David,
For a “procedures-first” G1000 setup in X-Plane 11, you’re thinking along the right lines. Two touchscreens (one for PFD, one for MFD) is the cleanest workflow and keeps you from constantly swapping views or fighting pop-outs.
Size / resolution “sweet spot”
In practice, the sweet spot usually comes down to: “big enough to accurately hit the softkeys/knobs without hunting,” but not so huge that the cockpit ends up feeling like a billboard.
- 22–24" is a very workable range for a dual-screen G1000 layout on a desk/cockpit mockup.
- 1080p at 22–24" is generally fine for readability and touch targets in the X-Plane G1000 (especially if you’re sitting fairly close).
- If you go much smaller, the touch accuracy becomes the limiting factor (especially the bottom softkeys and the smaller UI elements).
Two monitors vs. one larger touchscreen
I’d stick with your “2 x mid-sized” plan for IFR practice.
- With two, you can keep the PFD and MFD visible all the time, which is exactly how you’ll train flows and scan.
- With one large touchscreen, you usually end up wasting space or doing awkward window sizing, and it still doesn’t “feel” like a proper split.
Touchscreen “gotchas” people run into
Before you buy two of the same model, I’d just sanity-check a few practical points that bite folks later:
- Touch input per monitor in Windows: Make sure you can correctly map touch to each screen (so touching the left screen doesn’t click something on the right). Windows can do it, but it’s something you’ll want to confirm works cleanly with your exact multi-monitor arrangement.
- Ergonomics/angle: A touchscreen you’ll be poking a lot really needs the right tilt angle. Some stands are awful for “panel use” because the display sits too upright.
- Connections: A lot of touch monitors do video over DP/HDMI but touch over USB. So two touch monitors = two USB connections for touch (plus whatever your other peripherals are). Not a deal-breaker, just plan for ports/hub.
- Glare: Some touch panels are glossy; cockpit lighting can be annoying if you have a window behind you.
How I’d set it up (workflow-wise)
- Run your main scenery view on the big monitor (as you planned).
- Put the G1000 PFD window on the left touchscreen, MFD on the right touchscreen.
- Position the touchscreens at roughly the same width/spacing as the real units so your hand movements start to become “muscle memory.”
A couple quick questions so I don’t steer you wrong
- Are you planning to use the G1000 as pop-out/undocked windows on the touchscreens, or will you be using a separate panel view?
- How far from the screens will you typically sit (roughly 18", 24", 30"+)?
- Are you staying in Windows for this build (sounds like it), or is macOS a real possibility for the sim machine later?
If you answer those, I can be more specific about whether 24" 1080p is ideal for your seating distance, and how picky you’ll want to be about touch accuracy/stand geometry.
