Product review (4 stars): isn't it more useful to show both or switching by software its huge ...
its ok for price

but you cant read in and out at same screen  same time
you have to use back button to switch between in and out ??
at least software can change screen in let says 1 every 1 min or 30 sec.
if there is any thing to set it up to that way please let me know.
isn't it more  useful to show both or switching by software

its huge screen i sure t
