PULTEVENT
Connecting a laptop to a TV for party games: 6 setups that work
Twenty to eight. Guests are due at eight. The laptop is plugged into the TV, the TV says No Signal in a grey box that drifts slowly around the screen, and the host is on their knees behind the entertainment unit with a phone torch in their teeth, reading the labels on four identical ports. It's HDMI 3, as it turns out. It's always the one you try last.

Getting a laptop onto a TV is a five-minute job once you've done it, and a twenty-minute panic the first time. This page is the version I wish someone had given me before my first house party with a game on the telly: which cable, which setting, where the sound goes, and what to test before the doorbell rings.
The setups below work for PULTEVENT and for anything else that runs in a laptop browser. The laptop keeps the host console, the TV shows the stage, and guests play on their phones via a QR code. The one thing a cable can't fix is internet: the laptop and every guest's phone need a connection, so the Wi-Fi password belongs on your checklist next to the HDMI lead.
6 laptop-to-TV setups, from living room to function room
1 Laptop with HDMI straight into the TV
The simplest version. A standard HDMI cable from the laptop's HDMI port to any free HDMI input on the TV.
How to run it. Note which input number you plug into, then pick exactly that input on the remote.
Nine parties out of ten need nothing more than this.
2 USB-C laptop with an adapter
Many thin laptops have no HDMI port. A USB-C to HDMI adapter, or a small hub with an HDMI socket, does the job.
How to run it. Check that the USB-C port carries video (often shown by a small display or lightning symbol next to it, or in the laptop's specs). Buy the adapter a week early, not on the day.
The adapter is the item most often left at home. Keep it in the laptop bag permanently.
3 Laptop to a venue projector
A long HDMI run from the host table to the projector, which may be on the ceiling or across the room.
How to run it. For longer runs buy a decent quality cable, and tape it down where people walk. Ask the venue if a wall plate already runs to the projector.
In a hall, the projector is usually where the screen is, and the host table is where the power is. The cable bridges the two.
4 TV for picture, speaker for sound
The picture goes to the TV over HDMI, but the laptop's sound goes to a separate speaker or the venue's sound system through a jack or USB audio cable.
How to run it. In the laptop's sound settings pick the speaker as the output, not the TV. Test the volume from the back of the room.
TV speakers are fine for a dinner party quiz and hopeless for a dance battle.
5 One laptop, two screens in a big room
An HDMI splitter takes one output from the laptop and sends the same picture to two TVs, say one at each end of a long room.
How to run it. Both TVs will show the same stage picture. Set both to the same resolution if the splitter lets you.
Nobody ends up watching the game from behind a pillar.
6 No TV at all: a video call
For relatives abroad or a remote team, share the stage window in a video call. Everyone sees the stage on their own screen and still plays from their phone.
How to run it. Share only the stage window, not your whole desktop, so the host console stays private.
The same games work for people who couldn't come, without a separate setup.
HDMI is the answer
A cable beats wireless casting for games: no lag, no dropouts, no pairing menus.
Extend, don't mirror
The TV becomes a second screen, so guests never see your scores, notes or messages.
Sound comes along
HDMI carries audio. Choose the TV as the output and the music plays through it.
Test it the day before
Ten minutes the night before saves the twenty-minute panic at twenty to eight.
Extend or duplicate: the setting that matters most
When you plug a laptop into a TV, it usually starts by mirroring: the TV shows an exact copy of the laptop screen. For a party game you want the other mode, extend, where the TV acts as a second monitor to the right of the laptop. Both Mac and Windows laptops have this option in their display settings, and Windows also offers a quick shortcut menu for projecting.
In extend mode, drag the stage window across onto the TV and make it full screen. The laptop screen keeps the host console with the scoreboard, the next question and your notes. The guests only see what you send them.
Mirroring does work in a pinch, but then the room sees every click, every menu and every message that pops up in the corner.
Where the sound goes
HDMI carries sound as well as picture, and most laptops switch audio to the TV automatically. If the music is still coming from the laptop's tiny speakers, open the sound settings and choose the TV (it's usually listed by its model name) as the output device.
Turn the laptop's own volume up to maximum and control the level with the TV remote or the speaker. It stops a situation where the TV is at full volume but the laptop is sending a whisper.
The edges are cut off, or everything is blurry
Cut-off edges mean the TV is zooming the picture slightly, a leftover habit from broadcast TV called overscan. In the TV picture menu look for aspect or picture size and choose the option called something like fit, just scan, full pixel or 1:1.
Blurry text usually means the laptop is sending a resolution the TV doesn't like. In the display settings set the TV to its recommended resolution, typically 1920 by 1080 or 3840 by 2160.
Why not just cast it wirelessly
Wireless casting works for films, where a half-second delay doesn't matter. In a racing game or a buzzer quiz, it does: the car on the wall is behind the phone in someone's hand. Casting also shares the same Wi-Fi that forty guests' phones are using. A cable costs very little and removes both problems.
"Can't we just do it without the wire?"
"We can. Then we can watch it buffer."
Before the doorbell: the ten-minute test
Plug in the laptop's charger, never run a party on battery. Turn off sleep and screen saver for the evening. Switch on do-not-disturb so chat messages don't appear on the stage. Open the stage window on the TV, play a few seconds of music, scan the QR code with your own phone and play one round.
If you're new to this, do the test with the free 3-day demo, no card needed. After that the full version is a one-time license without a subscription; see pultevent.ru/en for the price.
