2. You explained that there's no visual effect between different blanking settings. But the blanking for LCD is the waiting time. If I have a longer blanking, doesn't that mean my screen need more time to response, so that I'd have a lower refresh rate?

1. That depends. Monitors usually use the CVT-RB standard, which is what "LCD standard" uses except for TV resolutions. One exception is 1920x1080 @ 144 Hz monitors, which use non-standard timing parameters to fit within HDMI and dual-link DVI bandwidth. "LCD native" is non-standard, but it happens to match the CEA/CTA standard for 1920x1080 @ 120 Hz, which is what TVs use. The next version of CRU will have separate timing options for TVs.

2. No, the pixel clock is also increased, so the visible (non-blanking) part actually refreshes slightly faster with a longer blanking. The refresh rate remains the same.

Dear ToastyX, thanks for your explanation.

I am using a new monitor right now, and I will observe if the problem would still exist.
