A while ago I rendered out all of the piece for the Demo Set in Lightwave so I could add things and have more control over the set.
I've added a big monitor behind the desk, a monitor over to the side, a place on the front of the desk for a logo if you want, you can change the
background image.
Open it up in Photoshop and make changes. This was made for a T40, but if you want to use all of the keyable layers, just rename the large back monitor to Input C
then bring it into VSE.
It very customizable. Everything was rendered out at 3840 x 2160. Click the link to download.
