Media Player Problems with Large Resolutions

We need to play a large video (2560x1080 in our case) fullscreen over the game window and media player assets seem to have trouble playing anything around or over 1080p. Are there any solutions to that problem besides lowering the resolution of the video? Is it possible to change this limit through code?

If a media player asset can’t work does anyone have other suggestions for how we might able to achieve playing a large video fullscreen over the game window?

This question has been asked before (like here: https://answers.unrealengine.com/questions/190722/media-framework-360-video.html) but I couldn’t find any recent responses.

Any help would be great appreciated!
