Hi All

I have 2 screens connected to my laptop using the HDMI output and Display Port, I really wanted to buy a third screen but where do I put it :)

I know D-SUB can support 1080p resolutions but does the D-SUB on the M17x R4 allow it and if so will all 3 monitors be using the GTX680M and how owuld it perform?

Any advice/information would be appreciated.
 
Yes 1080 will work via VGA
I run VGA on my M17x because my HDMI on my BenQ BenQ XL2411T(120hz) does not scale properly, there is around an inch of black, same thing on my Sony 40" TV, same thing on anything I use the HDMI output at 1080
Also I should note here, I cannot get 120Hz out of HDMI/VGA at 1080 out of the M17x, only at 800x600 which is a shame, the BenQ BenQ XL2411T is one of the worst gaming screens at 60hz. In order to get 120hz I need a DisplayPort to DVI-D Dual Link Adapter which is £40

Three monitors shouldn't actually make a noticeable impact on performance. Especially with the 680M. Also, wont you be runnign 4 screens if you include the M17x screen itself? that some setup you have there

Hi roughavoc

I have 2 24" Asus Slim Bezel 1080p screens connected right now what I wanted to do was connect a third but then I won't use the laptop screen while it is on my desk so it will be running at 5760 X 1080, I just wanted to make sure it will work before I buy another.

Not sure how the 680M would work with this resolution during games?

Thanks
 
Oh running games at over three screens, I thought you were asking if there would be a performance decrease by just having three plugged in.
I think you might run into problems at that res, youre going to maxing out the VRAM and on games where youre not already getting 100+ fps youre going to notice a major hit to the FPS.
There arent many mobile benchmarks but looking at the 680 Desktop, Hexus had 680 running BF3 at 60fps at 1080 and a horrible 25fps running at 5760 X 1080. Now I think the difference for you wont be that drastic due to drivers plus you have 4GB of VRAM compared to the 680 Desktops 2
 
Was that with everything on high settings?

I am not that bothered about playing games, I only play very occasionally but it would be cool to use all 3 monitors but not essential.

I just found an old LG 23" 1080p monitor and plugged it in, it runs fine with the 3, just got to try a game now, I am installing BF3 so I will let you know soon, I am not expecting good things though :)
 
Sadly it doesn't, I had a look around and the GTX680M does not support surround monitors so you don't get the option :(

Might have to break out my desktop again for gaming :)

Is it an AMD eyefinity only kinda thing?
How did Hexus manage to get three screens on the 680 Desktop S:

The 680 desktop has surround support (like eyefinity), the 680m doesn't.

I have a 6970 lightning in my desktop so I think I will use that for gaming using eyefinity.
