External display Flickering (2020 M1 MacBook Pro)

I'm using LG 24GL600F-B UltraGear Gaming Monitor 24" FHD and the display keeps flickering and the text is not very pleasant on the eyes. I have tried 3 different quality hubs and HDMI cables but unfortunately, none of them works. I had to switch to another monitor ( ASUS VX238H) which helped a little but still can't get a good looking text. btw I have also tried different resolutions and also the resolutions that don't show up in the menu by default, spoiler alert didn't help.

The cables you want for HDMI-only Monitors (higher resolutions than 720p TV sets) are marked as Certified with an anti-counterfeiting tag and are labeled:

"Premium High Speed HDMI cable" or that + "with Ethernet" --OR--

"Ultra High Speed HDMI cable" or that + "48G"

Cables with No Certification tags are good for your standard 720p TV set, and not much more.

I am not trying to start a shoving match over this. Use whatever cables you like.

But when things are not working correctly, my approach is to make sure that whatever you CAN control is at least up to, and when possible exceeds, applicable standards. Certified high speed cables for resolutions above 720p are the appropriate cables.

What adapters are you using?

the cable I used was mostly originals that came with the display and I used to play 144 FPS games with them on my previous laptop without any flicker or hiccups.
