-# corsair_lcd_tool
-A simple Python script that can be used as an alternative to Corsair iCUE for displaying images or GIFs on Corsair AIOs with LCD screens.
+# Features
+- Display any image or GIF without size or length limits on the LCD screen of a compatible Corsair AIO.
+- LED ring control with automatically calculated colors based on the currently loaded image.
+- Saving and loading of the last image position, size, etc.
+- Autostart which works fine on Windows, haven't tested it much on Linux.
+- Low resources usage compared to iCUE.
+
+# Usage
+- Install [Python](https://www.python.org/downloads/ "Python") 3.6 or newer.
+- Install [OpenRGB](https://gitlab.com/CalcProgrammer1/OpenRGB "OpenRGB").
+- Clone the repo or download as ZIP and extract it to a new folder.
+- Install the required modules using `pip install -r requirements.txt`.
+- Run the script.
+
+# Tested devices
+- Corsair iCUE H170i ELITE LCD (non-XT), 0x1b1c / 0x0c39
+
+# FAQ
+- I don't want to control the LEDs with the script / use OpenRGB, how to disable the warning popup?
+	- Delete `led_controller_openrgb.py`, the rest of the script will work fine without it.
+
+# Why?
+- Mostly because I was bored, and I don't want to keep iCUE installed just to be able to change the displayed image on the LCD. The script is 99% made by ChatGPT, so bugs / other issues can happen anytime as this is my first Python project which I started without any prior knowledge. Use at your own risk, I take no responsibility for any damage caused to your AIO, which is highly unlikely.

+# Thanks to
+- [browserdotsys](https://github.com/browserdotsys "browserdotsys") for [the gist](https://gist.github.com/browserdotsys/ef1b22c60c31d9c61e18cca30b3ce903 "the gist") that's used as a base of this script to communicate with the AIO.
