LightBoost, G-SYNC, Turbo240: 120Hz Strobe Backlight LCDs / No Motion Blur! - Page 96

post #951 of 2929
Still not able to get LB working properly (and I have a GTX 670 now). I can get the 3d to work properly, but I'm not able to access LB in the OSD. The odd thing is, using the CRU method I don't have the ability to select "Asus 120hz" under stereoscopic 3d, I can only use the 3d Vision Discover. However it does work fine (caveat being LB isn't accessible), the only way I can get the checkbox to select Asus 120hz is if I install another monitor inf. Changing the product ID from ACI24E1 to ACI27F8 doesn't allow me to enable it, even after a full reboot. Problem is, as soon as I use the monitor inf, and reset everything within CRU (and use Asus 120hz stereoscopic enabled), as soon as I boot a game the screen goes scrambled. I can make out the text that the 3d driver is working, but not much else. I've exhausted pretty much every option at this point, couldn't tell you how many times I've reinstalled clean drivers, and did system restores to test out different options.

Does anyone have any suggestions?

Which monitor are you using? Have you also tried doing the ToastyX method instead of the EDID override method too as well? (Installing the lightboost.bin file). Do you have any secondary monitors? Are you using a dual-link DVI cable? (regular 120Hz should look correct and not low-rez)

1. Asus VG248QE
2. Yes, by CRU I mean the ToastyX method of installing Lightboost.bin
3. No secondary monitors.
4. Dual Link DVI cable I received with it, normal 1080p @ 120hz looks perfect.

I am now wondering if you have defective DDC line (DDC is serial communications protocol that your monitor uses for host communications, LightBoost requires this to activate: It's confirmed that LightBoost does not activate if the DDC wire in your DVI cable is defective or disconnected in the DVI cable -- it becomes impossible to activate LightBoost if you have no DDC)

Can you download SoftMCCS and install / run it?
-- If your DDC is working, you'll see data about your monitor. (Your problem is caused by something else)
-- If your DDC is malfunctioning, you'll see no monitors detected. (This may mean you'll need to return your monitor, but first try testing using a different DVI cable, one pin (the DDC pin) may be malfunctioning)

DDC is working using the software you recommended. "DDC/CI.............................. Supported".

Hmmm, OK, it's not a dead DDC line. I'm starting to get stumped on this.

When the screen is scrambled, does it say that 3D Mode is enabled in the monitor?
What happens if you try to hit Control+T while the screen is scrambled?
Does things fix themselves? If so, try disabling the 3D stereoscopic checkbox in Control Panel, and see if 3D Mode stays enabled in the monitor. Ideally you want to disable 3D mode on the computer side, but keep 3D mode enabled on the monitor side -- that's the Lightboost state for 2D operation.

When the screen is scrambled, the OSD is illegible. Can't make out anything, all I can do is confirm that it pops up, but it's a mess. Control + T won't do anything, and things do not fix themselves. I have to reboot into safe mode and system restore from a restore point before I made changes. Booting into low resolution video mode (640 x 480) won't even fix it.

Does Lightboost require more GPU power to run than standard 120 Hz? How far would I need to upgrade my Video Cards in order to run Lightboost in Surround as actually make use of it? I know Vega is running Lightboost in Surround, but not all of us can afford Quad-SLI Titans.

I'm hoping SLI 780s that are being released next week would be enough. But if someone tells me that you need at least Tri-SLI Titans or SLI 690s then... doh.gif

P.S.

If you change your refresh rate for your monitors to 110 Hz when using the Lightboost Hack does your GPU downclock properly? Is it even safe to have your GPU downclock with Lightboost?

You GPU isn't doing anything with lightboost. It's a monitor thing. No more power or anything smile.gif

Could you explain the circumstances the one time you got it working?
