1920x1080@60
Front: 88/4
Sync: 44/5
HT 2200
VT: 1125

Are you saying that this is only for 60hz and not for 100, etc? (I have no way of knowing what's shown for 100/110/120 etc).

Most monitors use those timing parameters for 1920x1080 @ 60 Hz, including the ASUS VG248QE. Strobelight also uses those timing parameters for 60 Hz. Most 120 Hz monitors use CVT-RB for 120/110/100 Hz. You can see what the BenQ defines in the extension block by running reset-all.exe and restarting, and then use GetEDID or MonInfo to save the full EDID to a file that you can import into CRU.

Over DISPLAYPORT:
If I change the 1125 VT to 1155 VT, the monitor just shuts off.
Over DVI, it doesn't.

But if I change the timings to CVT-RB so it has the 2080 HT, then it activates lightboost mode double strobed.

I'm pretty sure LightBoost is supposed to use the CVT-RB 2080 HT, not the CEA 2200 HT.
