Hey'all,
Been wrecking my brain trying to solve this one and about to give up....would love some help - thanks!!

my problem:
unable to setup a dual monitor using the daisy-chain option - monitor are showing duplicated display (i want extended display). windows is detecting only one screen.

my setup:
Windows 10 - updated when asked
Quadro 600 - latest drives
2x Dell dell u2414h screen - plugged in the right the way. DP 1.2 is enabled on both monitors.

Thanks :)

It may be possible that the display card cannot support the bandwidth from the single line. It looks like quadro has a maximum resolution of 2560x1600.

It may be mirroring the displays if it can't support the resolution.

I would try turning down the resolution to 720p and see what happens.

Might seem like a stupid question, but did you change the display option in Windows settings to enable separate displays instead of duplicated?

It could be different with daisy chained monitors but when I first set up my dual-monitors (I used two cables to the GPU) It was almost a nightmare to set up because of the Windows settings messing everything up.

Thanks for answering - windows 10 doesn't recognize the second monitor at all - so I'm unable to change between the options...
There's a detect button but it doesn't seem to do anything

How about monitor settings? Is there anything in the OSD menu that looks like it may enable a DP chain?

Do you simply have the option to just use another DP slot on your card?
I'm not sure of any benefits if any of using a chain vs plugging them into their own slots. But then again I have 3 DP slots on my card.

The quadro 600 has only 1 DP and 1 DVI :(

Quadro 600 maximum display resolution digital @ 60Hz is only 2560x1600px, you're 51.200 px short (1920x1080px*2). Try lowering resolutions. If that doesn0t help just buy new GPU, Quadro 600 is +10 yo card Daisy chain is quite new solution, it could also be support problem.
