View Full Version : Quick Question Regarding Secondary Screen

06-25-2012, 01:11 AM
I had a thought when considering whether or not to keep my current G74SX, upgrade to a G75, or upgrade to a desktop machine. I think trying out 3D technology would be fairly neat, and I thought that I needed either a G75 or a desktop as I do not have the 3D capable G74, but now I realise perhaps not.

Would it be possible for me to buy a 3D capable 24" screen, hook it up to my G74SX via the VGA cable, using a DVI adapter if necessary, and be able to watch 3D content from compatible games or Blu-Rays once the NVidia drivers were installed, or is the graphics chip in this machine incompatible with 3D output?

The graphics card (GTX 560M) is perfectly capable of supporting 3D, and yes, VGA will work. My advice, however, would be to go with HDMI. HDMI is an all-digital connection, which will give a better image quality, and the cables take up less space. The newer nVidia drivers include 3D support natively, they just do not turn it on when none of the attached displays support 3D.

Be aware that HDMI 1.4 of the G74SX will limit the resolution of 3D you can display on an external 3D capable monitor or HDTV to 720p60 or 1080p24. See

That's really helpful guys, thanks a lot. I was aware of HDMI vs VGA, or so I thought. I would be wanting to play games over this connection, so the HDMI is not an option as games at 24FPS look terrible when the option for 120FPS is around, which I believe means that I will have to go with the VGA-DVI. Will this give me a dual link signal through the DVI for 120Hz, or not?

As a side note, I just flashed my BIOS for that CPU throttling fix and two hours of TF2 took the core to 80C, which is too high for my personal comfort. Is there any way of forcing the fans to maximum software or hardware based, in order to eke out some extra cooling?

From what I understand, you need a dual link DVI port to achieve 1080p60 on an external monitor. The G74SX don't got it, so you aren't gonna get it...

No DVI, but I do have a full 15-pin VGA...

Please for give the double-post and the necro, but I find myself NEEDING a definitive answer for this. My G74 DOES HAVE a 15 pin analogue VGA output, and from what I can find online the VGA standard has no limitation on refresh rate or resolution besides that imposed by the image processor chip in the graphics card.

Will I be able to get 1920*1080p@120Hz output via VGA - VGA>DVI adapter - DVI input on the screen?
