Can not see content clearly on the iPhone 4 from VNC viewer

I just jailbroken an iPhone4 (iOS4.2.6, CDMA) for running the script.
But it doesn’t show the screen clearly. See attachment.
Do I need to do anything special for iPhone 4?
If I can’t see it on the eggPlant viewer, is there anyway to catch objects?
I tried on iPhone 3GS before, it displays correctly.

It’s fixed now. It’s Veency VCN server problem. Not the eggPlant viewer problem.

Glad you were able to resolve it. Thanks for following up.
