Before you try it.

An app for your Google TV, Android TV or Fire TV that plays up to 8 live games at once, each as its own tile, from the services you already pay for. You pick which game is big and which one you hear, with the TV remote or the free iPhone app (coming soon).

YouTube TV’s multiview shows up to 4 channels, all from YouTube TV. QuadCue plays up to 8, from any channel in your guide, with Peacock, Prime Video and Paramount+ beside them. And you can rewind or pause one game while the rest stay live. See the full comparison.

Yes. QuadCue plays the services you already pay for, signed in with your own accounts. It doesn’t sell or include any channels.

No. QuadCue is for watching live. Each game keeps its last few minutes so you can rewind; recordings stay with your service’s own DVR.

Google TV and Android TV devices on Android 9 or later, and Fire TV devices on Fire OS 7 or 8. NVIDIA SHIELD TV is the best. It doesn’t run on Roku, Apple TV, Samsung or LG TVs, or Amazon’s newest Fire TV Sticks, which run Vega OS (Stick 4K Select, Stick 4K 3rd gen, Stick HD 2nd gen).

Up to 8. NVIDIA SHIELD plays all 8 at full quality. Most other boxes, sticks and smart TVs play 6 to 8, and a few slower ones fewer: the game you hear and the big game stay sharp, and the rest play at a lower picture quality. QuadCue tests your TV the first time it opens and picks the number for you.

Get the free Downloader app (you can send it to your TV from your phone), turn on developer mode, then type the code 3916187 in Downloader (or quadcue.com/tv). It takes about five minutes the first time, and QuadCue keeps itself up to date. Step-by-step setup.

We publish QuadCue ourselves, so it installs with Downloader instead of an app store. Same app, and it updates itself.

Roughly 25 to 35 Mbps for a full screen of games: a sharp game uses about 3 to 8 Mbps, small tiles less. Ethernet or strong 5 GHz Wi-Fi works best, and Picture › Lightest in Options uses the least.

Yes. Press OK on any game and its sound comes on; the red frame shows the one you’re hearing. Press OK again for full screen.

Yes. Skip back 10 seconds, rewind or pause any game while the others stay live, then jump back to live. Each game keeps up to 10 minutes on SHIELD, a few minutes on smaller TVs.

Yes. Hold OK on a game to make it the big one, or pick a layout: Same size, One big with the others on the side or below, or Two big on top.

No. The TV remote adds games, changes layouts and chooses which game you hear, and YouTube TV signs in with any phone’s camera. Prime Video signs in with Amazon’s code on any phone or computer. The free iPhone app makes it all quicker, and it’s how you sign in to Peacock and Paramount+. It’s coming soon to the App Store.

Not yet. With an Android phone, the TV remote does everything and your phone’s camera signs you in to YouTube TV and Prime Video. Peacock and Paramount+ sign in through the iPhone app.

YouTube TV and Prime Video play side by side today. Peacock and Paramount+ too, once the QuadCue iPhone app is out (coming soon). HBO Max, Hulu + Live TV, Fubo, Sling, DirecTV Stream and Apple TV are coming.

YouTube TV and Prime Video show a QR code on the TV: scan it with any phone’s camera, sign in on the service’s own page, and you’re done. Peacock and Paramount+ sign in from the QuadCue iPhone app (coming soon), also on the service’s own page. Once per TV, no typing with the remote.

Each game is its own stream from your service, played with your own account. YouTube TV has played all 8 at once on one TV in our testing. Peacock allows 3 at once: QuadCue says so before you add a fourth. If a service ever turns a stream down, that game’s tile tells you.

No. Your password goes only to the service, on its own sign-in page. QuadCue’s servers never see your passwords or your sign-ins.

$5.99 a month or $49 a year, for up to 3 TVs in your home. The iPhone app is free (coming soon).

Every TV plays free for 7 days from the first time QuadCue opens on it. No card, no account. When it ends, the TV shows a QR code to subscribe.

Yes, in your account › Manage billing. QuadCue keeps working until the end of the period you’ve paid for.

It renews every month or year until you cancel, plus tax where it applies. Questions about a charge? Ask us. Cancel before it renews and QuadCue keeps working until the end of what you’ve paid for.

No. Your subscription is the email you used at checkout. To sign in here, we email you a 6-digit code.

Sign in to your account and add a TV with the code it shows (Options › Subscription), or remove one to make room. Up to 3 TVs.
