Tried both manually selecting HDMI inputs using the joystick and using Auto Select.Updated the Spectrum firmware from 102 to 104.Tried turning off HDR in Mac Display properties for the Spectrum.Tried changing the resolution and refresh rate in Mac Display properties multiple times.Tried restarting both the Mac and the monitor multiple times.Used a video-capable USB-C cable from the top of the Mac Pro (bypassing the Radeon card) to (both) USB-C ports on the Spectrum (I know the USB-C port on the bottom of the monitor is the one for video), but I tried both just to make sure. I haven't been able to find anything in 24 hours of searching on certain models just being non compatible or what. I'm using the apple branded dongle, quality new cable, confirmed firmware on TV and OS on macbook is up to date. Strangely, the Displays System Preference DOES show the Spectrum plugged in-it shows up in Displays as an Extended Display that I can rearrange or change the settings to-but there is no picture on the monitor itself (I get the “No Signal” message). Cannot for life of me get this macbook pro to output the hdmi signal to an LG 55EC-9300 OLED Curved TV. I even went out and bought two different 8K HDMI cables (from two different manufacturers). None of them will generate a signal from my Mac Pro.

Since my Windows PC is using the DisplayPort, that leaves me with the two HDMI ports or the USB-C port. I’m replacing one of the Dell monitors with the Eve Spectrum. Or, come back with more details about which mini you are using (model, processor, whatever else you can supply that can help decide what you have.) Some users do have bad luck with some of the cheap import video adapters. I previously had three Dell 4K monitors running from the Mac Pro without issue using DisplayPort to MiniDisplayPort cables. Unless you are lucky, HDMI probably wont work at all - although you could try other DVI to HDMI adapters.

This appears to be an issue with Mac OS Monterey. The monitor itself works fine when connected to an Xbox via HDMI or a Windows PC via DisplayPort, so it doesn’t seem like a hardware issue. Note: Mac Pro has at least one HDMI 2.0 port and four Thunderbolt 3 (USB-C) ports. You can use an external display, a projector, or an HDTV with your Mac Pro. The SSD is completely Blank so I dont know if thats the problem. It is currently connected to a 2012 Apple cinema display that works flawless with my MacBook, and I have tried multiple different cables.

Similarly, does MacBook pro support HDMI The HDMI 2.0 port on your Mac Pro also supports video. Hey everyone, I recently bought a used 2010 mac pro to upgrade and use for work. Finally received my Spectrum 4K today, and I’m having a lot of issues getting it to work with my Mac Pro desktop running an AMD Radeon RX 580 (8 GB) on Mac OS Monterey 12.0.1. Unplug the HDMI cable from your Mac, then plug it in again.
