LG 86MRGB88B9B

The LG 86MRGB88B9B is an 86-inch 4K gaming TV with Mini RGB evo technology (Mini LED), 144 Hz, 0.1 ms and alpha 8 Gen3 processor – Precision Dimming and 100% color coverage for gaming and film on one screen.

86 inches (218 cm) of gaming big-screen: a playing surface no monitor offers – for the large living room with plenty of seating distance.

Why the LG 86MRGB88B9B?

Because it combines gaming speed with Mini LED picture quality. 144 Hz, 0.1 ms, NVIDIA G-Sync and AMD FreeSync Premium deliver a smooth picture without tearing; Precision Dimming controls the brightness zones for deep contrast. The RGB technology covers 100% DCI-P3 and Adobe RGB. webOS 26 makes it a full smart TV with all streaming services.

What you get

A large gaming screen with TV comfort: 4K with 144 Hz and 0.1 ms, G-Sync and FreeSync Premium, plus Dolby Vision Gaming and Dolby Atmos. Tuned for both console and PC – HDR gaming and cinema from one device.

Who is the 86MRGB88B9B suited for – and who isn't it for?

Straight talk: For large, bright rooms and gamers who want a big screen without any speed compromise. In a small room the surface overwhelms – you'd sit too close. The flat body doesn't deliver deep bass, so plan a soundbar or speakers for full cinema sound.

What's the difference between the MRGB88 and MRGB96 series?

The 88 series (Mini RGB, alpha 8) is tuned for gaming: 144 Hz, 0.1 ms, G-Sync. The 96 series (Micro RGB, alpha 11) is the color flagship with triple color coverage including BT.2020 and more picture processing power. In short: 88 = gaming performance, 96 = maximum picture quality.

Our verdict

The big gaming cinema: 86 inches of Mini RGB with 144 Hz and G-Sync – blockbusters and games on an XXL surface. At HD Zürisee in Wädenswil, we set up picture and gaming mode with you.

Frequently asked questions

Do I need a specific console or graphics card for 144 Hz?

For full 144 Hz in 4K you need a suitable source (a current gaming PC). Consoles like PS5 and Xbox Series X deliver up to 120 Hz – the TV makes full use of that too. Via HDMI 2.1, both are directly connected.

How much seating distance does an 86-inch TV need for gaming?

For 86 inches, around 2.5 to 3.5 meters is comfortable – for gaming you can sit a bit closer to immerse yourself in the picture, for movies a bit further back. Too close and the surface quickly feels overwhelming. We're happy to look at your room and the ideal distance with you.
