Your PC to the big screen, in full quality.
Any video on your PC can go to any television in the house — in 4K HDR, with the subtitles you chose already on the picture. Here is what happens when you press cast, which TVs are supported, and what to do when something misbehaves.
Casting is not screen mirroring.
People use the words interchangeably, but they do very different things — and it is why mirrored video looks soft and stutters while cast video looks like the film.
Your PC captures whatever is on the display, compresses it into a live stream and throws it at the TV. Everything is re-encoded on the way, at whatever quality the connection can carry.
AIX Player hands the television the video itself and lets the TV's own decoder do the work. Nothing is captured from your screen, so no quality is thrown away in the middle.
Press cast, pick the TV, sit down.
Playing videos on your PC is free and unlimited, always. Casting is the premium part: 60 free minutes in total, once, which is long enough to try it properly on your own TV, and Pro lifts the limit for unlimited casting to every television you own. No adverts in either case.

Anything on your PC, an external drive, or a pasted link. Set the subtitle track and styling you want now — it travels with the picture.

Press the cast button
AIX Player scans the network and lists every television it finds, by the name you gave it, grouped by what each one can actually do.

Pick it and watch
The film appears within seconds. Your PC becomes the remote — play, pause, seek, volume and subtitles, all from the AIX Player window.
Devices appear on their own. Some sets ask for a one-time approval: a PIN on Fire TV and Apple TV, an on-screen Allow on LG and Samsung, and on Roku the free AIX Casting Receiver channel added once from your Roku account.
If it's in your living room, AIX Player can reach it.
Each family speaks its own protocol, and AIX Player speaks all of them — so you are not installing a different app for every screen you own.
Chromecast dongles, Google TV sets and any Android TV with Cast built in. The most common setup, and the smoothest.
Fire TV, Roku, Apple TV and NVIDIA Shield are each paired directly, using their own protocol rather than a generic fallback.
LG webOS, Samsung Tizen and Sony Bravia sets pair with what is already inside the television. Nothing to buy, nothing to plug in.
The oldest standard in the house, and still the most widely fitted. If a television is a few years old and connected, this is usually how AIX Player reaches it.

They reach the TV — every time.
This is the part that usually falls apart. A subtitle file sitting next to your video is invisible to the television, because it was never inside the video in the first place.
AIX Player draws the subtitles onto the picture before it leaves your PC. By the time the film reaches the TV the text is part of the image, so it shows on any television regardless of what that television supports.
The film starts anyway.
Televisions only understand a short list of video types. Hand one a film with an advanced picture track and a cinema surround soundtrack and it will usually refuse part of it — which is why casting so often ends in a black screen, or a picture with no sound. AIX Player converts only what is needed, frame by frame, while the film plays.
AIX Player asks the television what it can handle before sending anything, rather than starting and hoping.
Very often that is just the soundtrack, leaving the picture untouched at full quality. The work runs on the dedicated video hardware in your graphics card, frame by frame as the film streams — so nothing is saved to disk and you never wait for a conversion to finish.
Where the television supports HDR and 10-bit, that is what it receives. Nothing is downgraded just to get the film moving, and nothing is converted that did not need to be.
Four things fix almost everything.
Both devices must be on the same network — guest Wi-Fi and split 2.4/5 GHz networks keep them apart, and some routers have client isolation switched on. Check the television is awake, too.
Wi-Fi is nearly always the bottleneck. A wired PC frees the whole wireless channel for the television, which makes a real difference on high-bitrate 4K.
The television rejected the audio track — usually the studio surround mix from a disc rip. AIX Player converts it as it streams; switching to a stereo track in the film also fixes it instantly.
If Windows goes to sleep, the stream stops with it. On a laptop, plug it in before starting anything feature-length.
Put tonight's film on the big screen.
Install AIX Player, open a video, press cast. That's the whole setup.
