Graphics, sound and multimedia • Pi4 KMS HDMI resolution

HDMI-0 output of Pi4 in KMS mode shall drive a display with 1500 x 256 pixel resolution.

The EDID shows this data and is working with correct resolution on a PC:
1500x256p hfp:40 hs:144 hbp:54 vfp:3 vs:10 vbp:3 pixel clock:28 MHz

Settings in /boot/config:
hdmi_group:0=2
hdmi_mode:0=87
hdmi_cvt:0=1500 256 60

X and DRM show wrong resolution of 1496x256

What can be done to get the full resolution?
Is there a limitatuion?
