Yet when I try to install new settings to SwitchresX even after installing the patch I get " Not Activated-Invalid" error every time. Of course higher is better, but this is more than enough :) I need at least 502.89Hz in order to get 60Hz output at native 4K resolution as it can be seen from the config below pushed to the lowest levels at 60Hz. Yet since I have this device why shouldnt I benefit from all the performance I can get.Īt this point I was hoping that this patch would help me to increase system Maximum Pixel Clock output above 450Hz. )īest 60Hz resolution I could get so far is 2560 x 1440 ( 720P HiDPi) which is fine for movies etc. This is a perfect solution for all 4K monitors except the one I owe. So all you need to do as a regular rMBP user is to install SwitchresX and tweak to 52-53Hz, which is much better than 30Hz, and still under the system pixel clock limit of 450MhZ Other 4K screens like Samsung accept variable frequencies. This screenshot is from the manual of the UP2414Q explaining frequencies supported. : Dell 2414Q does not accept any other frequency for 3840 x 2160 than preset values of 30Hz and 60Hz.: Max pixelclock set for my rMBP 13 is 450MhZ.So I am guessing I have two constraints here. Hi again this is an issue of every Mac 13" User. By then there will be reasonable priced IPS or better 4k labels on the market, right now the only decent sub $1000 dollar panels seem to be TN. When thunderbolt 3 comes out i will upgrade to 4k/5k panels, a new mini or macbook with crystalwell. I will sell both my existing thunderbolt displays to pay for it. and even then the best case scenario would be 4k 30hz over both screens.i decided because I'm in front of a screen ten hours a day, that it would be harmful for my eyes squinting at 30hz.I went with quad 2560x1440, out of the box yosemite will do over hdmi, and 60z over display port.thats a worse case scenario i can deal with. However the 4k over HDMI would be stuck at 17 hz unless the yosemite pixel clock limit can be cracked. Īll updates to all 4.x versions will remain free for you.Honestly from what I'm reading it would be possible to do dual 4k,there are tons of forums with guys who have 4k displays running over either interface with a 2012 mini.however none that I read with Yosemite.and none simultaneously, but according to intel's docs its possible.
