Your PC to the big screen.
Supported videos on your PC can be cast to AIX Player’s seven TV families — up to 4K HDR where the source, PC, network and TV support it, with selected subtitles rendered 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 supported videos on your PC is free and unlimited. 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 supported TVs. No adverts in either case.
In AIX Player 3.0.6, Jellyfin, Emby and Plex videos play on your PC; casting media-server videos is not supported. Network shares (SMB / NAS) can be browsed and played on your PC for free, with no time limit. These casting steps are for supported local files. Read about media servers.

Open your video
Open a supported local file on your PC or an external drive. 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 the supported televisions it finds, by device name and family.

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 uses its own protocol. AIX Player supports the seven families below, so you do not need a separate Windows app for each one.
Chromecast dongles, Google TV sets and Android TV devices with Google Cast built in. This is a common setup and needs no receiver app.
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.

Subtitles travel with the picture.
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 supported subtitle formats onto the picture before it leaves your PC. By the time the video reaches a supported TV, the text is part of the image, so the television does not need to read the subtitle file itself.
AIX Player converts when needed.
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.
Often that is just the soundtrack, leaving the picture untouched. Video conversion can use supported Intel, AMD and NVIDIA graphics hardware; on Qualcomm, only H.264 encoding is hardware-assisted. Other stages use the processor. Conversion happens frame by frame while the video streams, and no converted copy is saved to disk.
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 to check first.
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 may also resolve it.
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.
