High CPU usage with external monitor MacBook Air 2020

When I connect my external HDMI monitor with the Apple usb-C Digital AV Multiport Adapter my CPU ramps up and the macbook is working overtime. Can I change any settings on either the external monitor or the macbook to prevent this?

The processor is IntelCore i5

the external monitor is Philips 243V5LHAB

High CPU utilization by kernel_task process when external monitor plugged in I have a MacBook Pro 16" 2019 i9 Processor with 32 Gig Ram. Whenever i connect an external monitor using HDMI (Dell Monitor) a process called kernel_task starts taking very high CPU (says 1000%) and all the applications become very slow. As soon as I unplug the monitor the CPU utilisation of kernel_task reduces and everything is normal. Because of this i am not able to use the external monitor. The issue was in Catalina OS and also in Big Sur. Seems to be a very old issue. Is there a solution/workaround for this?

I have an intel macbook air with ventura 13.2.1 and with the new OS updates I have seen several software compatibilities problems and degradations. One of them being that I cannot connect an external monitor or the kernel_task process starts claiming 600+% of resources :) With this most likely being a software issue that apple should address could you please confirm what to look into? I have tried resetting the SMC and NVRAM but made no difference. The laptop becomes useless when i connect to the external monitor so hopefully someone here can help to point out the fix.
