lg43uq8040

What’s the Deal with the lg43uq8040?

The model number might not roll off the tongue, but the lg43uq8040 has what matters: 4K resolution, a capable processor, and smart TV functionality running on LG’s webOS platform. Out of the box, it handles streaming apps like Netflix, Hulu, and Disney+ without the need for any thirdparty devices.

At 43 inches, this TV is wellsized for most living rooms, bedrooms, or as a secondary screen in a den. It’s also compact enough for apartment dwellers and students who want value without sacrificing image quality.

Picture Quality Without the Nonsense

Don’t expect OLEDlevel performance, but the 4K UHD screen performs above average for its pricing bracket. LG throws in their a5 Gen5 AI Processor, which boosts clarity, tone mapping, and upscaling for non4K content. Colors are decently vibrant, blacks are passable, and motion is smoother than you’d guess at this price.

For regular viewers—cable, streaming, YouTube—it’ll more than hold its own. The screen is edgelit, not fullarray, so black levels won’t match $1000+ TVs, but that’s expected. You’re getting clean detail, natural color processing, and minimal motion blur.

Smart Features That Actually Matter

LG’s webOS is one of the better smart TV operating systems. It’s not flashy, but it’s fast, and it works. Navigation feels intuitive with the remote’s scrollwheel design—a lowkey very useful detail.

Voice assistants are baked in (Google Assistant and Alexa), and there’s Apple AirPlay support too. You can cast from devices, mirror screens, or control media with your voice. Setup is quick, updates run in the background, and app support is deep enough that you won’t find yourself needing external streamers.

Gaming and Input Performance

Gamers won’t get HDMI 2.1 or 120Hz refresh here—this isn’t a highend panel—but what you do get is low input lag and ALLM (Auto Low Latency Mode). Plug in a PS5, Xbox, or Switch, and the TV adjusts automatically to optimize input response.

It’s a solid screen for casual gaming. Competitive esports players will want faster panels, but for storydriven games and casual multiplayer sessions, the response is tight enough.

Sound — It’s Fine

The 20W dual speaker setup is average, which is exactly what you’d expect in this range. Dialogue is crisp and volume fills smalltomedium rooms without stress. But if audio depth matters to you, plan on pairing it with a soundbar or speaker system.

Builtin AI Sound adapts audio based on the content you’re watching, which is nice. It won’t create surround effect or thunderous bass, but it will punch above “tinny TV speaker” expectations.

Design: Basic, Clean, No Fuss

Visually, the lg43uq8040 looks modern. Thin bezels, unassuming footprint, standard VESA wallmount compatibility. It’s not making any luxury statements and that’s the point. It’s not here to stand out—it’s here to work well and stay out of your way.

You get two legs for stand mounting, or pop it on a VESA bracket and you’re all set. Ports are positioned logically and include everything essential: 3 HDMI (one with eARC), 2 USB, Ethernet, optical audio, and antenna input.

Who It’s For

This TV hits the mark for anyone who:

Wants 4K without overpaying. Streams everything and needs fluid, smart integration. Games casually and wants responsive input performance. Lives in a smaller space or wants a second TV. Doesn’t want to fiddle with setup or addons.

If you’re budgetconscious but still expect things to run smoothly, this model is easy to recommend.

What’s Missing?

No Dolby Vision. No local dimming. No premium HDR formats (it supports HDR10 and HLG only). And, like most TVs at this level, sound isn’t immersive without an addon speaker. For those wanting more cinematic experiences or bleedingedge features, yeah—you’ll need to spend more. But most of those belong in a totally different price league.

The Bottom Line

The lg43uq8040 strikes a practical balance—it’s not trying to be the best TV ever made. Instead, it’s ticking the boxes most users actually care about: resolution, functionality, price, and reliability. Add in LG’s consistently solid software, and you’ve got a nofuss 4K option that won’t disappoint.

If you’re hunting for your first 4K TV or upgrading from an aging HD screen, it’s a solid buy. Simple, sharp, and smart—just how most TVs should be.
