K in RV, does it change everything?" Well... Yes and no. The increase in definition is clearly visible and we finally arrive at a rendering where it is almost impossible to detect the pixels. The grid effect is totally invisible and the cleanliness of the image is particularly felt when approaching a character. The realism is then striking. The reading of text is also perfectly clear. In short, there is no doubt that this "Pimax 8K" rendering is the closest to reality at the moment.

But the experience is unfortunately a little spoiled by the 175-degree FOV, which is currently lacking in optimization. The lenses used have indeed a tendency to distort the image on the sides and the "magnifying glass" effect in peripheral vision ends up being unpleasant. As a result, you concentrate primarily on what is in front of you and the potential of such a large field of vision is somewhat wasted. In addition, the 75Hz blockage in native definition is felt at play, so much so that we came out of our 20 minutes of slightly nauseating demos, which hadn't happened for a long time. This is a concern that we found less on the Vision 8K Plus, as the frequency rose to 90Hz, for a rendering that was almost as good.
