I know why your TV is slow ‣ Diverse Daily

Your TV is no longer just an appliance like a microwave or a dishwasher. While it’s true that any TV you buy these days will be able to handle everything from Netflix to cable broadcasts to a PlayStation 5, you can have a radically different experience depending on a TV’s specs. The gap between watching The Shining on a 32-inch, 720p SDR TV versus a 70-inch 4K set with Dolby Vision might feel similar to watching it on a VHS tape versus watching it in the theater.

There are a variety of specs you need to pay attention to. Something that even a lot of home theater enthusiasts forget, however, is the concept of response times. They don’t necessarily have to be your priority — but as TVs become far more than a way of watching movies and shows, they should certainly be on your radar, and they’re one of the primary advantages of OLED. I’m sure it won’t take long to see what I mean.

What is response time, and why does it matter on a TV?

Let’s cut to the chase, here. Response time is how quickly individual pixels are able to transition from one color to another, measured in milliseconds (ms). That might sound remarkably close to the notion of refresh rate, but the latter is a metric of how fast the entire display is able to cycle, measured in hertz. I’d say refresh rates are ultimately more important, but I’ll talk about that in the next section.

Response times matter for a few reasons, the chief one being motion blur. When fast action is occurring onscreen — such as punching or kicking, or a race car whipping around a curve — slow response times can lead to a “ghost” image trailing behind some objects. Slow is a relative term, since the extent of this problem is much lower in 2026 than it was 2006, but it can still be distracting. And regardless, the faster response times are, the crisper all motion is going to look, including camera pans and zooms.

Something very significant in the modern age is lag. Response time isn’t directly connected to input lag, to be clear — but if your TV is already taking 50ms to render an image, a 14ms response time will make things feel even worse.

Honestly, lag doesn’t have any impact on movies or shows beyond the distractions I’ve mentioned. Where it really comes into play is with anything interactive, above all games. Ghosting makes it harder to aim in shooters like PUBG, or simply keep track of what’s going on amid the deliberate overload of Sektori. In games that demand precision timing to make progress — which is many of them, obviously — instant visual feedback is essential.

Both input lag and response times have to be kept in check. On paper, a 0.06-second delay might sound trivial. In a game like Hollow Knight, though, that could mean the difference between beating a boss or spending the next hour trying to do it again, since you also have to account for your brain’s ability to process that delay and react with a controller. Controllers add their own input lag.

You’ll also find poor response times a hassle if you’re connecting a PC for productivity. They might only be a minor irritation for some users, for instance making webpages harder to decipher when you’re scrolling. Others absolutely need clarity for their work however, say if they’re using a TV for photo or video editing. A high-end monitor may be preferable for most productivity tasks, but professionals have to make do with whatever they have on hand.

The good news in this regard is that a lot of TVs already have reasonable specs. It’s common for recent LCDs to have response times of 10ms or less, which is plenty for most gamers and movie fans. In fact it’s sometimes possible for performance to be pushed too far, resulting in stutter, or two related problems, overshoot and undershoot. Those are caused by an overdrive circuit being used to accelerate LCD response times. If something goes wrong, the higher voltage can result in false-color outlines.

This is where OLED comes into play. Because OLED TVs use self-emissive pixels without liquid crystals (the “LC” in LCD), their response times are inherently faster, no overdrive required. How fast, you ask? You’re unlikely to find a 2026 model slower than 1ms, and a few color transitions may happen in as little as 0.1 to 0.2ms, depending on the exact TV you’re talking about. Essentially, if you want the tightest possible response, OLED will always beat LCD, including newer variations like mini-LED. There are reasons you might prefer mini-LED, but those are separate.

Why refresh rates are a bigger concern

The ultimate arbiter of motion

For perfectly clear motion, response times and refresh rates need to align. At 120Hz, a new frame is being rendered approximately every 8.33ms. If response times are higher than that threshold, colors will still be shifting by the time the next frame is due, producing blur. As I’ve said, though, response performance frequently sits within a safe window these days, and far greater issues exist on the other side of the fence.

All the content you consume operates at a variety of different framerates. Movies and “prestige” TV shows typically display at 24fps (frames per second), while most other videos play at 30fps. Some YouTube videos (such as PEV rides) can hit 60fps, and the only limit on games and other PC/console apps tends to be processor performance. Your PC would render Cyberpunk 2077 at 120fps or higher if it wasn’t struggling to keep up with photorealistic models and ray-traced lighting.

If framerates exceed refresh rates, or vice versa, the result is visual artifacts. On a TV locked to 60Hz, playing 24fps content creates judder, since 60 divided by 24 doesn’t produce an even number. Without compensation, any refresh surplus can lead to stuttering — and when framerates top refresh rates, there’s the possibility of screen tearing, in which multiple frames are smashed together.

Realistically, any TV you buy these days should not only support 120Hz refresh rates or better, but an HDMI 2.1 feature called VRR. This matches refresh rates to framerates on the fly. I’d argue that it’s non-negotiable if you’re connecting a PC or console, since an app could be sitting at 62fps one moment, then dip down to 32fps for a few seconds before bouncing back somewhat to 50fps. As a bonus, HDMI 2.1 also includes ALLM, which enables Game Mode automatically when a PC or console is connected. That eliminates redundant post-processing to minimize input lag.

Let me drop a note here about my personal nemesis, motion smoothing. All TVs offer some variant of the feature to counteract blur and judder, but it should always be disabled, or at least dialed back as far as possible. That’s because it relies on artificially-generated frames inserted to keep up with refresh rates. With 24fps content, this kills the natural blur you’re anticipating, leading to the infamous “soap opera effect.” That gets its name from making $200 million blockbusters look like they were shot with cheap broadcast cameras, killing immersion. In theory, Dolby Vision 2 and HDR10+ Advanced should help salvage smoothing, but I’ll need to see that myself to believe it.
