I think it's because the early 2013 rMBP is limited to DP 1.1a, according to Dell. I am now using 2304 x 1296, HiDPI, at 30Hz. SwitchResX did help me get more resolution options than the standard display settings would. The cable I'm sticking with is the Startech mDP to DP, and the HDMI cable I tried was a 4K Belkin HDMI cable from the apple store. This LG monitor has DisplayPort 1.2 and HDMI 2. I could not get 60 Hz on any cable at 4K. I ended up using a BMD Ultrastudio SDI via USB 3.0 to output Pro Presenter via SDI.On my early 2013 15" rMBP and LG 27UD88-W 27" 4K UHD Monitor, and SwitchResX, I tried mDP to DP, HDMI to HDMI, all 4K compatible cables, and finally active mDP to HDMI 4k 60Hz cable. Just couldn't get a picture to show up on a ME 2 4k. I can't remember for sure, but I don't think it was playing nice with my Macbook Pro via HDMI 720p 59.94 SDI out. I have a feeling it would increase the price quite a bit. Even Tricasters can do it, Ross Carbonite etc, but they are much more expensive than BMD. I think that's what sets the higher end switchers and BMD switchers apart is the ability to accept all different types of resolutions. Though I can see them not mixing the ntsc and pal ones together. If you are 29.97, 59.94, 30, or 60, progressive or interlaced, it should handle it. The old ATEMS did that, when they were owned by EchoLab. You should be able to mix resolutions in these units. In fact, they ought to handle completely different resolutions without a hiccup. That said, I also think the ATEMs should all be far more forgiving on their inputs. That is screwed up, and obviously, OSX has somehow screwed up the output. I really think it is odd that the macs are not outputting something that the ATEM 4k will accept.

I will try and get our profile saved and can then email/ Dropbox this if you need them. This is a cheap fix for getting graphics into the Atem that you can't store in the media library especially for animated lower thirds when using the TVS as this can't store animated graphics. We use the SwitchRes on the second screen output as 108050i so that it matches our regular camera settings, but then keep the primary screen at 1080p as this is a slightly better viewing resolution in our trucks. Save the SwitchRes profile and set it as the default settings for your machine Make the secondary screen settings the same as the input required for your Atem - exactly!ģ. Make sure the settings you are changing on SwitchRes are for your second screen output not the primary.Ģ. The biggest problem with the Mac mini is the second screen output switches from the HDMi to the thunderbolt at set up which throws things a bit.ġ. I too couldn't get the standard Mac profiles to work and at $30 or so for the software it was worth the try. We had a few little glitches getting switchers set up to begin with but now all is simple. We have a selection of Atems 1me, studio 4k and tvs's. We have used SwitchRes for some time on all of our machines. I'm not in front of any of our BMD Atems at the moment to give you exact settings but it's not too much of a problem. Hope the reply isn't too late to be helpful.
