external monitors with different resolution 2K 4K, diff. errors, daisy chain, Ubuntu
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
Setup:
ThinkPad L450 [Ubuntu 16.04.5 LTS, kernel 4.13]: 1920 x 1080, Intel HD Graphics 5500 & UltraDock – 90W EU (DisplayPort 1.2)
ThinkPad L480 [Linux]: 1.920 x 1.080 (IPS), Intel UHD Graphics 620 & Lenovo ThinkPad Ultra Docking Station - 135 Watt (DisplayPort 1.4)
Benq PD2700U - 16:9, 3840 x 2160 4K UHD (2160p)
Dell U2518D - 16:9, QHD 2560 x 1440 at 60 Hz
- both monitors can daisy chain
I can set up the monitors with daisy chain OR via the 2 DisplayPorts outputs of the Docking with a resolution of up to 2560 x 1440 (and 1920 x 1080 for the Laptop screen) for the L450 and L480 (with the docking stations).
BUT when I change the resolution of the Benq 4K monitor to 3840 x 2160 (59.xx Hz) it results in
- ubuntu: dell 2k monitor gets black (but is shown to be still connected in
xrandr --verbose | grep " connected")
Errors are:
could not set the configuration for CRTC 65
required virtual size does not fit available size: requested=(8320, 2160), minimum=(320, 200), maximum=(8192, 8192)
requested position/size for CRTC 65 is outside the allowed limit: position=(4480, 0), size=(3840, 2160), maximum=(8192, 8192)
The result of
xrandr --output DP-2-1-8 --mode 3840x2160 --rate 29.97 --primary --output DP-2-1-1 --mode 2560x1440 --rate 59.97 --right-of DP-2-1-8 --output eDP-1 --mode 1680x1050 --rate 59.95 --left-of DP-2-1-8
It happens via the 2 DP ports and via daisy chain (Benq 4K to Dell 2K).

Ubuntu kernel 4.13 is EOL & unsupported (has had no updates in a long time), so I'd suggest you upgrade your system. Ubuntu 16.04.5 should be using kernel 4.4 or 4.15. I don't know NIX OS, but are you running Ubuntu?
