BenQ XL2411Z: 3D Vision and Crosstalk

[Salk]

Hello!

I have just ordered a BenQ XL2411Z monitor and it should arrive next week and replace my current LG W2363D which I am using to play a few older games using 3D Vision glasses (first generation).

The reason why I decided to change monitor was that I read that the Blur Reduction should help reducing (eliminating?) crosstalking while playing stereoscopic games. The situation with my current monitor was, in my opinion, bad.

I tried documenting myself before proceeding with my purchase but I would like to ask a few questions:

1) I own the first generation of 3D Vision glasses. Will there be still a significant improvement when it comes to reduced crosstalking or is it necessary to buy the V2 glasses?

2) I read about the unofficial V4 firmware. I do not know whether or not my monitor will have V2 presinstalled but I would assume it has. From what I read around here, the flashing does not seem to be very user friendly. Would there be any real benefit in regards to the XL2411Z model?

3) Again about Crosstalk in 3D: does any of you have simple recommendations to further reduce the problem? I read that the XL2411Z has poor contrast ratio (600:1). Does this have any bearing?

4) I have read a review of this monitor here (http://www.digitalversus.com/lcd-monito ... /test.html) - the reviewer speaks of bad factory settings and suggests to use their profile (http://www.digitalversus.com/lcd-monito ... ap437.html). Has anyone tried them?

Thank you very much for your attention!

Cheers!

1) The glasses generation doesn't matter regarding to crosstalk. The difference is about the glass size, battery duration and shape of the glasses. So don't worry about this.

2) For 3D Vision, no difference. Zero. For blur reduction (no 3D) it makes a difference (it looks better) in inverse ghosting when toggling AMA to High.

3) The lower the contrast, the less crosstalk you'll get in general. Also, let your monitor warm up about half an hour before playing. 37 contrast is the default, and it's a good number. There is nothing else you can do. TN isn't fast enough to get 0 crosstalk. And you can't configure the overdrive in 3D, at least with this monitor.

4) No. I made my own ICC profile, adjusting gamma with QuickGamma until it was nearly perfect. Again, let it warm up. It will be more washed out until that.

Thank you very much for your advice.

A curiosity, if TN is not a fast enough to remove 3D Crosstalk altogether, what kind of panel would instead do the trick?

Thanks!

CRT or OLED.
I had 3d glasses back on a Voodoo2 / Geforce and a CRT. ZERO crosstalk back then. ZERO.

And some projectors that are compatible with 3D Vision. They have zero crosstalk, but they are limited to 720p because of the artificial limitation in Nvidia 3DTV Play.

Thanks for your help, guys.

I did try the same game I had serious 3D Crosstalk issues with and the difference with this monitor is astounding. I am very satisfied. It seems it automatically enables nVidia Lightboost but I don't think that's what makes it so much better (I turned it off and the 3D Crosstalk amount was the same).

I take the opportunity to ask you a couple questions more:

1) I have this setting called AMA that can either be: Off, High or Premium. It's currently set on High. Is it alright?

2) I applied the Vertical Total 1350 Trick and I must say the immediate improvement in brightness makes it a great solution but is it only limited to 1080p?

Thanks again!

Sorry for answering two days late. I wasn't checking the forums.

I am very satisfied. It seems it automatically enables nVidia Lightboost but I don't think that's what makes it so much better (I turned it off and the 3D Crosstalk amount was the same).

Yes, it's what makes it better (because of the strobing. You also get low motion blur as a bonus). And it's forced once you are playing something in 3D.

1) I have this setting called AMA that can either be: Off, High or Premium. It's currently set on High. Is it alright?

Once you are in Lightboost mode, that doesn't matter. But yes, High is the recommended setting. Off has lots of ghosting and Premium has excessive inverse ghosting. In this regard, you will see that Lightboost is superior to blur reduction + AMA High.

By the way, AMA High can look better if you toggle it off and on, after every time you turn on the monitor or change refresh rate or enable-disable Lightboost.

2) I applied the Vertical Total 1350 Trick and I must say the immediate improvement in brightness makes it a great solution but is it only limited to 1080p?

As this is a 3D Vision thread, I'll start saying that the Vertical Total trick doesn't affect Lightboost or 3D Vision. Only non Lightboost modes.

It isn't limited to 1080p. You must make a custom resolution for every combination of resolution and refresh rate you want it. You have 32 slots in the Nvidia Control Panel. I know because I tried to make more and older custom resolutions were silently deleted.

And you're welcome!

Thanks a lot, masterotaku!

I was asking whether or not it was limited to 1080p simply because I thought the value chosen (1350) was only correct for that specific resolution. I guess I should use the same value even if I create a custom 720p resolution then?

Cheers!

You can't use VT tweaks with custom resolutions lower than native.
If you want a low res (why? just why??), use GPU scaling if you create the resolution. Then it will use the resolution data for 1920x1080 and the video card will downscale it.

Have you tried using 1440x1080 (this fits vertically in the vertical resolution screen size) with Lightboost? (100hz = VT 1138, 110hz=VT 1143, 120hz=VT 1149?)
If you do this as a display scaled (instead of GPU scaled) EDID override, your monitor enters 3D mode with rainbow pixel lines on the entire right half of the screen, with the regular display centered left at 1440x1080. So no, you can't use 3D display scaled at lower resolution.

It works if you GPU scale to lower resolution (then all you need to do is create something fast like 1280x720@60hz, then GPU scale 1920x1080@120hz to 1280x720@120hz).
