@Bubbles: Alas I have had a few people now asking me regarding the same problem, they can't run the wallpaper when they're on Win7 and with a lower resolution then 3440x1440 (although I think 2560x1440 will work but that is still widescreen). Not sure if problem lies with wallpaper engine or Win7, perhaps a combo of both. Guess you could ask the WE developers regarding this and see if they respond (although this may already be covered so check the discussion forum) otherwise perhaps think about upgrading to win8 or 10, either that or treat yourself and buy a nice ultrawide screen ;).

Yes, i run wallpaper engine on windows 7 and get an error everytime i try to run a video larger than my native resolution. but thx for your fast reply. I hope wallpaper engine can enable larger videoplayback on win7 aswell in the future.

@Bubbles: Hi, you should be able to view my wallpaper videos in any resolution, although anything but 21:9 may result in either black bars top an bottom or you could try to cover or stretch the wallpaper (although that might look odd). Unless you are running Win7 which I believe has an inherit problem with wallpaper engine when you try to view videos larger then your native resolution (something about a 4k video error iirc).

Can you please make 1080p version from your ehtan carter videos?
