How it works
1. Open it on the TV
Find the web browser on your Smart TV or streaming device and go to tv-test.com. The page notices it is on a television and switches to a large, high contrast layout you can drive with the arrow keys on your remote.
2. Run a test
Pick a test and it starts immediately. There is nothing to install, no sign-up wall, and no waiting. Most tests are finished in a couple of seconds.
3. Check the result
You get a clear answer first, then the reason behind it, and the technical detail last if you want it. No wall of numbers to figure out on your own.

The TV Tests
Grouped by what they check. Every one runs in your TV's own browser.
Capability & connection
TV Capability Test
The big one. Resolution, HDR signalling, color gamut, video and audio codecs, copy protection and audio output, all explained in plain language.
StreamingTV Internet Speed Test
Measure the real download speed reaching the TV, and see whether it is enough for 4K, HDR or Full HD on each major service.
CapabilityHDR Test
A focused check of just HDR signalling and color gamut, faster than the full capability test.
CapabilityCodec Test
Which video and audio formats your TV's browser can actually decode, on their own page.
CapabilityDRM Test
Check whether Widevine, PlayReady or FairPlay is reachable, without running the whole capability test.
Picture quality
Screen Resolution Test
What resolution is your TV really running, and is it truly 4K?
PictureCalibration Patterns
Color bars, grayscale, black level and geometry patterns for setting a TV up properly.
PictureColor Banding Test
Smooth gradients reveal banding and where your screen runs out of steps.
PictureTV Motion Test
Moving patterns reveal motion blur, 24p judder and dropped frames, and the soap opera effect.
PictureRefresh Rate Test
How many frames per second the browser really delivers, and why a 120Hz TV reports 60.
PictureOverscan & Screen Fit
Is your TV quietly cropping the edges of the picture? Find out how much is missing.
Screen faults
Dead Pixel Test
Full screen colors find dead, stuck and bright pixels, plus a stuck pixel fixer.
PictureStuck Pixel Fixer
A flashing box over a stuck pixel can knock it back to life. Honest about the odds.
PictureBacklight Bleed Test
Pure black fields expose light leaking around the edges of an LCD panel.
PictureScreen Uniformity Test
Flat fields reveal the dirty screen effect and blotches. Why sport looks patchy.
PictureBlooming Test
Bright shapes on black show the halos of local dimming. The mini-LED question.
PictureFull Screen Colors
Black, white, red, green, blue and gray, each on its own page, with what it reveals.
PictureOLED Burn-in Test
Full field colors reveal image retention and burn-in on an OLED, with a screen wash for temporary retention.

How to test a TV
To test a TV, run its built-in self-test from the settings menu if it has one, then open the tests on this site in the TV's own browser and work through them in order. The full check takes about ten minutes, installs nothing, and shows whether a fault sits in the TV, the cable or the app.
- Capability: What the set really supports - resolution, HDR, codecs, copy protection.
- Pixels: Nine solid colors expose dead and stuck pixels; a stuck one may respond to the fixer.
- Backlight: Dark-room check for edge glow on an LCD, or burn-in on an OLED.
- Gradients: Smooth fades reveal banding.
- Motion: Blur, judder and the soap opera effect.
- Edges: Whether the TV crops the picture.
- Sound: Both channels, rattles, and lip sync.
- Speed: Whether the internet reaching the TV is enough for 4K.
The full walkthrough, including each brand's built-in self-test menu, is in the guide: How to test your TV.

Why we tell you what we cannot measure
Plenty of TV testing sites will happily report a number they have no way of knowing. We would rather be the one you can trust.
A web page cannot measure HDR brightness in nits. It cannot tell you your panel's true refresh rate, because browsers are usually capped at 60 frames per second regardless of the screen. It cannot reliably read your Widevine security level. And it can only see what the browser supports, which is not the same as what your TV's Netflix app supports.
So we say all of that, right next to the results, instead of quietly guessing. Where a browser genuinely cannot answer, we show "unknown" and explain why, rather than inventing a figure.
Questions people ask
How do I test my TV?
Open tv-test.com in the television's own browser and work through the tests in order: The Capability Test for resolution, HDR and codecs, the Dead Pixel Test and Backlight Bleed Test for the panel, then motion, overscan, sound and internet speed. The whole pass takes about ten minutes, needs no downloads and no account. Samsung, LG and Sony sets also have a built-in self-test in the settings; the guide how to test your TV lists the exact menu paths.
Why does my new TV look worse than my old one?
Usually it is the settings, not the screen. New TVs leave the factory with motion smoothing switched on, which gives films and drama a cheap, hyper-smooth look known as the soap opera effect. A punchy store demo mode, and picture edges quietly cropped by overscan, add to it. Turn motion smoothing off first, then check that nothing is being cut off. Our guide to the soap opera effect has the exact setting for every brand, and the TV Motion Test and Overscan and Screen Fit test let you see both on your own screen.
How can I tell if my TV is really 4K and HDR?
The box and the menu can both be optimistic. The TV Capability Test reads the resolution your TV actually reports, along with the HDR formats and video codecs its browser supports, and explains each one in plain language. It cannot measure HDR brightness in nits, and rather than guess it tells you so.
How do I check a second-hand or ex-display TV before I buy it?
Open the TV's own browser on the set and run four quick checks: The Dead Pixel Test for stuck or dead dots, the Backlight Bleed Test for glow in a dark scene, the TV Capability Test for resolution and HDR, and the TV Speaker Test for a rattle or a dead channel. Ten minutes tells you more than the listing does.
Is my internet fast enough for 4K streaming on my TV?
As a rule, 4K needs about 25 Mbit/s per stream and Full HD around 5, and that is per device rather than per household. The TV Internet Speed Test measures the real speed reaching the television, not a phone in another room, and tells you which quality each major service can hold.
How do I find out which Smart TV I have?
If you are not sure whether your set runs Tizen, webOS, Fire TV, Google TV or something else, What TV Do I Have identifies the platform and app store from the browser. On many devices the model name is in the browser identification too, and the page decodes it; Samsung and LG browsers send none, and it says so honestly.
Is TV Test free, and what happens to my data?
Yes, it is free, with no account to create and no ads. Each test runs in your browser and its result stays there, so we do not receive or store your results. To see which tests people find useful and to keep the site working, we use analytics that record anonymous details like page views, your browser type, and the country you visit from, never tied to who you are and never sold. What we collect, and how it is handled, is explained in our privacy policy.
