Samsung Q80D QN75Q80DAFXZA 75"

Big, bright, and smooth for gaming, but the HDR is a letdown. Get the TCL QM8K instead if you want real picture quality at this size.

The display itself is a standout, ranking near the top of our charts for size and clarity. The 120Hz Motion Xcelerator and FreeSync support make fast action look smooth, and the NQ4 AI Gen2 processor does a solid job upscaling older content. But here's the surprise: the HDR performance is mediocre at best. Quantum HDR+ sounds fancy, but the Direct LED backlight without local dimming means blacks get lifted and bright highlights don't pop the way they should. For a 2024 QLED at this size, we expected more.

The TCL QM8K Series 75QM8K is the direct threat here. It offers mini-LED backlighting with real local dimming, which crushes the Q80D's HDR performance for similar money. The Hisense U8 Series also beats it on contrast and brightness. On the OLED side, the LG C5 is smaller at 55 inches but delivers infinitely better picture quality if you can live with less screen. The Sony BRAVIA XR is the premium pick, but it costs way more. For most buyers, the TCL QM8K is the smarter 75-inch choice.

At around $1,049 USD for a 75-inch QLED, the price is tempting. But you're paying for size and smart features, not picture quality. If you want a big screen for casual viewing, sports, or gaming in a bright room, this is a solid deal. If you care about HDR movies or dark-room performance, save your money or look elsewhere.

The Samsung Q80D is a big, bright 75-inch QLED that nails the basics and then stumbles where it matters most. You get a gorgeous 4K panel with Quantum Dot color, a 120Hz refresh rate, and Samsung's slick Tizen smart platform. But the picture quality and HDR scores land in the bottom third of our database, which is a weird spot for a TV that looks this good on paper. The short version: it's a great living room TV for sports, gaming, and bright rooms, but movie nerds will notice the missing punch in dark scenes.

If you're shopping for a home theater centerpiece and care about HDR movies, this isn't it. The lifted blacks and weak contrast will bug you every time the lights go down. Go get the TCL QM8K or Hisense U8 instead. If you want OLED-level picture quality and can live with a smaller screen, the LG C5 is the move.

The Samsung Q80D is a good TV that should have been great. It's big, bright, and fast, with a smart platform we genuinely enjoy using. But the weak HDR and average picture quality hold it back from being a top pick. Buy it if you want a huge Samsung screen for gaming and everyday viewing. Skip it if you care about movie nights in a dark room.
