Secondary display goes black on wakeup

I recently bought this MacBook pro 14' 2021 model. I have it connected to DELL SE2419HR via the dedicated HDMI port with a standard HDMI cable. While the normal usage, it works seamlessly even after 10hours of use.

The issue is happening when I sleep/close lid the mac and wakes it up later. At the time of wakeup, the secondary display powers on and with a completely black screen. however, I can move the mouse from the in-built monitor to the secondary monitor but nothing more or less. The only working solution for me is currently to unplug the HDMI cable from the laptop and replug it. This does not happen all the time either, it only occurs in random wake-ups, more like 2-3 times for every 5 wake-ups.

This extremely frustrates me when I open the laptop for something quick and the second monitor suddenly shows black so that I need to do the above routine which is very inconvenient. I can assure that the cable is in its best condition and has no damages or anything. and this problem occurs only at the time of wakeup.

Any help would be appreciated if this is identified as a current issue or something.

Have a great day,
