Hi,
The only thing I would recommend is to try and minimise all system resources on the PC you are displaying on the monitors (i.e. turn off transparancy effects / anti virus scans).
I have a HP PC that is low spec (AMD Athlon) that has about 7 reports on Chrome (with auto refresh add-in) and the AutoTab program (I mistyped the name of the program, it's actually AnalogX AutoTab - http://www.analogx.com/contents/download/System/autotab/Freeware.htm)
It uses very little memory (about 1mb).
If your reports are using up memory on your PC, try and set the Chrome add-in auto refresh rate to something quicker (i.e. every 5-10 minutes).
Mine runs for months with no problem (until I have a powercut!).
Thanks!
