My Dell monitor is adjustable vertically, horizontally and rotatable.

I use the AmazonBasics metal monitor stand. Cheaper than most books and awesome :)

I use Grovemade to get some storage under the space.

I use my audio interface as my monitor stand

I previously used an encyclopedia. Now I use a cut of pine and 4 door stops from Lowes. Cost about $10 for the whole project and took about 10 minutes to make (not including putting danish oil on it).

Just a bunch of old Monocles.

Player's Handbook, Monster Manual, Dungeon Master's Guide

I laughed.

I use The Chicago Manual of Style, 16th Edition.

I have two monitors and I use two old quince jelly cans :D

I'm short.

Two architectural reference books. McKay Building Construction, volumes 1-2 and 3-4. The contents are outdated, but they are still proving very useful.

I use a Nordic Appeal iMac Stand.

I used to have the "University Physics" by Young & Freedman, but currently I'm using the first generation Intel Mac Mini keeping the display on eye level. I have Apple LED Cinema Display and motorized standing desk.
