Stands like these work well for tools, jewelry, and antique pottery.
If the case does work well for a display (if it has an open top or a clear front panel), you can absolutely keep the objects inside.
If the object is too fragile to display, consider framing it instead.
Museum glass will help cut down on UV rays coming in that might fade or warp the artwork.
Get creative with how you display your monitors. If a traditional TV style isn’t the look you’re going for, pick out some vertical display monitors that span from floor to ceiling instead.
Try to keep the labels conversational. The guests should enjoy reading through them as they walk throughout the displays.
You can also set up dimmer lights to control the intensity of each bulb.
