Little tricks such as trying all USB-C ports, rebooting and reconnecting everything and booting in safe mode are to no use. I know for sure that the adapter works properly, as I have two of them which both worked before. Normally it automatically detects a source and switches to that mode, but I also tried manually switching to DisplayPort as an input, after which I immediately receive the message of no signal being found. The external monitor does not show up in the 'display' section, and when connected and turned on simply goes to sleep. Since the 'update' to High Sierra (which I cannot revert, since it shipped with this OS X), my MacBook Pro 15' (2017) does not recognize my external monitor anymore using the exact same method I used before ( USB-C to DisplayPort adapter). This one shipped with High Sierra, and is now running version 10.13. Eventually, my 2016 model got replaced by a brand-new 2017 model. The MacBook Pro was running Sierra as operating system, and it recognized the external monitor.Īfter I went through a bit of technical problems, however. It was a USB-C to DisplayPort adapter, after which I used a DisplayPort cable to connect it to my external UHD monitor (Philips Brilliance 288P). I purchased an adapter so I could connect it to my external monitor (which functions perfectly). I have always heard an audible sound when turning on any computer.A bit ago I purchased myself a MacBook Pro 15' (2016). i have never turned on a Windows 10 computer, but i do not get any audible sound from any speaker when the computer turns on. No fans inside move & i hear no sound that anything is happening inside the computer. Does anyone have any suggestions how i can get the monitor to work with my new computer? btw - the only evidence i have that the computer is on is that the keyboard lights up. I am not sure what the RAM would have to do with the output of the video card. I have reseated the RAM as per Technical Support but Technical Support seemed more interested in getting off the phone with me than solving my problem. I have cycled the monitor through the inputs it has & still i am not able to get a signal. I have the monitor hooked up to the display port & the HDMI port (both below the audio input/output). When i turn on the computer, i get a blank screen on my new monitor that says no signal is detected. I received my new cyberpower pc Model GMA8200CPG & i got a new monitor ASUS VG248.
