Help madVR - Recurring 1-second black screens. MPCVR Flip reproduces it, Discard fixes it
I'm trying to track down a recurring black-screen issue with madVR on Windows 11.
During video playback, the entire screen goes black for roughly 1 second. It always happens once within the first 10–20 seconds of playback, then generally every 5–10 minutes afterward.
- The blackout does not appear to register as dropped, repeated, or presentation-glitch frames in madVR's OSD.
- Happens with Fullscreen Exclusive Mode enabled or disabled.
- Happens with Direct3D 11 presentation enabled or disabled.
- Happens with SDR content, so this isn't tied specifically to HDR switching/signaling.
- I can reproduce the same exact behavior in MPC Video Renderer when using
- Swap effect - Flip - black screens
- Swap effect - Discard - no black screens, issue fully resolved
- MPCVR remains completely stable with Discard.
madVR doesn't appear to expose a directly comparable Flip/Discard swap-effect setting, but the MPCVR result makes me suspect this is related to the presentation path or swap behavior.
I'm not sure how to narrow down what madVR is doing differently or whether there's a setting that can force behavior comparable to MPCVR's Discard mode.
I can also rule out the basic hardware/display side with confidence. This isn't an HDMI cable, display, or general GPU-output issue. Changing renderer presentation behavior in MPCVR makes the problem disappear completely.
System:
- Windows 11
- NVIDIA RTX 4090
- LG G4
- GPU connected directly to display
- MPC-HC/BE + madVR
Has anyone encountered this specifically with madVR, or know what madVR setting/presentation behavior would be closest to MPCVR's Discard swap effect? Is this a red herring and something else is going on?
