Re: Macbook Pro 16" is HOT & NOISY with an external monitor! :(

I experience the same with the base MacBook Pro 16" with 5300M GPU. Single external full HD display raises the GPU power usage to 18W when the device is idle. This makes the laptop very difficult to use for longer periods of time.

Re: Macbook Pro 16" is HOT & NOISY with an external monitor! :(

I have the exact same issue below.

The Moment I connect my MBP 16" 2019 (5300m) to an external monitor the GPU immediately begins to draw about 18W resulting in a temperature increase of 20C in normal usage and higher fan speeds.

With the laptop screen open and external monitor connected, using chrome, and a code editor, the MacBook it's overheating with fan activations and overall high wattage consumption.

MacBook Pro 16" (2019) - AMD Radeon Pro 5300M 4 GB
External Monitor: 24" Asus VS 247 - 1920x1080 / 60hz
Connected by original Apple adapter USB-C to HDMI

I am almost sure Apple receives driver from AMD and then it gets embedded into OSX. Still AMD and Apple should work together since it's clearly AMD hardware causing the issue.

I agree. This is a very fundamental issue which would have been quickly identified by any user after several minutes connected to an external monitor. Total schoolboy error and rookie mistake to miss such a glaring problem. Not a good look for Apple and/or AMD

I also have this issue.

Macbook Pro 16, base model with 5300M.

AMD has to take care of it ASAP. Apple ignores us, they labeled it as a low priority issue.

I have this same issue with the 5500m 8GB.
It's very annoying that I'm not able to use the built-in keyboard when using an external display because how hot it gets.

True or not, AMD is the one getting the bad reputation. As a customer I feel like I would never want an AMD anything in my future computers. BECAUSE IT DOES NOT WORK.

AMD can fix it. Apple can fix it. I don't care who does the work.
