DisplayPort Switchbox Hack to Enable LightBoost

stupdude2 · Post by **stupdude2** » 05 Nov 2021, 08:34

I have a laptop connected from USB-C to DisplayPort to an Asus VG248QE through a DP switch. The switch swaps the monitor between my home PC with Strobelight configured and the laptop which doesn't support it. Rarely and miraculously, when I click the DP switch between PC and laptop, the strobing continues and I get no motion blur using the laptop! Has anyone else experience this? Anyone know a way to more consistently keep the strobing when swapping to the laptop?

Thank you.

I solved this by adding custom resolutions following this tutorial and it works.

That's pretty neat. Bait-and-switch technique to get LightBoost working on non-computer sources.

LightBoost has a DRM handshake with a proprietary NVIDIA code.

Usually ToastyX strobelight can execute this hack without needing bait-and-switch (but can have difficulty on Intel GPUs), but it's interesting to know that the bait-and-switch technique also works!

Dunno if this will work on ULMB though, as the handshake for ULMB is much more rigorous/locked to NVIDIA cards.
