Hi, you will find loads of posts relating to your model and the previous VW10HT on this forum, just input the model number into the search engine.
Theres a lot of people who swear by adding bits and bobs to this pj like filters etc, I myself put it on a glass shelf which is suspended between two back to back dining room chairs behind my sofa switched it on and hey presto. Only minor tweaks too contrast, brightness etc too suit my personal tastes and to be honest cannot find fault with it. I watched AOTC the other night and the picture is fantastic I am aiming to suspend it properly but its finding time and as I said picture is so good im not really in a rush to re-position it.
Theres quite a few knowledgeable people posting on these forums about these pj's so im sure you will find lots of advise after you have used the search engine.
Regards Matt...........
