TightProjector — sometimes all that’s needed is to push the screen out, nothing more
No HDMI splitters. No cables taped to the floor. No laggy screen shares over Zoom. Just one machine, showing its screen, and others on the network quietly picking it up. That’s what TightProjector does. No fanfare, no cloud, no installs if not needed.
The sender runs, grabs the screen, and starts pushing it out — multicast or unicast, depending on what the network allows. The receivers? Just launch the tiny viewer, enter an address, and the screen shows up. It’s not real-time down to the pixel, but for most classrooms, meetings, or shared monitoring setups, it’s good enough — and dead simple.
What It Offers (without getting in the way)
| Functionality | Why It Ends Up Being Useful |
| LAN-based broadcasting | Doesn’t need the internet — works entirely within the local network |
| Multicast or direct IP | Can handle simple setups or be tuned for specific viewer groups |
| Receiver is lightweight | No installs, no config — run and connect |
| Sender is straightforward | Choose screen, pick mode, press Start — no wizard, no menus full of jargon |
| Stays out of the way | Once started, just keeps streaming until stopped |
| Handles unstable networks | Drops a frame? No problem. Recovers smoothly without hanging |
Where It Gets Used (and why)
– In school labs, where teachers share one desktop to dozens of student machines — over LAN only
– In corporate training rooms with a local subnet, no projector, and not enough budget for AV
– In factories or shop floors — screen from control station mirrored to wall terminals
– In temporary spaces where Wi-Fi is unstable and physical connections aren’t possible
– Anywhere that needs passive viewing, not interaction — just “see what’s on the instructor’s screen”
It Doesn’t Need Much
| Requirement | Notes |
| OS | Windows (Sender and Receiver both); XP-era compatibility still holds |
| Network | Local network; multicast-capable preferred, but unicast works |
| Setup time | Less than five minutes, especially for portable version |
| Install | Not required — standalone executables available |
| Licensing | Free edition handles the core; Pro adds scheduling and multi-source options |
Quick How-To
Step 1 — Get both apps from https://www.tightprojector.com
Grab Sender and Receiver separately. Either install or just unzip and run.
Step 2 — Start the sender
Open the app, pick full screen or region, choose multicast or IP mode, and press “Start”.
Step 3 — Open receiver(s)
Run TightProjectorReceiver.exe, enter sender’s IP or group address, and hit connect.
Step 4 — Watch
Whatever is on the sender’s screen appears on the receiver. No mouse lag, no video stream — just compressed stills, refreshed constantly.
Optional tweaks — Adjust image quality or update interval to fit bandwidth or screen clarity needs.
And That’s About It
TightProjector isn’t flashy. It doesn’t try to solve everything. But in the right setting — where things need to “just work” without complexity — it does the job better than most.
It’s the kind of tool that’s forgotten until needed… and then, once tried, usually stays on the flash drive for good.
