Whether it is Shen Hao or something else beats me. However, I get nowhere with the standard screen fitted on my SH HZX57. The image is dim at best, focussing a chore. I shoot various 4X5 systems and never had the urge to replace a screen so far. Whether it be the standard Wista screen, the screen used by Walker or the Sinar fresnel, all work great. As such, I never looked into alternatives. I am not looking to spend a fortune on the screen as I am quite sure I will sell the SH. It is just to heavy and cumbersome to work with. However, I want to give it an honest try. Heck who knows, I may even change my mind if I can see something on the screen...

Maxwell? Boss? Asian knock-off?
