LightBoost, G-SYNC, Turbo240: 120Hz Strobe Backlight LCDs / No Motion Blur! - Page 48

post #471 of 2929
Well the colours are well known to be quite awful on the XL2420T so I think as you mentioned it is using better colour defaults. It wasn't something I expected but it was a drastic difference. I have been using this monitor since june of last year so I have had plenty of time to get used to the colours on it and where they are lacking. Initially everything was quite dark but once I upped the contrast to 65 it worked perfect.

Yes to the Crysis 3 question. Single player I run at maxed everything because it looks awesome but in multiplayer I drop all the settings to their lowest so that I can get the 120 Hz advantage I paid for with my monitor. I limit the FPS via precision-x to producing no more than the 120 frames my monitor is capable of displaying. I ran into an odd bug though while playing. I noticed that my FPS was halved down to 60 FPS and once I enabled and then disabled 3Dvision it returned back to 120 Hz. I only noticed it once and will keep an eye out but thought I would mention it. This shouldn't impact my FPS at all, correct? I don't have any source engine games but with running crysis 3 at 120+ FPS would it make a difference if I tried one or not? I have steam with a copy of CS that I haven't touched in years and could give it a go if you think it may shed light on soemthing.

I was able to get around 21 and some of 22. Anything more and this big ole head wouldn't turn quick enough.

Yeah mark but what about the 144Hz LCDs in particular at speed of 21, would it be possible to read? Would you say that 16 is the max non LB for u as well?

after I enable LB mode and rsed my comp it goes back to non LB :l any idea?

*fixed it*

apparently the new file that should enable switching between 144Hz non LB and 120Hz LB didnt make LB "stick" for me, while the old file did

I can't read much past 7 or 8when non lightboost 120/144hz. But 30 easily on lightboost.

Holy S! For real? Thats incredible and you must personally be sensitive to blur. Interesting how big of an impact it can have.

I can't read past 8 either with LB off.

It does have a huge impact if you try to compare scrolling text/pixperan readiblity with any 120-144Hz screen and 120Hz LB, I'm able to read at 30 clearly with LB but its hard to write it down perfectly. biggrin.gif

I can also personally confirm PixPerAn 30 too. CallSignVega has also confirmed this as well. It's almost too fast to read; you do need to turn your head while the text moves. Here are the motion comparisions of different modes on the SAME display:

PixPerAn Tests on BENQ XL2411T and ASUS VG278H

baseline - 60 Hz mode (16.7ms frame samples)
50% less motion blur (2x clearer) - 120 Hz mode (8.33ms frame samples)
60% less motion blur (2.4x clearer) - 144 Hz mode (6.94ms frame samples)
85% less motion blur (7x clearer) - 120 Hz with LightBoost at 100% (2.4ms strobe flashes)
92% less motion blur (12x clearer) - 120 Hz with LightBoost at 10% (1.4ms strobe flashes)

Instead of a frame displayed for 16.7 milliseconds continuously on a normal 60 Hz LCD, you've got a 1.4 millisecond strobe flash of the frame. This results in 12x less motion blur. This makes motion look as clear as CRT even for the most sensitive people, since phosphor decay is commonly 1 to 2 milliseconds.

The LightBoost HOWTO has been updated with some new tips:
Quote:
TIP: Improving Convenience, Stability & Eliminating “Control+T”
First, verify LightBoost is working by verifying for reduced motion blur, and Step 4 was already followed. Next, you can make LightBoost “stick” by going to nVidia Control Panel and disabling the “Enable Stereoscopic 3D” checkbox (see Step 8 above). If the screen did not flicker when doing this, LightBoost is still enabled even after disabling 3D!
- Games launch in 2D without needing Control+T
- Driver stability is improved in this mode, less freezing occurs.
- VSYNC OFF now works much more reliably, reducing input lag.
(Note: Some games may automatically switch resolutions; make sure it stays at 120 Hz)

TIP: Turning Off The LightBoost Hack Without Uninstalling:
To turn off LightBoost:
1. Turn off the “Enable Stereoscopic 3D” checkbox in nVidia Control Panel
2. Switch to 60 Hz mode, then switch back to 120 Hz (or 144 Hz).
You can use a system tray utility such as MultiRes to do this more quickly.
The HOWTO now has the new INF file that supports the non-strobe 144 Hz mode (no LightBoost):
http://www.blurbusters.com/files/LightBoost-Monitor-EDID-override.inf
This allows users to more easily turn on/off LightBoost by switching to 60 Hz then back to 120 Hz or 144 Hz, without needing to uninstall the INF file.
