we want to buy 2K or 4k monitors, but in the "Raspberry firmware config.txt" you can only set a maximum resolution of 1920x1200.
We currently need a resolution of 2560x1440 on only one display, the second display HDMI port is not used.
Later then a resolution of 3840 x 2160
We use Raspberry Pi 4 versions
2-4K resolution possible?

Code: Select all
The following lines in /boot/config.txt worked to get a single 2560 x 1440 display working at 50hz:
# uncomment to force a specific HDMI mode (this will force VGA)

hdmi_mode=88
