Is the problem using 3 webcams, or is the problem with the 4th device specifically? If you only use
D = videoinput('winvideo', 4);
preview(D)
then is it able to preview it?

Hello Trung,
I also met the problem and fixed it by making the cameras use different ports rather than sharing the same port.
