Common Pixera errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact software is in Ask Roadie.
- Step-by-step fixGet the fix →
Display Sync timed out / Display Sync deadlock -- render engine crashes and Pixera drops out of fullscreen
Likely cause: The Nvidia driver can stop signalling that the buffer-to-output swap completed, deadlocking Pixera's render loop; OpenGL PrePresentWait plus triple buffering restores reliable frame exchange.
- Step-by-step fixGet the fix →
Local service is not available -- no output, screen not assignable on local machine, no preview, logs not generated, Pixera crashes on close
Likely cause: The RX render engine needs write access to ProgramData for logs, a live NIC to bind its local service port, and an intact install to launch -- any of the three missing throws this error.
- Step-by-step fixGet the fix →
Manager cannot discover a Client / machines not seeing each other on the network
Likely cause: Discovery is multicast bound to one NIC; a version mismatch, active firewall, wrong IP filter, or a managed switch that blocks multicast all break the Manager<->Client handshake.

No output and/or no preview -- black screen basic checklist
Likely cause: Works back from the output head to the media so you isolate whether a black output is an engine/discovery, mapping, or content problem.
- Step-by-step fixGet the fix →
Output stutters right after a timeline jump or seek
Likely cause: A jump gives the engine no lead time to decode/upload the destination frames unless they are already preloaded into RAM/GPU.
- Step-by-step fixGet the fix →
Output stutters/tears but the Dropped and Incomplete frame counters stay at zero
Likely cause: Portrait rotation silently breaks Nvidia hardware output sync, so frames tear without being counted as dropped because reliable counting only works when sync is actually applied.
- Step-by-step fixGet the fix →
Stuttering or jittery playback with frames dropping under load
Likely cause: Stutter is usually I/O- or decode-bound: slow drives, CPU-heavy long-GOP codecs, or no preload starve the GPU of ready frames.
- Step-by-step fixGet the fix →
Tearing or outputs not frame-synced across multiple heads (genlock/framelock)
Likely cause: Genlock aligns every GPU's scan-out to one reference clock so multi-output content does not tear; without a sync card the heads free-run at slightly different phases.
- Step-by-step fixGet the fix →
What codec plays best?
Likely cause: HAP and NotchLC are GPU-decoded intraframe codecs that scale to many concurrent streams; long-GOP H.26x taxes CPU/GPU and stutters as layer counts rise.

Windows installer fails with Error 2502 and 2503 when installing or updating PIXERA
Likely cause: The MSI extracts to C:\Windows\Temp; without write permission there the install aborts with 2502/2503.
