If you take a solid blue object and add some partial red/green, it will get brighter and still be bluish. So you add a few bits to compensate.īack in low-dynamic-range land, designers have a choice for what to do about bright, colored objects: they can reduce the brightness (reducing their impact), or they can desaturate. If you stuck with 8 bits, then compressing to 10% means only 25 levels of brightness, which is not nearly enough. You also need a higher bit depth, since you’re using a smaller portion of your range most of the time. That would be wasteful since most of the scene won’t need it, so ideally the backlight is segmented such that most parts can remain at the normal levels. Of course, if you’ve made white be at the 10% level, then you’ll have a very dim screen unless you put in a very bright backlight. Or even white itself, as long as you limit it to small portions that would be dazzling in real life, like a flashlight. You make full white be (say) 10% of the possible brightness, but allow saturated colors to go higher. The answer to this is to allow color components that are brighter than their contribution to white. But it is a problem for anything that emits light, like a neon sign. A blue painted object is necessarily going to be dimmer than white surroundings. Blue is the worst in this regard perceptually, it’s only like 6% of the total brightness contribution of white. The problem is that any colors are necessarily going to be dimmer than the room, because white is the combination of RGB, and so if you just have one component, then you’re losing the brightness of the others. Have a scene in a white room, and it looks pretty normal–neither blinding nor too dim. Most sets are designed to output a comfortable white level. But that’s only true of the average brightness, not the peak. You might be thinking–my display is already bright enough. You’re probably thinking that’s the same thing, so let me explain.Īn HDR display requires two things: higher bit depth (at least 10 bits per component, ideally 12), and a higher peak brightness (3x at least, ideally 10x). So, is HDR tech strictly a question of getting blacker blacks It won’t look as pristine and detailed as native 4K of course, but it will look better than the base PS4 output. Even an effective 1440p render with checkerboarding on a 4K panel will look better than 1080p output. But I think the main thing they are trying to achieve is better image quality on a 4K panel, and they definitely do that. They do use sparse/checkerboard rendering to get there, and yes for many games “4k” is exactly that: quote unquote “4K”. The rest are usually running anywhere from 1080p to 1800p, depending on the title. There are some games, especially last gen ones that run at native 4K on the Pro, and even some new ones that do too, including Rise of the Tomb Raider. Especially at the typical viewing distances for TVs where the added detail might be minimally observable. 1080/60/ultra is a way better target than 4k/30/low. They’d be much better served using the same power to render a lower res image like 1080p at a better frame rate with higher quality settings. It’s a marketing gimmick, trying to cash in on the “4k” term. Maybe there are some low intensity indy pixel art type games that actually render in 4k, but no AAA titles certainly.ĤK is a really dumb thing for consoles to chase at this point anyway. They’re just using fancy upscaling techniques to display a 4k output image, but you could do the same thing to an atari 2600 if you wanted to. Standard is still 720p, 30fps for now.Graphically intensive games on the PS4 pro aren’t really rendering in 4k. Who knows what they will actually achieve, since it's not really industry standard yet. Most developers are aiming for 1080p, 60fps with their titles. ![]() The AA is much better and jagged lines aren't front and center, at least not as obvious as they were on the PS3. Searching google for 30FPS vs 60FPS should give you an idea of what it's like. There's a noticeable difference in 30FPS and 60FPS. Battlefield for example is 900p I believe. So any games not included on that list are probably running at either a lower resolution or lower FPS. There could be more since that list was updated but that's all I've found. Injustice: Gods Among Us Ultimate Edition I think the confirmed list of titles that run at ~60FPS, 1080p are If you're just asking because you want information and are going to get a console regardless read on: That's not to say console graphics aren't amazing, because they are, but if you care about graphics that deeply you would be best suited with a PC. If you care about graphics that much, get a PC.
