When quality needs to be high, for a whole office to view, 24/7, how should I prepare the output?

It is all Dashboard Guages. Until now it's been 4 A4 landscape pages of a dial in each corner with time, date, stats and logo in the centre. It all looks great on the Crystal Editor, but horrific resolution in the web viewer - can't even distinguish where each rough nearby guage needle is pointing! It's like ZX Spectrum graphics. The plasma screen will be terrible. To run the output with Crystal editor will be the only way...?

I'm tasked with crunching all the 12 guages into one page from those 4 to start with. Should I change A4 to a different format? Haven't really dealt with that in 6 years... How to I expand the resolution and ignore paper...?

Thanks
