HDR-10bpp-Display-Test

This is a simple test to verify the HDR 4K display on Linux using a color depth of 10 bits per channel. The test requires an HDR 4K display and a Linux environment with the X server installed.

Getting Started

Prerequisites

To run the test, you will need the following software installed on your system:

• X server
• Python 3
• GTK 3
• ImageJ (for displaying images with a 10-bit color depth)
• ImageIO (for reading image files)

You can install these packages on Ubuntu or Debian-based systems by running the following command:

sudo apt-get install xserver-xorg python3 python3-gi python3-gi-cairo gir1.2-gtk-3.0 imagej

Installing

To install ImageIO, you can use pip:

pip3 install imageio

Running the test

To run the test, follow these steps:

1. Clone the repository:

git clone https://github.com/yourusername/HDR-10bpp-Display-Test.git

1. Navigate to the project directory:

cd HDR-10bpp-Display-Test

1. Stop the display manager and X server:

sudo systemctl stop lightdm || sudo systemctl stop gdm
sudo pkill Xorg

1. Start the X server with a color depth of 30:

startx -- -depth 30

1. If the X server was started successfully, the output of the following command should indicate a depth of 30:

xwininfo -root | grep Depth

1. Launch the viewer application:

python3 Viewer.py
python3 Viewer3.py # video support

1. The viewer window will open. To display an image, run the following command:

imagej --no-splash /path/to/image

1. The image should be displayed in the viewer window. Verify that the image is displayed correctly and that the colors are accurate.

Troubleshooting

If the X server does not start with a color depth of 30, try starting it with a color depth of 24:

startx -- -depth 24
