Look what i found!
Theoretically, this guide can help with wayland, because it have section about editing EDID firmware. I will check this later.
I create 2560 1440 mode with 75 hz refresh rate and it works great.
./cvt12 2560 1440 75 -b
# 2560x1440 @ 75.000 Hz Reduced Blank (CVT) field rate 75.000 Hz; hsync: 111.900 kHz; pclk: 295.42 MHz
Modeline "2560x1440_75.00_rb2" 295.42 2560 2568 2600 2640 1440 1478 1486 1492 +hsync -vsync
Kvas, i also create modeline for your screen with higher refresh rate. 34.85 hz.
./cvt12 3840 2160 34.85 -b
# 3840x2160 @ 34.850 Hz Reduced Blank (CVT) field rate 34.850 Hz; hsync: 76.530 kHz; pclk: 300.00 MHz
Modeline "3840x2160_34.85_rb2" 300.00 3840 3848 3880 3920 2160 2182 2190 2196 +hsync -vsync
