Vivitek DH4661Z

We purchased a Vivitek DH4661Z in January 2019 and have been ulnable to obtain satisfactory colour, contrast and sharpness for our venue. 

This is despite having the projector professionally calibrated.
Could you advise if there is a programming fault with this model that could be fixed please.

    Hello Peter,

    Sorry for the issues you are experiencing. Unfortunately we are unable to provide support on third part end products. We only provide support for the TI ICs and EVMs (evaluation modules) and do so in order to assist development of products. I would recommend contacting Vivitek for assistance.

    Thanks,
    Kyle

    You are effectively saying it is not your role to follow up on this. Vivitek had previously been of no help. We now have a AU$5200 projector that is not fit for purpose in our U3A volunteer community group. There are over 200 U3A groups throughout Australia with membership over 200,000 participants. https://www.worldu3a.org/ We are to replace the Vivitek with a Panasonic projector which gives good quality imaging on testing much better than Vivitek. We are unlikely to recommend Vivitek to other U3A groups.
