Display Performance
1920 x 1080 on 14 inches produces approximately 157 PPI. The 300 nits brightness is the standard baseline for comfortable indoor visibility. 1000:1 contrast is the IPS standard. 178° viewing angles maintain color consistency at off-center positions. The 2ms response time provides clean motion during scrolling and video at 60Hz. Independent brightness and contrast controls allow matching the extender to the laptop display. Stereo speakers handle calls and casual media. Eye care technology reduces strain during extended use.
The Amazon specs list LCD for both display type and technology. The product bullets describe the panel as “IPS.” Color gamut is not specified. The glossy finish enhances vibrancy but reflects light. For a 14-inch extender from the same manufacturer family with 360° rotation, see the KEFEYA 14″ 360° Rotation review.
Mac Pro/Max Compatibility
The product bullets explicitly list M1, M2, M1 Pro/Max, and M2 Pro/Max as compatible. Pro and Max chip variants natively support more external displays than base M-series chips. This makes the S1 a broader Mac option than extenders that only list base M1/M2/M3. Android, Chrome, Linux, PS4, and Switch are also listed.
Connectivity
| Connection | Cables Needed |
|---|---|
| USB-C (full-function) | 1x USB-C (video + audio + power) |
| HDMI + USB-A | 1x HDMI (video + audio) + 1x USB-A to USB-C (power) |
Plug & Play. All three cables are included. For USB-C video requirements, see our USB-C portable monitor guide.
Same Manufacturer as Teamgee and KEFEYA
The Amazon data shows the manufacturer as Shenzhen Baijiayoupu Technology Co., Ltd. This is the same company behind Teamgee and KEFEYA branded products. This may indicate shared components, similar build quality, or related product lines across these brands. For another product from this manufacturer, see the Cenerius 14.2″ Extender review.
Potential Drawbacks to Consider
| Consideration | Detail |
|---|---|
| Panel Type Unclear | LCD in Amazon specs, IPS in bullets. |
| Color Gamut Not Specified | Cannot assess color range. |
| Glossy Finish | Reflects ambient light. |
| 1000:1 Contrast | Standard baseline. |
| 60Hz | Productivity-focused. |
| Single Panel | One screen. Creates dual-screen with laptop. |
Who This Monitor Is Best For
Mac M1/M2 Pro and Max users who want a portable extender: The explicit listing of M1 Pro/Max and M2 Pro/Max alongside base chips provides broader Mac coverage. 300 nits, 2ms, stereo speakers, and 180° rotation in a 2.33 lb package with storage bag delivers a practical travel setup.
Users who want budget specs with brand-family backing: Same manufacturer as Teamgee and KEFEYA. 1-year warranty and after-sales support.
Who Should Look Elsewhere
Users who need verified IPS and color gamut: Panel type conflicts between specs and bullets. Color gamut is missing.
Users who need matte finish: The screen is glossy.
Pros and Cons
| Pros | Cons |
|---|---|

| Adjustable kickstand, 180° rotation | 1000:1 contrast, standard |
| 2.33 lbs, storage bag included | 60Hz, productivity only |
| 3 cables included (USB-C, HDMI, USB-A) | Single panel |
| Wide compatibility (Windows/Mac/Android/Chrome/Linux/consoles) | |
| 1-year warranty |
Final Verdict
Cenerius’s S1 provides a 14-inch 1080P extender with 300 nits, 2ms, stereo speakers, eye care, adjustable kickstand with 180° rotation, and broad Mac Pro/Max compatibility at 2.33 lbs. Three cables and a storage bag are included. The same manufacturer (Shenzhen Baijiayoupu) produces Teamgee and KEFEYA products.
Color gamut is not specified. The panel type shows LCD in Amazon specs and IPS in bullets. The glossy finish reflects light. For users who want a lightweight, budget 14-inch portable with Mac Pro/Max support, stereo audio, and all cables included, the S1 covers those basics. For users who need verified IPS, color gamut data, or matte finish, alternatives with more complete listings are available across our comparison pages.
