FQQ 15.6" Detachable Laptop Screen Extender, FHD 1080P IPS Dual/Triple Portable Monitor for Laptop, USB-C/HDMI Plug & Play, Multi/Extra Travel Display Computer Monitor for 12-18.5" Win/Mac/Android-S9H vs FULLCOM 17.3 inch Screen Compatible for Dell G3 3779 Precision 7730 Inspiron 5770 0Y9WG,LP173WF4(SP)(F1), LTN173HL01-201,N173HCE-E31

Price Difference: FQQ is Significantly More Expensive

FQQ 15.6" Detachable Laptop Screen Extender costs $289.99, while FULLCOM 17.3 inch Screen is priced at $125.88, making the FQQ model about 126% more expensive. This price gap reflects a fundamental difference in function and design—FQQ offers a portable, multi-display solution with advanced connectivity and build quality, whereas FULLCOM provides only a replacement LCD panel for internal laptop use. The FQQ’s higher cost is justified by its plug-and-play functionality, magnetic mounting, and compatibility with multiple devices, but it remains substantially pricier than the FULLCOM screen, which serves a single, specific repair purpose.

Functionality: FQQ Offers Multi-Display Flexibility, FULLCOM Is a Replacement Panel

FQQ 15.6" Detachable Laptop Screen Extender functions as a portable, detachable monitor that can be used in dual or triple-screen setups, supporting horizontal and vertical rotation for varied workflows. It connects via USB-C or HDMI and works across Windows, macOS, Android, Chromebook, and gaming consoles without requiring drivers. In contrast, FULLCOM 17.3 inch Screen is not a standalone display; it is an internal replacement panel designed to replace a damaged laptop screen. It does not support external connections or multi-monitor configurations and must be physically installed inside a compatible laptop chassis.

Connectivity & Compatibility: FQQ Supports Modern Ports, FULLCOM Requires Internal Fit

FQQ 15.6" Detachable Laptop Screen Extender uses USB-C and HDMI ports for direct connection to laptops and other devices, enabling plug-and-play operation with no driver installation. It supports a wide range of systems including M1/M2/M3 Pro/Max MacBooks, Windows machines, Android tablets, and gaming consoles. FULLCOM 17.3 inch Screen, however, has no external connectivity—it is designed solely for internal installation and requires a 30-pin connector located on the bottom left side of the laptop’s display assembly. Its compatibility depends entirely on matching the original screen’s model number, backlight type, size, connector, and resolution.

Build Quality & Portability: FQQ Features Rugged Magnetic Design, FULLCOM Is a Fragile Component

FQQ 15.6" Detachable Laptop Screen Extender boasts a sturdy aluminum alloy frame with magnetic snap-on clips, allowing tool-free attachment and secure transport. Its foldable design packs flat into a carrying case, weighing just under 5 pounds (≈2 kg), making it ideal for travel. The device is built for daily commutes and frequent use in various environments. FULLCOM 17.3 inch Screen, by contrast, is a fragile internal component with no protective casing or portability features. It must be handled carefully during installation and offers no mobility or external usability beyond being a replacement part.

Visual Performance: Both Offer FHD 1080P, But FQQ Has Superior Display Tech

Both FQQ 15.6" Detachable Laptop Screen Extender and FULLCOM 17.3 inch Screen deliver Full HD 1080p resolution (1920x1080). However, FQQ uses IPS technology with a 178° wide viewing angle, 1000:1 contrast ratio, and 60Hz refresh rate, resulting in brighter, more vivid colors and better visibility from off-center angles. FULLCOM’s product description does not specify panel technology, viewing angle, or refresh rate, indicating it likely uses standard TN or basic IPS panels typical of older laptop screens. FQQ’s display is clearly optimized for visual clarity and user experience, while FULLCOM’s screen prioritizes functional replacement over image quality.

Use Case & Target Audience: FQQ Suits Mobile Professionals, FULLCOM Targets DIY Repairers

FQQ 15.6" Detachable Laptop Screen Extender is ideal for remote workers, digital creatives, developers, and students who need extra workspace on the go. Its ability to function as a portable, multi-screen setup transforms any laptop into a flexible workstation. It thrives in coffee shops, co-working spaces, or hotel rooms. FULLCOM 17.3 inch Screen is intended for users replacing a broken or malfunctioning laptop display, particularly those with Dell G3 3779, Precision 7730, Inspiron 5770, or similar models. It appeals to DIY technicians or individuals comfortable with internal laptop repairs and seeking a direct factory-equivalent replacement.

Which should you buy?

Choose the FQQ 15.6" Detachable Laptop Screen Extender if you need a portable, multi-display solution with modern connectivity, rugged build, and plug-and-play compatibility across Windows, macOS, and Android devices—especially if you value flexibility and mobility. It’s significantly more expensive at $289.99 but delivers a full-functioning external monitor system. Opt for the FULLCOM 17.3 inch Screen only if your goal is to replace a damaged internal laptop display, specifically for Dell G3 3779, Precision 7730, or Inspiron 5770 models, and you’re comfortable with internal installation. At $125.88, it’s nearly half the price of the FQQ, but it serves a completely different purpose—repair, not expansion.
