Display 2k bug

Hi,

I am new on this forum and this is my first topic

I just bought a new LCD screen for my SLA printer which is using NanoDLP with a raspberry pi 3.
My screen is a JDI manufacturer model: TFTMD089030. It's a 2K display (2560x1600), but I have a bug. The screen is not configured correctly despite my settings in the NanoDLP setup. The display shows the image in triplicate (see photo attached).

Do you have any idea how to fix the problem?

Thank you in advance for your help!

Jb

What happens when you display dynamic patterns on projector calibration page?

Hi Jb,

I got similar 2K screen. You need to configure "config.txt" file in the Pi root folder. What i did was backup the config.txt file and create a new configuration with below settings. It works for me.

overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0
#disable_overscan=1
hdmi_drive=1
hdmi_ignore_edid=0xa5000080
hdmi_group=2
hdmi_mode=87
#60Hz
hdmi_pixel_freq_limit=400000000
hdmi_timings=2560 0 123 10 50 1600 0 12 4 4 0 0 0 60 0 222000000 0
max_framebuffer_width=2560
max_framebuffer_height=1600
display_rotate=0
framebuffer_width=2560
framebuffer_height=1600
