Screen, not computer
The “Technology” section also holds computers, laptops and phones. This category is about the display alone, so it is the right place for a hardware listing, a workspace illustration or an icon meaning “desktop version”.
Blank or filled screen
For mock-ups pick a monitor with a black or neutral screen seen straight on: a screenshot then fits without distortion. Angled views look livelier but need perspective correction. Monitors with a vendor logo on the bezel are best kept for reviews, while generic ones work anywhere.
