Stream your PC games to an LG TV
Punktfunk has a native app for LG webOS TVs, built by dyptan-io. It streams up to 4K120 with HDR through the TV's own video hardware.
Stream to a friend over the internet without opening your network
A friend wants to join tonight but isn't on your Wi-Fi. Let them reach one Punktfunk host, and nothing else on your network.
Multi-seat game streaming on Linux: everyone gets their own game
A Linux host can give each streaming device its own game: its own screen, input, sound and mic, and optionally its own Steam.
On Windows, Punktfunk encodes inside the display driver
Punktfunk's Windows display driver encodes each frame as Windows composes it, and the host only sends the result. On an RTX 4090 at 4K120 that means 4–8 ms end to end.
The BC-250 has no video encoder. It can still stream your games.
The BC-250's video encoder doesn't work, so most streaming hosts can't use it. Punktfunk's PyroWave codec encodes on the GPU's shader cores instead, over a cable.
PIN pairing that can't be brute-forced: SPAKE2 for game streaming
A 4-digit PIN has only 10,000 values. With SPAKE2 pairing, an attacker gets one online guess per PIN and nothing to crack offline.
Low-latency streaming when the game maxes out your GPU
A game at 100 % GPU makes the stream wait its turn. Punktfunk asks for real-time GPU priority by default on Windows and Linux. Where, and what it costs.
Why Punktfunk ships its own virtual display driver
A headless streaming PC needs a virtual display. Punktfunk's Windows driver matches your client's mode and HDR, shows the lock screen, and encodes the frames itself.
IDD-push: Windows capture without Desktop Duplication or WGC
Punktfunk doesn't capture the Windows desktop with Desktop Duplication or WGC. Its own display driver receives each frame from Windows and encodes it there.
DirectX HDR works, Vulkan HDR doesn't: confirm the cause
Vulkan games read HDR from the GPU driver, which hides it on a virtual display. Three checks show whether that is your problem.
A Vulkan layer that brings HDR back to virtual displays
NVIDIA and AMD Vulkan drivers accept an HDR swapchain on a virtual display but don't list the format. A small implicit layer adds the missing entries.
Vulkan games say “HDR not supported” on a virtual display: the fix
NVIDIA and AMD Vulkan drivers hide HDR from games on a virtual display. Punktfunk's Windows installer ships a Vulkan layer that shows it to them again.
Crisp text over the stream with 4:4:4 chroma
Small text smears because most streams send a quarter of the colour detail. Where Punktfunk sends full 4:4:4 chroma, and how to turn it on.
Controllers over the stream: gyro, triggers, rumble and haptics
Which virtual pad a Punktfunk host creates, what each client forwards, and what to pick for gyro, adaptive triggers and DualSense haptics.
Streamed audio that stays clean, in sync and in surround
How Punktfunk carries game sound, surround and your microphone, keeps audio in step with the picture, and what to check when it crackles.
Streaming from a multi-monitor PC without picking a screen
Punktfunk gives each device its own virtual screen instead of capturing one of your monitors, and lets you decide what your monitors do meanwhile.
The best self-hosted game streaming setups in 2026
A fair roundup of self-hosted game streaming: Sunshine + Moonlight, Apollo, Parsec, Steam Remote Play and Punktfunk, with a pick for each setup.
Punktfunk vs Sunshine + Moonlight: where they differ
Sunshine + Moonlight is the open-source default for streaming your PC. Where Punktfunk differs, and where Sunshine + Moonlight is still the better pick.
Stream PC games to the Steam Deck without leaving Gaming Mode
The Punktfunk Decky plugin puts your hosts in the Quick Access Menu and on Steam's own Play button, so streaming stays in Gaming Mode.
Stream to ultrawide and 32:9 screens at their real resolution
Punktfunk builds the host's display at your client's exact size, so a 21:9 or 32:9 screen gets its own shape instead of black bars.
