Hi folks,

Just wanted to get some good advice on this monitor,

I recently purchased one of these and overall I was very impressed, especialy with the 2d to 3d function.

Although there are a few problems that i found with this monitor, one of which was the oem bundled tridef 3d software. I currently use sli gtx 580's in my system, when i try to use the 3d ignition software to play a compatible game (Crysis 3 or Deadspace 2) I experience a split screen view, two identical images divided from the centre vertically.

Is this a faulty panel? or is this an issue with hardware or software?

I really like this monitor and it is a massive shame that it does not support 3d vision, and i do not know if its worth going for a completely different monitor that is 3d vision certified based on my graphics cards because its not certain that this monitor will be sli compatible which makes it kind of useless if it doesnt in the future.

There is only one 3d monitor that is similar to the Samsung that i know off and that is the Acer HN274H but i have the feeling after reading some reviews on this that the Acer will not have as good image or colour quality as the Samsung.
 
Here is how to play in 3D with the supplied drivers (on NV cards).

Launch the required game via the launcher program. When you get the 2 identical pictures on the screen you need to put the screen into side by side 3d mode manually via the touch sensitive buttons on the front. That'll turn it into a "blurry mess", at which point turn on and put on the glasses! That's the process for NV gfx card users. The screen does not automatically change to 3d mode for NV gfx cards. When you want to go back you also need to manually reset the screen and turn off the glasse to save the battery.

The lack of 3D vision is a pain, but i'll stick with it as TriDef SBS is OK and hopefully they will support the better frame sequential mode eventually. Plus otherwise the screen is EPIC. 120Hz is amazing and it looks great!:cool:
 
Hi there mate yeh i got the split screen view sorted thanks to you bud.

Do you get any crosstalk with yours? I get crosstalk coming from the left and right eye of the glasses, the only way to get rid of it completly is to turn the depth down to 1 in the 3d menu.

Is there anything that can be done about this?
 
Yeah i get some crosstalk. :(

It varies between game, and can be adjusted in settings, but not totally removed from what i have achieved.

Sometime its pretty dire, sometimes you have to really look for it.

IMO its partly down to the software, partly hardware. I can only suggest fiddling around with settings for each game. I think thus far 3D is a little "hit and miss". I guess this is because its still relatively new tech and not widely supported.

3D is occasionally GREAT tho.:cool:
 
I had exactly the same issues, I notice a little bit of blurryness in the side-by-side, and also believe that halves the resolution?

Interlaced mode I just couldn't get to show correctly :(.

I can use the built in 2d->3d, but that's never quite as good. The side-by-side is SO close just not quite there.

Any ideas how to fix the interlaced mode?
 
Got my S27A950 in today. It's an upgrade to a Dell 2405.
First impressions
- looks great on the desk, unfortunate that the connectors stick out of the rear of the base as that pushes it a couple of inches further forward than I'd prefer, but no big deal.
- It's very bright, had to dial it down to under 50 (set to 48 with contrast at 70)
- General image quality is very good, ran a couple of games and they looked better than on the 2405, even with the caveat below
- Sharpness isn't as good as the 2405. Guess that might be due to a slightly lower resolution (1920x1200 v 1920x1080) and a bigger screen. Increasing sharpness seems to bring a pink/red tint to text on the desktop so I have that at 68
- Viewing angles good when sat back, but when sitting close to the monitor the lower corners appear slightly dark. Was the same with the old 2405 though.

One thing though, I've attached via DVI and can run 1920x1080 @ 60Hz OK but when I switch to 120Hz the display is awful/distorted. My graphics card is a GTX 280.
I gues it needs to run at 120HZ for 3D as well, tried it and the flickering was crazy, but guess that's because the 60Hz is being halved.

You need to use a dual link DVI cable for 120Hz.

If you've carried on using your old cable it might not be dual link.

You'll probably find a dual link cable was supplied with the monitor.
 
I'm using the DVI cable supplied with the monitor and have now managed to set it to 120Hz. There is a defiite problem with colour though, see the attached picture below, I'm not sure the letters in the browser bar are supposed to be a rainbow of colours. :(
There's a similar effect on text on the desktop.

Make sure the DVI cable is securely connected.

The monitor isn't trying to do some of its 3D stuff is it?

Are you running the monitor at the native resolution of 1920x1080?

Have you tried the other DVI connector on the graphics card? I believe the GTX 280 has 2.

Does the same in the 2nd DVI connection on the graphics card (never had this problem on the 2405 using the first connection).
The monitor's 3D mode is turned off.
I'm running at 1920x1080.
Does the same at 60Hz or 120Hz.

Tried this with my laptop and got the same result.
Picture of desktop icons showing red fringing to text. :(

Hate to think I'm going to need to RMA this.
 
How have you got the monitor set up? Sometimes you get coloured flares on small areas of white if the contrast is too high or if the colour balance is way off. I would suggest turning contrast down to 70-80 (default 100) and then seeing if that helps. Then try reducing the red channel and perhaps green channel colour a little - also change the Gamma to 'Mode 3'. If you still have this problem after fiddling about like this then I'm afraid RMA is the best option. :(
 
Thanks for the advice.

The out of the box settings are crazy. It's the same with LCD/LED TV's, first thing you need to do is dial everything down.
I've got it set to
Brightness: 48
Contrast: 70
Sharpness 60. This reduces the fringing a little but everything's too soft for my liking, will set it back to 68.

I've set Gamma at Mode 3 and it does look better.
I've tried dropping the red ands green channels a little, but there's some blue fringing becoming evident as well after making those changes.

That's interesting. What happens if you do the following:

- Keep the Gamma at 'Mode 3'
- Set the 'Colour Tone' to 'Cool 1'
- Reduce the green and red slightly (to 45 each, for example) without adjusting blue.

If that doesn't help you could try reducing all of the channels but keeping 'Colour Tone' at 'Normal'. The problem with having to reduce the colour channels too much is that it affects the white luminance itself and will start to compromise overall contrast. It could be that your unit was just particularly badly set up in the factory which is annoying. :(
 
Setting colour to Cool 1 also set red to 34 and green to 37, I set them back to 45 each as there was still some coloured fringing.

Driving me mad this is. Some things look great (tried SFIV last night) while text has colour fringes.
There's none around the white text on the forum though. But black text on white background in Excel / Word just doesn't look right.
