![]() OLED PenTile displays, on the other hand, only have 2 subpixels for each pixel (a dedicated green subpixel and 0.5 red and 0.5 blue pixels – the other half is shared with neighbor pixel). LCD displays with RGB Stripe layout have 3 subpixels for each pixel (red, green, blue). One of the main differences between LCD (RGB) and OLED (PenTile) is the subpixel count and layout. If you want to know the basic work principles of LCD and OLED displays, I personally found this article to be helpful. With the current technology, these two are the most suitable for consumer VR headsets (in terms of cost vs quality & tradeoffs). Image source: WikipediaĪs a very broad and generalizing statement, we can say that most of the current VR headsets utilize two main categories of displays – LCD (RGB stripe subpixel arrangement) and OLED (PenTile subpixel arrangement) To also compare and put the resolutions of different VR headsets in perspective, I found the following chart to be useful. Do keep in mind, that this is a macro shot that greatly amplifies the pixelation and screen-door effect.Īs a general rule, we can say that more pixels equals a sharper and more defined image (but this is not always the case, as we will find out later). We can see that the dials are clear and easily readable for Pimax 8K X (8.3M pixels), whereas for the first-gen HTC Vive Headset (1.3M pixels) it is just a blur. To illustrate my point, have a look at the through-the-lens macro captures of Aerofly FS2 flight simulator cockpit dials. The Importance of Resolution – Source: SweViver In general, the more pixels we have for a specific area (which with VR is the field of view), the sharper the overall image will be. ![]() When we multiply the pixels in the horizontal and vertical axis, we get the total pixel count. ![]() The Oculus Quest, for example, has 1440 horizontal and 1600 vertical pixels (for each eye) The basic idea of resolution is simple – it shows how many pixels the display is able to output in the horizontal and vertical axis. ![]() If you are using a mobile device, make sure to put in landscape orientation for an optimal viewing experience! HEADSET RESOLUTION (PER EYE) PIXELS ( ?) DISPLAY TYPE ( ?) SUBPIXELS ( ?) HOR FOV ( ?) PIXELS / ° ( ?) Pimak 8K X 3840 x 2160 The VR headset with the highest resolution is currently the Pimax 8K X which is able to output a native resolution of 3840 x 2160 per eye.Ĭlick on the “(?)” link in the table header, to navigate to the explanation part of this particular metric – how I got it and why it is important to consider when evaluating a VR headset display. In the table below, you will find all the most well-known VR headsets as of April 2020, ranked by resolution (total pixel count). But please do take the information with a grain of salt. This article is an attempt to summarize my learnings. Instead, I am just a curious mind who wanted to understand the visual side of VR a bit better. In this article, we are going to explore why resolution alone, although important, does not really paint the whole picture about a VR headset’s expected visual properties and why it is (more) important to also consider the display type, subpixel count and pixel density, among other factors.ĭisclaimer: I am far from being a display and optics experts. ![]() You might say it’s the car world equivalent of “How many horsepowers does your vehicle have”? For many people, VR headset display resolution is one of the most important specifications when evaluating and comparing headsets. ![]()
