The advertising effect of outdoor video commercial is constructed not on the smoothing of the outlines of letters, but on drawing of attention to the dynamic advertising clip. Therefore selecting one LED screen or another – it is much more important to look at the real sizes, real resolution, and real brightness at the real site of LED screen installation.
Certainly if you choose LED screen with the very dense pixel pitch (3 mm, 6 mm, 8 mm, 10 mm) and with sizes up to 3 m in height and 4 meters in width and you are going to look at it from the close distance. This is just the case when virtual pixel comes handy.
But in case of outdoor advertisement with LED screen sizes more than 3x4 meters all the advantages of virtual pixel are neutralized by distance. Then why do you need such option (especially for additional price), which neither you nor your clients can see from some distance? Are you ready to pay real money for a virtual screen? Think twice.
