R4 M17x suspect lightboost problem

Hi,

I have an R4 m17x with 675m and the SEC5044 screen. If I set my screen as dim as it will go with FN+F5, and turn on a 3D movie or game, the brightness does not increase in any way. If I raise brightness to full and play something in 3D, the brightness drops back down to the dimmest setting. Lightboost is definitely not working. I've seen other screens and it was impressive. My screen looks like 3D Vision Version 1. Dim......

I do not have a lightboost setting on my NVIDIA control panel? Shouldn't there be one? I think I have the wrong drivers, I've tried both what Alienware supplies, as well as Beta drivers, nothing has changed, still dim in 3D mode.

Any thoughts?

 

not quite sure if i understood your problem correctly, but you can´t "see" lightboost with your bare eyes.

its only "visible" when using the 3D-glasses, than you will notice a difference in brightness compared to 3DVision v1.

 

Is your 'alienhead' boot screen dark as well? I have a similar problem with my R4. In windows brightness has to be up to full but in-game it goes dark and I have to hope the game has a brightness setting. This is much darker than my R3 (without lightboost)
Think there is a problem with the panel, I have a call into dell about it - three times now and still trying to talk to someone

Promised a call within the hour - we'll see but I'll update if I get a response...

Edit: Got the call (finally) and they said my display is probably faulty so they are sending a tech with replacement. Let's see if that sorts it.

 

I may be calling mine in here soon. It's simply too dim in 3D mode to use 3D. If I could override the panel brightness, I'd be fine, but once 3D is on, it locks in a dim setting.

Anyone with working lightboost, can you check your NVIDIA contol panel 3D settings and tell me if there is a lightboost setting?

I wish the NVIDIA forums were working. Using Google cache, I found this which is what leads me to believe there should be a setting for Lightboost that I am missing...

Jan 6, 2012 – My personal settings for my VG278H is contrast at 50%, Lightboost at 100%, and Trace at 100. This post has been edited by Arioch: 15 January ...

 

I don't have the setting either, but my panel is quite easily viewable. Just read this that might solve you're problem though : http://forum.notebookreview.com/showthread.php?p=8717179

States there is a new bios coming out this week with some 3d fixes

Allright. I'm a little more satisfied with the display now. Here's what I did...

NVIDIA Control Panel changes.
Adjust desktop color settings :
Use NVIDIA settings
Brightness 75
Contrast 100
Gamma 1.0

Digital vibrance 75

I think I saw lightboost come on once or twice. It was barely noticeable. I do think NVIDIA has driver control over the display backlight, and if they'd leave that alone, the image could be made much brighter without hurting your eyes. Maybe the panels can't handle it. Just wish there was a way to stop the panel from being taken control of.

 

Note: The settings I posted work well for me for 3D videos, but are terrible for desktop.

 

hi ppiddy01, did you ever get this resolved by dell? i'm having the same issue.
mine looks just like the vision 1 image no the left on this site: Articles : Twice As Bright: NVIDIA Announces 3D Vision 2 | GeForce

 

I know this is old, but did this resolve it?

 

Not really. Dell replaced the panel but it was only slightly better. I figured it was just the panel model since dell released a bios recently and I saw that the POST screen progress bar had been made brighter. I think it was a common call-in so they did that

 

thanks for the quick reply. and that is unfortunate, so essentially we just have 3d Vision 1.0 on something should have been 2.0. I can't believe there isn't a monitor driver out there for this thing cause how else would the nvidia drivers know that the SEC5044 supports lightboost.

 

You're welcome

I think it is working (lightboost) only because as they (NV) state, I can see my keyboard better with the glasses on than with my R3 where it became almost invisible, but have no idea what it is doing or how it works.

I'm guessing it's that a lightboost display is just darker overall when not in 3D vision mode - overcome with in-game gamma setting.

 

I have the same problem too. Whenever I play games in 3D vision mode, the screen goes to the dimmest setting possible. I have the 3D vision glasses 1 and 2 and to my surprise, they both are the same. I suspect it's my screen. I have the M17X R4 SEC5044 (lightboost capable) but I just don't feel that its working? help?

 

I gave up and just set the gamma or brightness in-game.

I had dell replace my panel as I was sure it was faulty since the BIOS screens are dim. No change.

All they did recently is change the brightness on the progress bar so it does not appear dim, in the latest bios update.

 

First post since I've been away for a while. You guys are worrying too much about your screen dimming when 3D is on. That's the way lightboost works. Lightboost does not mean that your screen is brighter when in 3D, it is the technology that allows your viewing through the glasses brighter allowing you the possibility of using 3D even with the lights on or the windows open. The screen dims because it is calculating the amount of light to let through each eye. I have both generation glasses and have compared with screens with an R3 without lightboost. The R3 display is brighter overall and also when displaying 3D, the R4 display is similar brightness in normal operation and much dimmer in 3D BUT when you put on the glasses, the R3 display is really dim and flickery whereas the R4 display is much brighter through the glasses even though without it looks dim compared to the R3. It's a backlighting technique, not a brightness of the LCD.

 

but seriously, I can barely see what im playing even with all the lights off. Same goes with my brother's R3. They are the same in brightness when in 3D even with both glasses switched. Is it meant to be like this?
