G-Sync and ULMB at the same time is in fact possible!

Welp, BRB gotta go buy a 3D Vision kit.

Welp, BRB gotta go buy a 3D Vision kit.

Not so fast, if you don't want to have one (I love 3D, though). If you buy one, make sure it's a 3D Vision 2 kit (you are going to try 3D, so better with the good glasses :p).

I would wait until other people from the Geforce forums (I know some that have the same monitor as me) confirm if it works for them.

If anyone is bored, can you see if you can force 3d vision 2 as an option in the NVCP by spoofing the driver?

Use toastyx custom resolution utility to change the "product ID" of your monitor to ACI27F8
Click edit at the top and click product ID and change it to ACI27F8.

Then reboot and see if set up stereoscopic 3D appears in the NVCP.
if it does, there may be a way to force Lightboost to work without needing glasses. On the old original Lightboost monitors, all you needed was an Nvidia video card and the INF override and you needed to know the proper Vertical Total values.

Dude, that's INSANE!

I was testing it out on my XL2420G switching between G-Sync/ULMB modes and games on 2389x1344 and i couldn't get it to stick. I don't have 3D Vision glasses and i never installed the '3D Vision' app in the driver, Do you need 3D glasses?

I was also assuming it's 2389x1344 at 120hz with default timing done in Nvidia's control panel right?

I would LOVE to get this to work on my monitor!

> Nvidia will officially add this mode in the drivers.

you have the power to do that?

Edit: I saw you changed your youtube descriptions. Will try.

You will need a lower custom resolution, because youre not using a 1440p panel.

Remember that you aren't using the Benq Mstar scalar here either. You're using the Gsync module when you're in gsync mode.
You can't go higher than native resolution on your monitor directly, which is 1920x1080.
The 2389x1344 resolution works because his monitor is 2560x1440.

I also don't think this resolution will work via an EDID override. ToastyX said that the Nvidia control panel creates GPU scaled resolutions, not EDID overrides, which is why resolutions created and shown in the Nvidia control panel do not appear in ToastyX CRU. You can try it.

If the "active" pixels are changed, then it's a "real" resolution, even though it's still not an edid override. If the active pixels are still 1920x1080 or 2560x1440, then it's a GPU scaled resolution. We found out about this when someone was making the XL2411Z run at 180hz refresh rate like this, when the monitor was being sent an actual 144hz signal, but the driver was set to 180 hz. Needless to say it wasn't pretty. (the benq firmware prevents any refresh rates higher than 145hz from working).

For your monitor, you would need a lower custom resolution lower than 1920x1080 if you're trying to do this trick on a 1080p panel. Remember that.

Also for 1920x1080 monitors, the 3d vision 2 Lightboost refresh rates are:

100hz: VT 1138
110hz: VT 1143
120hz: VT 1149

When trying to set up stereoscopic 3D on a 1080p monitor, activating one of these vertical totals by any custom resolution (change the active timings) will turn on Lightboost mode, if you did a hack or workaround to get the "Setup stereoscopic 3d" to appear in the NVCP.

So far, no one knows if the 1440p panels have equivalent vertical totals, but if we follow the pattern, the Lightboost VT is +5 higher than the "default" VT.
So if 2560x1440 @ 100hz had a default VT of 1510, then the lightboost VT would be VT 1515, IF it followed the 1080p monitor pattern. *IF*. And 120hz would be VT 1530 (1525 + 5).

Try this: http://helixmod.blogspot.com.es/2015/10 ... n.html?m=1

You can tell the drivers that you have passed the 3D initial setup.

I've been trying to do this for a few hours now... I'm so tired. The best i've been able to do is switch from Stero 3D to G-Sync with lightboost still on but when i start a game the screen just goes black...

If anyone is bored, can you see if you can force 3d vision 2 as an option in the NVCP by spoofing the driver?

Yep, it maybe kinda works. I got it too show me stuff i didn't have previously but i'm not too sure how this helps.

Heres a screenshot of the resolution screen with the 'name' of the monitor 'Ancore communic...' but it only has 60hz values

And a shot of the 3D vision ready saying "Asus 120hz 3D LCD"

Here is what it's like before i did the 'glitch'
http://i.imgur.com/tKLlVCl.png

It's super weird though. I was creating a custom 120hz res and my screen went black, after 10sec or so my screen turned back on with Lightboost timings (not what i put in) so i didn't click accept, but it reverted back to 1080p 120hz lightboost... Suddenly out of no where my monitor was set to 120hz and i didn't even accept it.

1- Enable 3D Vision and make sure Lightboost (not ULMB) is enabled in the desktop, using the "always" option

What's the always option? I would love if you did a video of you enabling the glitch state.

2- Create a 120Hz custom resolution. I have tried 2389x1344 and 2528x1422.

Does it work at only those two specific res? Does 1080p/1440p work? Do you switch to that custom res after you create it?

4- Now that custom resolution is locked into this G-Sync + ULMB mode (the monitor OSD will say "ULMB 120Hz")

How are you making those games and demos run at your custom res? it doesn't look like you have lightboost/ulmb enabled in the desktop.

I'm going to keep trying but i'm still not 100% sure if i'm even close, i would love to see a video

Edit: Also are you using CRU or NVCP?

Edit: I got 3D vision running in proper stereo 3D but when i do the 3D demo or play CS:S my computer slows to a craw <3fps~.

@lexlazootin

I'm going to record a video today and upload it tomorrow showing the process.

The "always" option (the top one in the selector, IIRC) is the one that applies 3D at all times, instead of only when a program is executing.

The monitor OSD will say "Normal mode" instead of ULMB but it will be strobing. Sometimes you have to switch and apply these two settings to make the "always" setting work in the desktop.

Make sure your default monitor state is ULMB instead of non strobed fixed refresh rate.

After you are in "Normal mode", create the custom resolution (everything worked in my case, except for reserved resolutions like 1920x1440 that already exist), then fully enable g-sync.

Then try to use a game at that resolution.

[masterotaku]

By the way, when you create a custom resolution, DON'T touch the timings. Just use whatever the monitor wants to use. It won't give you a black screen.

My monitor wasn't strobing at desktop in the pendulum video because I had gsync enabled, at 2560x1440. If I switch to one of those custom resolutions, they use ULMB at desktop (waiting to be converted to G-Sync+ULMB as soon as a game runs).

I was testing with the spoofed product ID 'ACI27F8' because it let me select 3D vision in the driver and turn on lightboost without hacking it with timings. Then i realized that the monitor i was spoofing didn't even support G-Sync... I could get lightboost working and select G-Sync at the same time but G-Sync wouldn't ever actually turn on.

Can you tell me the Product ID of the dell? i don't know why, but it might be worth testing.

Edit: Every time i get lightboost and G-Sync on at the same time default id, my screen goes black... i got a feeling it just doesn't work on my monitor :*(
