Benchmark board
This page collects the real TargetBridge presets already documented by the project, from 1440p 60 up to 5K 48 HEVC. Where hard comparison data is still missing, the page says so clearly instead of pretending the benchmark set is more complete than it really is.
Current board
The rows below separate documented presets from numbers that still need a same-hardware comparison across TargetBridge, AirPlay and Luna Display. That keeps the page useful now without dressing up missing data as if it were already settled.
| Metric | TargetBridge | AirPlay | Luna Display | Source note |
|---|---|---|---|---|
| Highest documented preset | 5K · 5120 x 2880 @ 48 · HEVC | No comparable 5K-first preset is documented here. | Astropad advertises full 5K iMac support. | This row shows what is publicly documented today, not the result of a like-for-like lab test. |
| Sharp-text preset | Crisp · 3840 x 2160 @ 48 · HEVC | No similar text-focused preset is documented here. | No comparable preset table is published here. | This is the preset most people will care about for text, coding and general desktop work. |
| Motion preset | Smooth+ · 3200 x 1800 @ 60 | No same-hardware 60 fps comparison is published here. | No same-hardware 60 fps comparison is published here. | This is the row to cite when talking about cursor feel, scrolling and window movement. |
| Lower-latency preset | Smooth · 2560 x 1440 @ 60 | No comparable low-latency preset is documented here. | No comparable low-latency preset is documented here. | Think of this as the safest public baseline before moving to higher resolutions. |
| Average latency | The repo does not publish a same-hardware latency figure in milliseconds yet. | No same-hardware latency figure is published here. | No same-hardware latency figure is published here. | Milliseconds only become useful when sender, receiver, cabling and macOS versions all match. |
| CPU / GPU load | The repo does not yet include a public sender/receiver load chart. | No comparable load chart is published here. | No comparable load chart is published here. | When this data is published, sender and receiver load should stay separate so the thermal cost is easy to read. |
Public reports
These are not official lab benchmarks. They are public GitHub reports that add concrete context about 5K HEVC behavior and Network Link limits on real hardware.
GitHub issue #11
A public GitHub issue reports 5120 x 2880 @ 48 HEVC running between 2 and 16 sender FPS on a MacBook Pro M3 Pro to 2020 Intel iMac pair, with severe flicker that made the setup unusable on that hardware combination.
Read source reportGitHub issue #47
A public GitHub issue reports 5K starting over both WiFi-to-WiFi and WiFi-to-LAN paths. The same report says the local network was not fast enough for good speed, which supports the project recommendation to prefer Thunderbolt Bridge first.
Read source reportMethodology
Every new benchmark drop should read like a reproducible experiment. That keeps the numbers comparable and makes public reports more useful for everyone evaluating the project.

Include exact sender and receiver models, macOS versions, cable or adapter path, and raw observations. GitHub Discussions and Issues are the right place to share that evidence before it gets promoted on this page.
