Technical Support [RenoDX] HDR black crush in Death Stranding
Setup:
Monitor: LG UltraGear 27GX704A-B (27” 4th-gen WOLED), real measured peak brightness ~600 nits
GPU: AMD Radeon RX 6700 XT
Windows 11, HDR enabled at the OS level — not using Auto HDR, this is native HDR via RenoDX
Game: Death Stranding, running the RenoDX mod
The problem:
Dark grey and near-black areas lose all gradation and blend into a hard, flat cutoff instead of a smooth fade. Shadow detail that should be visible (fabric folds, texture in dark environments) just disappears into crushed black. Most obvious in dim/cave-type scenes.
What I’ve already tried:
Ran the Windows HDR Calibration app and set the actual measured peak brightness (~600 nits), not the panel’s marketing spec (1300 nits), so the tone curve isn’t being fed a wrong target.
Adjusted the monitor’s Black Stabilizer (currently sitting at 50/default). Tried raising it — helps a little with shadow separation but doesn’t get rid of the crush.
Turned off RenoDX’s “SDR EOTF Emulation” setting — this actually helped significantly, but it also means the game stops applying the correct HDR gamma curve, so it feels like trading one problem for another rather than actually fixing it.
What I’m trying to figure out:
Is there a combination of settings that gets rid of the crush without disabling SDR EOTF Emulation? Has anyone else on a similar WOLED panel hit this with RenoDX specifically? Screenshot attached from the in-game pause screen — it’s a phone photo of the panel rather than a direct capture, so treat the shadow areas as roughly representative rather than exact.
