Re: Blur reduction and 240Hz monitors

Thanks paul. So Strobe Duty is at 08. Strobe phase at 049. In the BBSU Crosstalk is set to the 6th notch, counting from left. I think that's good, right?

I'm at 120Hz 1080p using the VT1500 tweaks. AMA Low, Contrast=19 Brightness=100 I've just readjusted in the service menu. Strobe Duty=009Strobe Phase=040 Single strobe=onFalkentyne wrote:Strobe phase at 049? Are you using 100hz refresh rate with a vertical total tweak?
What are your exact settings?
Because WITHOUT a VT Tweak, the strobe phase should be only at 000 (more input lag but less crosstalk at the bottom) or 100 (less input lag but more crosstalk at the bottom).
With VT tweaks active, the backlight "Shut-off" point is strobe phase 048 at 125hz, strobe phase 050 at 120hz, and strobe phase 060 at 100hz. Your strobe duty + strobe phase should add up to the backlight shutoff point, so at 100hz + VT 1500 for example, strobe phase 052 + strobe duty 008=060, And at 120hz, strobe phase 042+Strobe duty 008=050. Check your settings.
Almost exactly the same settings as I'm using. I have strobe duty = 6 (I don't mind slightly less bright screen) and strobe phase = 0 (I don't mind 1 frame of input lag). You're pretty much using the optimal settings (as far as my limited experience goes).Sirslicey wrote:I'm at 120Hz 1080p using the VT1500 tweaks.

can this be achievable via a software something like toastyx strobelight app on a BenQ XL2540?Chief Blur Buster wrote: TN 240Hz LCDs can probably achieve super-clean look simply by doing this too for 120Hz and 144Hz strobing, too. Assuming the LCD scan is at the full speed (1/240sec) with a large idle period between refresh cycles. For an 8.3ms refresh cycle, 4ms of scan and 4ms of pause (blanking interval. One could even give the LCD 1ms GtG transition a full healthy 3ms to completely settle, before doing a 1ms strobe flash, before beginning the next refresh cycle. This would produce extremely clean refreshes.
Not the same protocol, but in theory, if the backlight controller could be hacked, it could be done. There will probably be color issues, but the ghosting could pretty much virtually disappear, depending on overdrive logic differences at 120Hz versus 240Hz.alex47 wrote:can this be achievable via a software something like toastyx strobelight app on a BenQ XL2540?
