Has anyone tried whether Intel Iris Pro found in 2015 retina MBP is powerful enough to drive single 5K screen like Dell UltraSharp UP2715K or Iiyama ProLite XB2779QQS or Philips 275P4VYKEB or HP Z27q? (basically all the ones that aren't relying on usb c/thunderbolt 3 connector like LG 27MD5KB-B UltraFine)?
I'm trying to find an external screen for my MBP and unfortunately due to macOS/OSX's focus on retina screens, non retina screens (fonts mainly) look pathetically bad, whereas Windows (even launched within OSX via RDC) looks sweet. So the only option is to either go 4k but that means usable resolution would be 1080p or 5k with usable 1440p. Hence I'm wondering if it can drive 5k screens.
