My tv is 1080p but shows 720p1/6/2023 ![]() Remember, physical resolution is defined by the number of pixels on a display. But why would you need to increase an image’s resolution? Wikipedia These algorithms effectively add pixels to an image to increase their resolution. Upscaling Makes an Image “Bigger”Įvery TV contains a mess of interpolation algorithms, which are used to upscale low-resolution images. Now that we’re all brushed up on the difference between physical and optical resolution, it’s time to get into upscaling. We’re mentioning this to reinforce the idea that screen size isn’t the same thing as physical resolution, and that a screen’s pixel density doesn’t define its physical resolution. A 4K iPhone, for example, has a higher pixel density than a 70-inch 4K TV. Pixel Density: The number of pixels per inch on a display. All 4K displays contain the same amount of pixels, but on smaller 4K displays, the pixels are closer to each other, so they have a high pixel density.Sometimes, this is a result of upscaling, but we’ll get back to that in a minute. This leads to blurry images and contrast. TVs sometimes squander their high physical resolution by displaying video with a crappy optical resolution. When a photo looks sharp and has a clear dynamic range, it has a high optical resolution. Optical Resolution: This is why your old disposable camera photos look better than your pretentious friend’s fancy digital camera photos.Physical resolution is at the mercy of optical resolution. While TVs with a high physical resolution can use their extra pixels to offer additional detail, it doesn’t always work out that way. All 4K displays, regardless of their size, contain the same number of pixels. A 4K TV has more pixels than a 1080p TV, and a 4K image is four times the size of a 1080p image. Physical Resolution: On a TV spec sheet, the physical resolution is simply referred to as “resolution.” It’s the number of pixels on a display.We’re also going to cover pixel density-but don’t worry-we’ll keep things short and sweet. These aspects work together to create a good image, and they’re the basis for understanding upscaling. Maybe you know this already but you can’t choose a resolution directly (unless you mean the video_mode), but you can do it indirectly: the vertical resolution can be set either by turning integer scaling on (giving you the largest integer multiple that will fit) or by using vscale_border to set how much blank space there is above and below (so by subtracting the blank space from the resolution set in video_mode you get the resolution of the display area).However, we tend to forget some key aspects, namely, the difference between physical resolution and optical resolution. I was able to put in settings for all cps2 games with, but didn’t do anything to New Rally X. Alternatively you can use the rbf file name sometimes - I’m not sure exactly when. In the cores which do have it, I think you have to have vscale_mode=0 and the resolution set to 1920x1080 for it to show up as an option.įor custom resolutions, if you open the OSD while running the game, the name you need for the ini will be written vertically at the left of the display (nrallyx for New Rally X). I think most of the consoles have it, not sure how many if any of the arcades do. I think you’ve seen this in another thread, but the 5x crop has to be added to each core’s implementation. If i want to set a custom resolution for a specifc core (like New Rally X) where do i find the name i must use in the ini? I managed to get almost every game to look right, i have two more questions:Ĭan i set Arcade cores, like CPS2 to 1920 x 1080 and 5x vertical crop like console cores? HV integer will also do horizontal integer scaling. Setting it to V-integer will scale to the largest vertical integer that will fit. Alternatively in the OSD under “audio & video” (location might depend on core) there’s an option for scale. For 4x, you can set vscale_mode=1 in mister.ini, which will result in integer vertical scaling which will usually be 4x for console cores because it goes to the largest multiple that doesn’t exceed the screen size, which is often 224x4=896. Depending on the internal resolution of the core, 5x may be larger than 1080 and you’ll lose a few lines of picture, but you’ll have the whole screen filled vertically with integer scaling. Anyways, at 1920x1080 with vscale_mode=0 in mister.ini then you should get a menu option for 5x scaling in the OSD of most console cores. That said, at that kind of resolution the unevenness might not be obvious. ![]() If you use 1200p then the TV will have to upscale it unevenly. For a 4K I’d stick with 1920x1080, because then it’s a clean double to match the TV’s resolution.
