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 75MRGB88B9B suited for – and who isn't it for?

Straight talk: The right choice if you want a TV that's equally good at film and gaming, in the popular 75-inch size. If you have a darkened home cinema room focused on perfect black, also take a look at OLED. For cinema sound, plan for a soundbar.

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.

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.

Is the 75MRGB88B9B good for movies too, or only for gaming?

Both. Precision Dimming, Dolby Vision and 100% DCI-P3 deliver a high-contrast, color-accurate cinema picture; the 144 Hz and 0.1 ms come on top for gaming. It's a full-fledged movie TV with gaming speed built in – for cinema sound, a soundbar is the best addition.
