Downloaded and Upgraded my 2910 over the w/e, WOW - DVI is now absolutely stunning
Some of the things I've found are better black levels, much brighter, more detail, better colour saturation. Component - reduced overscan and much better colour saturation
Create a directory for the files
Right Click over the link, use the "Save Target as..." option and save into the directory you created above
Unzip the .zip file and put all the files into the same directory, there are 2 - 2910firmware.pdf & d21zsavd.cfw
Follow the instructions in the .pdf for burning to CD (CD-R & CD-RW can be used)
Upgrade (you don't need to connect any display device, all messages are shown on the units display)
You don't have to Initialize the unit back to Factory Default settings either
Enjoy
