Hi all. I'm new to this forum, but a longtime m6700 user. I have 3 of them, that I use for different purposes. One was my main system, but has been pretty much retired. Of the other 2, one is used to record audio at 192KHz and 64 bit float into Cubase 12 Pro, while the other is used to run lights, sound and video for theater productions. All three are configured the same. Win 10 x64 Pro, i7-3740QM, K5000M, 32GB RAM. At home, I use them in a docking station. For a long time I was using them with dual 1920x1080 external monitors into a KVM with 2 video ports, 1 VGA and 1 DVI. The other system on the KVM is a Dell Precision 7920 with an NVidia GeForce GTX 970. Everything with that setup was fine, then I had to go and screw it up. 😬 I needed a fairly large 4K monitor for a play I was doing. I chose a Dell S3225QS, because of the display port. Obviously, once the play was over, I replaced my dual monitors with the S3225QS, and replaced my VGA/DVI KVM with a DisplayPort KVM. And of course here's where the problems comes in. The m6700 will do 3840x2160 from the DisplayPort, but not at 60Hz (I think the max refresh rate is in the 30s). The monitor isn't agile enough to bounce between the refresh rates. There's a Dell forum that claims the E-Port Plus will support dual 4k monitors at 60 Hz with the NVidia card, but I don't get that option when trying to connect any of my m6700s. Am I doing something wrong?
