mipi csi2 tx, upper limit of video width

Hi, I am using Quartus ver 26.1 PRO Edition and investigating the MIPI CSI-2 TX IP on Agilex 5 E.  I generated the CSI-2 Example Design and am running a RTL simulation. To change the video width, I modified the setting of FRAME_WIDTH_PIXELS in cfg_pkg.sv. When FRAME_WIDTH_PIXELS = 3840, the operation is normal.

The IP setting is follow:
