Confusing GTX460 max resolution

Guys i'm a bit baffled, i'm debating adding a 4th monitor to my work PC, but after checking the specs of my GTX460, i am a bit lost. I'm currently running 5760x1080@60 across 3 1080p monitors, using only one output from my GFX card and going into a Matrox triplehead splitter. I did this because i knew my card only supports a max of 2 monitors connected to the card. So my thinking was that i can still use another port from the card to hook up a 4th screen. I knew that this would mean contending with the max resolution of the card instead of max number of ports, so i checked that online, and nvidia claim the GTX460 has a max digital resolution of 2560x1600@60....... How then am i pushing 5760x1080@60 to my 3 monitors ? 

 

Baffled, help plz :)

What are you doing on the three displays?

Why do you need 4 monitors? What are you doing, stocks?

GTX460

 

I'm a computer systems engineer, i have an RDP on my left screen, outlook on the right, and current work on the middle. I also use the middle display as a test monitor for checking laptop video outputs and stuff.

 

I wanted the 4th screen so that when im testing on the middle screen, i can put what was previously on that monitor, up to the 4th monitor, and use the middle 1080p for testing.

 

Hopefully this pic will sort of explain what im doing.

 

Either way im still completely befuddled as to how i am pushing so many pixels out of a card that clearly states it can only do 2560x1600@60. With all this hooked up, im running 5760x1080 plus 1280x720 all at 60hz. How is this possible ?

The card could be a defect, or you may just be leveraging an undocumented bug. 

Computers r fun

Those maximum resolution specifications are a little hard to interpret sometimes. It may say 2560x1600, but at the same time the GTX 460 also supports your 3 monitors. And as you've noticed, you can burn through 2560x1600 pixels in no time at all with three monitors and it works fine to do so. So clearly it's not meant to be taken quite as literally as that, but I admit I'm unsure what it really means.

 

Maybe that's 2560x1600@60 Hz per video output? But that could even just be that in 2011 there wasn't much on the market larger than that to advertise compatibility with, for all I know.

yeah after a bit of researching i think that might be the case, maybe when the 460 came out, 5760x1080 was just ludicrous dreamer stuff so they didnt even bother saying it could do it. But as for it being a limit on each video output, it's definitely not as im running 5760x1080@60 down a single DVI cable from the GPU, the 720p monitor is on the HDMI port. I don't know lol, this falls into the category i call "computer ghosts", like Linus' voodoo fraps/vulkan episode lol.

MAX out put means that max resolution and refresh rate on single port is 2560X1600@60hz and its probably the DP connection.

please read before commenting, i have said 3 times now that i am running 5760x1080@60 out of ONE SINGLE DVI CABLE
