Overview
A bedroom wall or a small living room is where this set earns its keep, and the slim cabinet is shaped to sit close to one. The Direct LED panel lights the screen from behind in zones, while the Alpha 7 processor handles upscaling, tone mapping and the picture wizard that tunes settings from your own clips. webOS pulls the streaming apps and free channels into one place.
Buyers shopping at this size usually want a second screen that streams well without a soundbar and console stack behind it. The smart platform, AirPlay 2 and Google Cast cover that, and the gaming features are present in a basic form. What you give up is brightness headroom and motion smoothness, since the panel is edge-lit in zones and capped at the standard refresh rate.
Who it's for
A household that streams most nights and wants one remote to cover apps, casting and over-the-air channels. Console players who only need a standard refresh rate will be content. Anyone who needs a brighter panel for a sunlit room or a faster panel for twitch shooters should keep looking.
Pros and cons
- Smart platform covers major streaming apps
- AirPlay 2 and Google Cast built in
- Gaming features include VRR and FreeSync
- Filmmaker Mode preserves director settings
- Refresh rate limited to sixty hertz
- HDR10 and HLG only, no Dolby Vision
- Direct LED backlight, not full array
- Stand depth not listed for shelf planning
Performance notes
Picture quality here comes down to the processor rather than the panel. Upscaling and dynamic tone mapping clean up lower-resolution sources, and the backlight dims in zones behind the image, so dark scenes show some glow around bright objects. Motion holds together at the panel's native rate, and VRR reduces tearing when a console feeds it variable frames.

Frequently asked questions
Is the LG 43UA7700P a monitor as well as a TV?
No. It is a television with an ATSC and QAM tuner, a webOS smart platform and a remote, so it is built for broadcast and streaming rather than desktop use. A computer can feed it over HDMI, but it is not sold as a monitor.
How many devices can I connect at once?
There are three HDMI ports, two USB ports, plus Ethernet, Wi-Fi and Bluetooth. The HDMI ports are version 2.0, which is enough for 4K input at the panel's standard refresh rate.
