I’m working on a project of making an 3d printer with my old raspberry pi 2 model B . I purchased following 2k screen from aliexpress:

I tested it with my laptop and it works perfectly. However when I connect it to the Pi, there was nothing display on screen. When I tried to add “hdmi_safe=1” to the /boot/config.txt but the result still the same. This is the output of “tvservice -s”:
state 0xa [HDMI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive
I also tried to uncomment some option in config.txt file like “hdmi_force_hotplug”, change “hdmi_mode” and “hdmi_group” but nothing changed. Only when I add “ hdmi_ignore_edid=0xa5000080”, the output of “tvservice -s” change to 1920 * 1080 but still no thing display on screen.
Can anyone help me with this problem?
Thank you very much.
