🏎️ Why Triple Screens?

Triple monitors give you a wider, more natural cockpit view of the track. You’ll see cars beside you without panning, spot corner entries and apexes earlier, and have better door‑to‑door awareness.

  • See cars alongside without camera movement
  • Read corners sooner for quicker reactions
  • Smoother wheel‑to‑wheel racing awareness
💡 Single screens are still great—especially when you’re starting out or limited by space/budget. But if you’re ready to level up immersion and reaction time, triples can make the sim feel truly alive.
📏 Pro Tip: For most rigs, 32‑inch monitors hit the sweet spot between cost, field of view, and immersion. Big enough to feel real, small enough to keep total cost and footprint reasonable.

Step 1

Dial in your seating

  • Wheel center at chest/shoulder height, slight upward tilt
  • Arms: ~90° bend; wrists rest on wheel rim
  • Legs slightly bent at full brake—don’t lock knees
Pro tip: set seat first; everything else references your eye position.
Step 2

Place the monitors

Center: aligned to face; bottom edge just above wheelbase; eye distance 23–28". Write it down.

Sides: rotate toward your face. Measure diagonal from center to side corner. Write it down.

Step 3

Align in Windows

  • Right‑click desktop → Display Settings
  • Drag screens so their tops align perfectly
  • Set center as Main Display
Even a 1‑pixel misalignment can distort iRacing.
Step 4

Edit iRacing config

Documents → iRacing open rendererDX11.ini and rendererDX11Monitor.ini, then match values:

DX11 Config border=0 fullscreen=0 windowedMaximized=0 windowWidth=7680 ; 3 × 2560 windowHeight=1440 ; your monitor height windowedPositionX=-2560 windowAlignment=1 deviceIdx=0
Adjust windowWidth, windowHeight, and windowedPositionX for your monitor resolution.
Step 5

Calculate side angles

Use any triangle calculator:

  • Side A = monitor width (e.g., 28")
  • Side B = monitor width
  • Side C = measured diagonal (e.g., 49.7")

180 − top angle = monitor angle (e.g., 55°). Save this for iRacing.

Step 6

Set up in iRacing

Fix side‑screen warping

In a test session → Replay → Ctrl + F12 (Camera Tool):

  • Vanish Y: adjust until side lines look straight (halve the original value if needed).
  • Orient P: set to Vanish Y × 0.3.
Example: Vanish Y = −13 ⇒ Orient P = −3.9
Step 7

Fine‑tune your view

  • [/] = FOV
  • Shift + [ or ] = horizon
  • Ctrl + [ or ] = seat height
Goal: road at eye level, natural dash/wheel proportion—no “periscope” view.
