OSEE brought a 15-inch version of its Mega 22S4 multi-view monitor to IBC 2026. The Mega 15S4 keeps the same core feature set (multi-input display, 1,500 nits, the full onboard tool suite) in a smaller footprint, and adds a new swivel-arm mounting system OSEE says could eventually make its way to the larger monitor too. We spoke with OSEE’s Richard on the show floor.
What it is
According to OSEE, the Mega 15S4 carries over the Mega 22S4’s spec sheet into a 15-inch panel with no cuts. That means the same 1,500 nits brightness, the same multi-input handling (OSEE says you can run two, three, or four sources on screen at once via SDI or HDMI), and the same 178-degree viewing angle. The panel itself is a step up from the 22S4’s, described as an “IPS black” panel with deeper, richer blacks and a slightly glossier coating, without giving up any of that viewing angle.

The new mount
The Mega 22S4 uses a VESA mount that has to be unclipped and slid back in to switch between vertical and horizontal, which Richard called a bit cumbersome on set.
The Mega 15S4 replaces that with a swivel arm, so switching orientation is just a matter of turning the monitor and dropping it back in, no removal step. Richard said the resistance on the arm is strong enough that it won’t sag even with a monitor and battery mounted. He wouldn’t confirm it, but said a version of this mount for the larger 22S4 is likely in development, pending R&D to make sure it can support that monitor’s weight with a V-mount battery attached.
Client feed and accessories
The rear cheese plate lets a wireless video transmitter (Richard referenced something like a Hollyland-style unit) plug in off the HDMI output, so a director or producer in one room can send the program feed to clients or talent in another. The included case is the same one used with OSEE’s prior 15-inch monitors: it has rear-zipper access to ports, V-mount, and controls while the monitor stays in the bag, and the front cover doubles as a sun hood. Both a V-mount and gold mount battery plate exist for this monitor, with V-mount standard and gold mount available as a swap, and a second cheese plate position is available if you want to add one.
Price & availability
Richard quoted approximately EUR1,300 for the Mega 15S4, available starting next month, though he noted the price could still move slightly before launch. For comparison, the Mega 22S4 launched at EUR1,599 in Q4 2025.
