Warping mesh doesn't work for second display on Quadro RTX4000

I’m trying to create a curved multiple projection display using NvAPI_GPU_SetScanoutWarping on Quadro RTX 4000.
I place two projectors by 1x2 alignment.
The problem is that the second display has black screen when NvAPI_GPU_SetScanoutWarping get called.
First projector display works fine for the warping.
That resolution is each 3840 x 2160 , 3840x2160.
Vertexs and Texture is in from (0,0) to (3840,2160) for first display,
and them is in from (3840,0) to (7680,1080) for second one.
For example,
Display 1 is:
x=0.0000, y=194.5810, u=0.0000, v=194.5810, r=0.0, q=1.0
x=134.7377, y=1739.1628, u=134.7377, v=1739.1628, r=0.0, q=1.0
x=1476.1111, y=159.8882, u=1476.1111, v=159.8882, r=0.0, q=1.0
x=3384.5146, y=2035.1995, u=3384.5146, v=2035.1995, r=0.0, q=1.0
x=3832.5120, y=0.0000, u=3832.5120, v=0.0000, r=0.0, q=1.0

Display 2 is:
x=3840.0000, y=194.5810, u=3840.0000, v=194.5810, r=0.0, q=1.0
x=3974.7377, y=1739.1628, u=3974.7377, v=1739.1628, r=0.0, q=1.0
x=5316.1111, y=159.8882, u=5316.1111, v=159.8882, r=0.0, q=1.0
x=7224.5146, y=2035.1995, u=7224.5146, v=2035.1995, r=0.0, q=1.0
x=7672.512, y=0.0000, u=7672.512, v=0.0000, r=0.0, q=1.0

Also, I tried to translate every vertics to X axis for Display 2 like this:
x=0.0000, y=194.5810, u=0.0000, v=194.5810, r=0.0, q=1.0
x=134.7377, y=1739.1628, u=134.7377, v=1739.1628, r=0.0, q=1.0
x=1476.1111, y=159.8882, u=1476.1111, v=159.8882, r=0.0, q=1.0
x=3384.5146, y=2035.1995, u=3384.5146, v=2035.1995, r=0.0, q=1.0
x=3832.5120, y=0.0000, u=3832.5120, v=0.0000, r=0.0, q=1.0
Results is same.
What’s wrong?
I don’t setup Mosaic topology for displays.
Welcome anything help.

I solved it. The root cause is vertex coordinates.
I tried to put vertex coordination into the display’s target resolution instead of union 7680x1080.
No changes for texture coordination.
Texture coordinates is still union resolution. (because of none mosaic for me)
