TANXJIA 10.5″ Portable Monitor, FHD 1920×1280 IPS Display
March 1, 2025
Discover the 10.5" Portable Monitor in our amusing review. Compact, powerful, and perfect for work or play, it's a must-have for tech-savvy multitaskers.
100% sRGB at 420 nits on a 10.5-inch screen that draws just 10W. TANXJIA’s JG105F packs 1920×1280 resolution into a compact IPS LCD panel with a 3:2 aspect ratio, 170-degree viewing angle, 5ms response time, HDR, built-in speakers, eye care technology, and a haze 25% anti-glare finish. It weighs 2.2 lbs, measures 14 x 8.8 x 0.4 inches, draws 10W at 5V, and connects via dual USB-C ports and one HDMI port. Compatible with laptops, MacBooks, Switch, Steam Deck, tablets, smartphones, and PS5/PS4. The 3:2 aspect ratio is the standout detail here. While most portable monitors use 16:9 or 16:10, the 3:2 ratio provides significantly more vertical screen space relative to width, which changes how documents, web pages, and productivity applications feel on a small screen.
Display: 1920×1280 with 3:2 Aspect Ratio
The 3:2 aspect ratio is what makes this monitor different from virtually every other portable display on the market. Most monitors use 16:9 (wider, less tall) or 16:10 (slightly taller). At 3:2, the screen is proportionally taller, showing more vertical content per inch of width. For documents, web pages, email, and code, this means more visible lines without scrolling. Microsoft Surface devices use 3:2 for the same reason, and pairing this monitor with a Surface creates a matched dual-screen experience.
1920×1280 resolution on a 10.5-inch screen produces high pixel density. Text is sharp, fine details are resolved, and the compact size doesn’t sacrifice clarity. The IPS LCD panel delivers consistent color across a 170-degree viewing angle, which is slightly narrower than the 178 degrees on larger IPS monitors but adequate for the personal viewing distance that a 10.5-inch screen demands.
420 nits brightness is well above the portable monitor average of 250-350 nits. The higher output keeps the screen readable in bright offices, near windows, and even in outdoor settings where lower-brightness monitors wash out. The haze 25% anti-glare finish reduces reflections while preserving color vibrancy, striking a balance between the glare resistance of matte panels and the color punch of glossy ones.
100% sRGB ensures accurate color reproduction. HDR enhances highlights and shadows in compatible content. Eye care technology reduces blue light and flicker for extended viewing comfort.
Connectivity: Dual USB-C with Power Pass-Through
Two full-function USB-C ports provide flexible connectivity. Connect your device with a single USB-C cable that carries both video and power. Or use one port for display and the other for power pass-through from a separate charger, ensuring the monitor receives consistent power without draining your laptop. This dual-port configuration is more versatile than single-USB-C monitors that force you to choose between single-cable convenience and reliable power delivery.
One HDMI port extends compatibility to gaming consoles, desktop PCs, and devices without USB-C video output. The monitor draws 10W at 5V, which is low enough for most laptops to power via USB-C without strain.
Compatible with laptops, MacBooks, Nintendo Switch, Steam Deck, tablets, smartphones, and PS5/PS4. Built-in speakers provide audio without external accessories.
Build: Ultra-Slim at 10.5 Inches
At 14 x 8.8 x 0.4 inches and 2.2 lbs, the TANXJIA is compact enough for any laptop bag, backpack, or carry-on. The 10.5-inch screen size keeps the footprint smaller than most tablets while providing a dedicated external display. The 0.4-inch profile adds minimal thickness when packed alongside a laptop.
2.2 lbs is heavier than expected for a 10.5-inch monitor. For comparison, some 15.6-inch monitors weigh less. The weight may include a built-in stand or thicker build construction, but TANXJIA doesn’t specify stand details in the listing.
Power Efficiency: 10W
10W power consumption at 5V means the monitor runs efficiently on USB-C power from most laptops. For users who work on battery power at cafes, airports, and co-working spaces, the low power draw extends combined laptop-and-monitor operating time. The dual USB-C port design allows supplemental power from a separate source when needed.

- 2.2 lbs is heavy for a 10.5-inch monitor (some 15.6-inch monitors weigh less)
- 170-degree viewing angle is narrower than the 178 degrees on most IPS panels
- 5ms response time is adequate but not gaming-tier

Who Is This Monitor For?
Surface users who want a matched 3:2 second screen. Microsoft Surface devices use 3:2 aspect ratio. Pairing this monitor with a Surface creates a visually consistent dual-screen setup where both displays share the same proportions. Content looks the same on both screens rather than shifting between different aspect ratios.
Document-heavy professionals who spend their day in email, Word, PDFs, and web applications. The 3:2 ratio shows more vertical content per screen inch than 16:9 monitors, reducing scrolling. At 420 nits with anti-glare, the display stays readable in bright offices and near windows.
Ultra-portable travelers who want a compact second screen with high brightness and accurate color. At 10.5 inches with 420 nits and 100% sRGB, the TANXJIA provides a bright, color-accurate display in the smallest form factor. The 10W power draw preserves laptop battery life during unplugged use.
Steam Deck and Switch owners who want a compact external display with HDMI and USB-C connectivity. The 10.5-inch size keeps the setup portable while upgrading resolution and brightness beyond built-in handheld screens.
Skip this monitor if you need a large display for multi-window productivity, if you need the lightest possible weight for a 10.5-inch screen, or if you need a manufacturer warranty beyond Amazon’s standard return policy.
Final Verdict
TANXJIA built the JG105F around an unusual choice: the 3:2 aspect ratio. While every competitor defaults to 16:9 or 16:10, the 3:2 panel delivers meaningfully more vertical screen space on a 10.5-inch display where every pixel of height matters. Layer on 420 nits brightness (above average), 100% sRGB, dual USB-C with power pass-through, HDR, and 10W efficiency, and the result is a small monitor with specs that punch well above its size class.
The 2.2 lbs weight is the unexpected tradeoff. For a 10.5-inch display, it’s heavier than anticipated. For buyers who prioritize the 3:2 aspect ratio, high brightness, and color accuracy in the most compact portable display format available, the TANXJIA addresses a niche that the 16:9 majority ignores entirely.
