Monitor placement: height, distance, angle
**Ideal height**: Top of monitor at eye level (or slightly above). Prevents neck strain. **Distance**: 24-30 inches from eyes. At this distance, 1440p looks sharp, 1080p shows jaggies. **Angle**: Slightly tilted down (10-15 degrees). Reduces eye strain. **Why it matters**: Wrong placement = neck/back pain in 3-4 hours.
Keyboard and mouse placement for comfort
**Height**: Elbows at 90 degrees, wrists straight (not bent). Keyboard at forearm height. **Angle**: Keyboard slightly angled away (not flat). **Mouse**: Close to keyboard, wrist supported on mousepad. Arm relaxed, not stretched. **Why**: Proper positioning prevents carpal tunnel, tendonitis.
Lighting: bias light, desk lamp, ambient
**Bias light (behind monitor)**: Reduces eye strain, improves contrast. 2000-6500K color temp. **Desk lamp**: Angled away from monitor (no glare). 60-100W equivalent brightness. **Ambient (room)**: Soft background lighting. Prevents dark room eye fatigue. **Best setup**: Bias light + desk lamp + natural window light.
Chair: lumbar support, armrests, recline
**Lumbar support**: Adjustable. Supports lower back curve. Critical for 8+ hour sessions. **Seat height**: Feet flat on floor or footrest, knees 90 degrees. **Armrests**: Adjustable, supports elbows at desk height. Prevents shoulder strain. **Recline**: Nice-to-have. Allows position changes.
Cable management and desk real estate
**Cable routing**: Behind monitor arm, under desk in raceway. Hide cables completely. **Desk space**: Gaming mouse + keyboard only on desk. Storage for headset, controller underneath. **Monitor arm**: Frees up desk space vs monitor stand (saves 4-6 inches).
