They use a different monitor (clearly not a 1080) for the close-up shots (at 0:24 in the clip) than they do for the others. But they still slapped the Amiga badge on it to try to maintain continuity!
And in the overhead shot at the end, the 1080's power LED is clearly off (yet the 1000's LED is on). I'm assuming they superimposed all the screen imagery in postproduction. Plus there's a big case of
MovieOS in this scene! They probably could have done it all in-camera with a DPaint anim or AmigaVision (and with proper topaz/8) for cheaper, but there probably wasn't enough communication between the on-set art department and the VFX department to prep that ahead of time.
As an editor, I can't help but nitpick.

In narrative art, the fine details that hold people in a story are critically important, because if done wrong they can pull people out of a story. I once had to turn something down because the author described PacMan as a retro game from the late 90s running on historically inaccurate hardware. The author clearly hadn't done their research, which then led me to question the integrity of everything else in the piece. It's not as significant in this scene since the errors are so minor relative to the story that only weirdos like us (or just me

) will notice them.
P.S. I also wonder if the artistic choice to use an Amiga was a "correction" for Commodore's infamous botching of the deal to use an Amiga in Star Trek IV.
