I have been going through dozens of discussions on this subject, in 2018 none of the existing solutions seem to work on revive adserver v4.1.4. The question is: How can we get a wide/ larger leaderboard banner (728x90 to display properly on a smaller size mobile device. Or at least have it be swapped out/ or replaced by a smaller mobile friendly banner (e.g. 480x90) on the same zone by the same campaign.
Simply put, I imagine a situation where during the creation of a new banner: I upload a standard 728x90 banner, plus a smaller480x90 banner for mobile at the same time. I imagine the larger banner being displayed if loaded on a PC/ laptop screen, and I imagine the smaller version of the very same banner ad being displayed tif page loaded on a mobile device.
In other words Like this: IF (LAPTOP SCREEN) LOAD BigBanner; ELSE IF (MOBILE SCREEN) LOAD SmallBanner;
How can i achieve this on Revive Adserver 4.1.4? I hope my question is very easy to understand.
