Yes, but only at 4K30 via HDMI 1.4. If you want 4K60 out of the iGPU, you need a mobo with DP output, and you need to use an (active) DP-to-HDMI2.0 converter, such as the Club3D model (popular). That's what I'm doing, with some G4600 CPUs.
Either that, or get a GTX 1050 or RX 460 for display output purposes.
