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 LCDOLED® Compatible with ASUS TUF Gaming FX505 FX505D FX505DD FX505DU FX505DT FX505DV Series FX505DV-ES74 15.6 inches FHD 1080P IPS LCD Display Screen Panel Replacement (120Hz - 40Pin Connector)

Price Difference: A Clear Cost Divide

The FQQ 15.6" Detachable Laptop Screen Extender is about 220% more expensive than the LCDOLED® screen replacement, priced at $289.99 compared to $89.98. This represents a difference of $199.01, making the FQQ nearly three times the cost of the LCDOLED panel. While the FQQ offers a multi-screen portable solution with advanced connectivity, the LCDOLED product is a single-purpose display panel replacement that costs less than one-third as much. The price gap reflects entirely different use cases—one is a full external monitor system, the other a direct hardware swap.

Functionality and Use Case: External Display vs. Internal Replacement

The FQQ 15.6" Detachable Laptop Screen Extender functions as a portable, dual or triple monitor setup that connects via USB-C or HDMI for plug-and-play use. It’s designed to extend your laptop’s workspace without altering internal components. In contrast, the LCDOLED® screen is a direct replacement for the original LCD panel inside an ASUS TUF Gaming FX505 series laptop. It does not function as an external monitor; it replaces the built-in screen and requires disassembly and installation. The FQQ enables flexible, mobile work environments, while the LCDOLED is strictly a repair part for a damaged internal display.

Connectivity and Compatibility: Plug-and-Play Versus Model-Specific Fit

The FQQ supports both USB-C and HDMI connections, enabling plug-and-play functionality across Windows, macOS (M1/M2/M3 Pro/Max only), Android, Chromebook, Surface, Linux, Switch, Xbox, and PS4—no drivers required. Its compatibility hinges on having a fully functional USB-C or HDMI port on the host device. The LCDOLED® screen, however, is compatible only with specific ASUS TUF Gaming FX505 models, including FX505DV-ES74, and uses a 40-pin EDP connector. It is explicitly incompatible with 30-pin connectors and requires professional installation. The FQQ offers broad cross-platform versatility, while the LCDOLED demands precise model matching and technical expertise.

Design and Portability: Travel-Friendly Monitor vs. Internal Component

The FQQ features a rugged aluminum alloy frame with magnetic snap-on clips, foldable design, and a carrying case, weighing approximately 5 pounds. It’s engineered for travel and daily commutes, allowing users to set up a multi-monitor workstation in coffee shops or hotels. The LCDOLED® screen, by contrast, is a flat panel with no built-in housing, bezel, or carrying case. It arrives as a standalone LCD panel with no additional accessories, requiring users to retain their original laptop parts for mounting. The FQQ is a complete, portable solution; the LCDOLED is a bare component meant for internal replacement.

Visual Performance: Refresh Rate and Panel Type

The FQQ displays a 1080P IPS panel with a 60Hz refresh rate, 1000:1 contrast ratio, and 178° wide viewing angle. It delivers vibrant colors and consistent visuals across angles, suitable for general productivity and media consumption. The LCDOLED® screen, also 1080P IPS, boasts a higher 120Hz refresh rate and 72% NTSC color gamut—ideal for gaming and fast-moving content. However, it is specifically designed for 120Hz systems and may not support 60Hz configurations. The FQQ’s 60Hz is standard for most tasks, but the LCDOLED offers superior motion clarity for gamers using compatible laptops.

Included Accessories and Setup Requirements

The FQQ comes with a complete kit: one monitor, a protective box, a carry bag, user manual, and a USB-C cable with USB-A connector. All components are included for immediate use. The LCDOLED® package contains only the LCD panel itself—no bezel, back cover, cables, tools, or instructions. Users must keep their original parts and possess professional installation skills. The FQQ is ready to use out of the box, while the LCDOLED requires significant technical effort and prior knowledge of laptop disassembly.

Which should you buy?

Choose the FQQ 15.6" Detachable Laptop Screen Extender if you need a portable, multi-screen setup for remote work, coding, or creative projects—especially if you value plug-and-play ease and travel-friendly design. It’s ideal for users seeking flexibility and modern connectivity. Opt for the LCDOLED® screen replacement only if your ASUS TUF Gaming FX505 laptop has a cracked or malfunctioning internal display and you’re prepared to replace it yourself. At $89.98, it’s significantly cheaper than the FQQ, but it serves a very different purpose: a repair part, not a display extension. If you're upgrading your workflow, go with the FQQ. If you're fixing a broken screen, the LCDOLED is the targeted solution.
