Primary screen blinks after computer wakes (macbook pro 2020 M1)


Everytime my macbook pro goes to sleep and I wake it up, the primary monitor constantly blinks on and off. The only way to stop this from happening is to disconnect the monitor and plug it back in. Is there a way to fix this?

I am running a LG 4K monitor over HDMI for the primary and a Dell S2740L 27inch as the secondary. The LG one is the one that continues to blink.
