So in light of the FTB packs being removed from the Twitch launcher, I've moved back to the Legacy FTB launcher for Windows (downloaded from this post), but I've found that when I run FTB Ultimate Reloaded, the game runs at a much lower resolution, as seen here:

Does anyone know how I might be able to fix this? I've tried changing window size and resolution in the launcher under the "options" tab, but it doesn't seem to have helped.

Any help would be greatly appreciated.
