Small money, disproportionate quality-of-life.
Monitor arms, cable trays, privacy filters. Each one is under $50 and each one you'll notice every day.
Frees your entire desk surface and lets you finally put the monitor at eye level. It's not the fanciest arm, but it holds two 27" panels rock-steady for under $60.
The under-$60 fix for HIPAA-adjacent worries. Anyone off-axis sees black. Not perfect for color work, but for PHI or client notes it does what it promises.
The real thing, not the Amazon foam that crumbles in a year. Twelve wedges is enough for a small room's first reflection points, which is what actually matters.
