AUO display Driver G065VN01 01 -TTL-

Hello All, I have a problem configuring WindowsCE registry for this display. I have 10 of them.
I'm using this configuration shown below, but the image is sometimes flickering or pink or noisy.
The displays have been already cross-checked by AUO itself and reports OK. They told me also to try to shield the signals in data cable, but I made 200 data cables that are ok for other displays and always everything was good.
However, this is the configuration:

reg open \drivers\display\Samsung
reg create key mode100
reg set value name string "AUO G065VN01-V1"
reg set value msignal dword 2
reg set value rows dword 480
reg set value LPP dword 480
reg set value width dword 132
reg set value height dword 99
reg set value contrastenable dword 0
reg set value contrastvalue dword 0
reg set value type dword 6
reg set value config dword 0x00400000
reg set value columns dword 640
reg set value PPL dword 640
reg set value bpp dword 16
reg set value lcdclk dword 20
reg set value HSW dword 32
reg set value BLW dword 68
reg set value ELW dword 60
reg set value VSW dword 2
reg set value BFW dword 33
reg set value EFW dword 10
reg set value EnableCursor dword 1
display mode set 100
reg save
reboot hardware

This is a 6,5" 640x480 TFT LCD monitor
Is there something wrong for you? Can I try other values?
Thank you,
best regards.

Yes, with lcdclk=25 is much better, almost ok
but still when moving mouse or loading apps, I see some pixel blinking, like a sort of noise. and the white is not white.

kind regards
Giulio

and yes, mode=3 gives same results
