Key Specifications
Screen size: 10.1 inch diagonal
Resolution: Ideally 1280 × 800 (HD/HD+) for good clarity. Some cheaper models use 1024 × 600.
Aspect ratio: 16:9 or 16:10 (16:10 gives slightly more vertical space)
Panel type: TFT LCD (often with LED back‑lighting)
Brightness: ~250–400 cd/m² (for indoor photo‑frame use, 250+ is acceptable)
Contrast ratio: Around 500:1 to 1000:1 — ensures decent depth in images
Viewing angle: Wide viewing angle preferred (e.g., ~85°/85°/85°/85°) so photos look good from off‑angles
Video input / interface: For a photo‑frame function you may want at least HDMI or USB input. Some monitors also include VGA/AV/BNC etc.
Power: Usually DC input (e.g., 12 V) or USB powered — ensure compatibility with your power source
Build form: Portable size, lightweight, optionally with built‑in speakers (if you might also display slideshows with sound)
If the monitor is purely for displaying photos (rather than interactive computer use), you might not need ultra‑high refresh rate or gaming features.
If it doesn’t have a built‑in photo‑slideshow mode, you might need an external player or computer/USB drive hookup.
Consider wall‑mount or tabletop stand form factor if you’re placing it as a photo frame.
Power consumption: Portable monitors may draw more than typical photo‑frames—check standby or sleep features.
If you’ll view in daylight or brighter rooms, higher brightness makes a difference.
