{{#seo: |title=Vita Homebrew Apps (System Tools) - GameBrew |title_mode=append |image=vitabrightluteditor2.png |image_alt=Vitabright Lut Editor }} A companion app for Vitabright plugin that allows to easily tweak OLED gamma tables. Requires [[Vitabright]] 1.1 or later. ==User guide== Keep in mind that the changes won't be permanent until you press Start in the app in order to write them to ur0:/tai/vitabright_lut.txt. Note that 1 line = 1 brightness level. In a line there are 21 numbers (2-digits each). It's actually 7 groups of 3 colors. It goes like this: [RR GG BB] [ RR GG BB] [RR GG BB] ... Each group corresponds to an intensity. The first group is for intensity levels from 171 to 255, second one is for 81 to 171, etc. The last group is a bit different, but you shouldn't need to change it. So by changing these values, you can tweak how the OLED displays high/low intensity colors. Easiest to understand is experimenting. Put some values to 0 and see what happens. You can learn more about about how the lut table works [https://github.com/devnoname120/vitabright/wiki/What-is-the-format-of-the-OLED-gamma-table%3F here]. ==Controls== Triangle/Square - Change the brightness level you're editing. Select - Change the screen brightness level to the one you're editing. Cross - Cycle through the test images. Start - Write your changes to ur0:/tai/vitabright_lut.txt (warning: this will overwrite the file) Circle - Cancel your changes and reload ur0:/tai/vitabright_lut.txt (this won't work if you've already pressed Start) Arrow - Move around and increase/decrease values This is a system app so you can always leave it with the HOME button and open for example a game. You can then come back to this app. ==Screenshots== https://dlhb.gamebrew.org/vitahomebrews/vitabrightluteditor3.png https://dlhb.gamebrew.org/vitahomebrews/vitabrightluteditor4.png https://dlhb.gamebrew.org/vitahomebrews/vitabrightluteditor5.png ==Media== Video: https://streamable.com/ltnlpc ==External links== * Twitter - https://twitter.com/devnoname120/status/1340722861590384642 * GitHub - https://github.com/devnoname120/vitabright-lut-editor * VitaDB - https://vitadb.rinnegatamante.it/#/info/601
