As a new user of UHD2000 having some issues with the poster wall I am not sure how to install a firmware upgrade and am reluctant to try because I would not want the upgrade to undo everything I've already accomplished. What happens when you upgrade? Does everything you've done go away and you have to start all over again?
My advice its new so take a step back as just familrise yourself with the unit and how it runs and get it set up right and learn how to get Poster wall sorted first with your movies etc ......
Firmware update if done wrong or an issue occurs could render your unit useless .
Update yes it adds more function etc but just read about it first so you feel confident .
its basically straight forward once you have done it once .
get your unit running up for a while and yes later on do an update .
Read my Z10 Thread you may learn some tips to .
