Best triple laptop screen extender, and which laptops can run both side screens
Updated 2026-11-10 · Pick: Trio 3 Pro: $433.49 on mobilepixels.us (checked 2026-11-02): https://dealectric.com/go/mobile-pixels-trio-3-pro
Short answer. The best triple laptop screen extender is the Mobile Pixels Trio 3 Pro, with two 14.1-inch 2240×1400 screens. Check compatibility: a base M1, M2 or M3 MacBook drives only one external display with the lid open, so plan on Mobile Pixels' free software for the second screen.

What the differences mean
A 16:10 panel covers diagonal² × 0.449 square inches and a 16:9 panel covers diagonal² × 0.427. Dividing that area by the weight and by today's maker price gives the figures below.
- Trio 3 Pro: 2 × 14.1² × 0.449 = 178.7 sq in. 178.7 ÷ 4.13 lb = 43.3 sq in per lb. $433.49 ÷ 178.7 = $2.43 per sq in. Sharpness: √(2240² + 1400²) ÷ 14.1 = 187 ppi.
- UPERFECT BE14BF: 2 × 14² × 0.449 = 176.2 sq in. 176.2 ÷ 3.39 lb = 52.0 sq in per lb. $389.99 ÷ 176.2 = $2.21 per sq in. Sharpness: 2641.5 ÷ 14 = 189 ppi.
- Xebec Tri-Screen 3: 2 × 13.3² × 0.427 = 151.2 sq in. 151.2 ÷ 3.7 lb = 40.9 sq in per lb. On a Mac, ($699 + $59 adapter) ÷ 151.2 = $5.01 per sq in. Sharpness: √(1920² + 1080²) ÷ 13.3 = 166 ppi.
- FOPO S788: 3 × 16² × 0.449 = 345.2 sq in. 345.2 ÷ 5.82 lb = 59.3 sq in per lb. $699.99 ÷ 345.2 = $2.03 per sq in. Sharpness: √(1920² + 1200²) ÷ 16 = 142 ppi.
- Cevaton Z2: 2 × 15.6² × 0.427 = 208.0 sq in. 208.0 ÷ 5.51 lb = 37.7 sq in per lb. $399.99 ÷ 208.0 = $1.92 per sq in. Sharpness: 2202.9 ÷ 15.6 = 141 ppi.
The Trio 3 Pro and the UPERFECT add almost the same area at almost the same sharpness. The UPERFECT is 0.74 lb lighter and $43.50 cheaper. The Trio wins because its connection is documented for each laptop type: two cables with no software on most laptops, and a known software route on base Macs. $433.49: https://dealectric.com/go/mobile-pixels-trio-3-pro

Which MacBooks can run both side screens
A triple extender only works with the laptop open, because the laptop's own screen is the middle one. Apple's lid-closed trick for adding a second display therefore doesn't help. Apple says the M3 MacBook Air runs one external display with the lid open and a second only with the lid closed. It says the M4 MacBook Air runs up to two external displays.
| MacBook | External displays (Apple or Macworld) | Trio 3 Pro setup |
|---|---|---|
| MacBook Air M1 or M2 | One (Macworld) | Mobile Pixels' free software for the second screen |
| MacBook Air M3 | One with the lid open; a second only with the lid closed (Apple) | Same one-display limit as M1/M2, so plan on the same software |
| MacBook Neo | One; closing the lid does not add a second (Apple) | Mobile Pixels' free software (Macworld) |
| MacBook Air M4 | Up to two (Apple) | Two USB-C cables, no software |
| M1–M3 Pro/Max, any M4/M5 | Macworld says these run both screens without software | Two USB-C cables, no software |
Why one cable is harder on a Mac. Xebec says Apple does not support MST, the DisplayPort feature that lets one cable drive two screens. That is why Xebec requires its Tri-Screen 3 Mac Adapter, which has DisplayLink chips and needs the DisplayLink driver, for all Mac users, even on an M4. That brings a Mac-ready Tri-Screen 3 to $758, $324.51 more than the Trio 3 Pro. The Trio avoids the MST problem by running one USB-C cable per screen. Simon Jary at Macworld quotes its manual: no driver is needed if the laptop has two DisplayPort-enabled USB-C ports.
Power. Jary found the Trio's screens cannot reach their 300-nit maximum on laptop power alone. A power adapter plugged into the Trio gives full brightness, and that same adapter supplies the up-to-65 W pass-through to the laptop. CHIP.pl's spec table lists 11 W draw in use. The FOPO S788 also needs an external power supply. FOPO's driver-based setup is the documented route for running three added screens on a base M1, M2 or M3 Mac. $699.99 on fopomonitor.com, $630 through this link: https://dealectric.com/go/fopo-s788-16-inch-triple-laptop-screen-extender
Not recommended
Cevaton T2 Pro ($199.99 at Cevaton, 2026-11-10). Its listing title says “Triple Laptop Screen Extender”, but Cevaton's own description says it adds “an extra 14” Full HD display, creating a mobile dual-screen workstation.” Confirm the screen count with the seller before buying it as a triple extender.
