HDR-10bpp-Display-Test

The HDR-10bpp-Display-Test is a simple yet effective way to verify the HDR 4K display capabilities on Linux systems, specifically testing the color depth of 10 bits per channel. This test is essential for anyone looking to ensure the highest quality display performance on their Linux environment.

Getting Started

HDR-10bpp-Display-Test: A test project for HDR 4K display on Linux.

Prerequisites

Before running the test, ensure your system has the following software installed:

  • X server
  • Python 3
  • GTK 3
  • ImageJ (for 10-bit color depth image display)
  • ImageIO (for reading image files)

On Ubuntu or Debian-based systems, install these packages using the command:

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

Installing

ImageIO is a necessary component and can be installed via pip:

pip3 install imageio

Running the Test

To conduct the test, follow these steps:

  1. Clone the repository:

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

  2. Navigate to the project directory:

    cd HDR-10bpp-Display-Test

  3. Stop the display manager and X server:

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

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

    startx -- -depth 30

  5. Verify the X server’s color depth:

    xwininfo -root | grep Depth

  6. Launch the viewer application:

    python3 Viewer.py
python3 Viewer3.py # for video support

  7. To display an image, use:

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

    Check if the image is displayed correctly with accurate colors.

Troubleshooting

If the X server fails to start with a color depth of 30, attempt to start it with a depth of 24 instead:

startx -- -depth 24
