You would need 75 posts to be able to PM someone. Even then we don't allow using the message system for individual help. What you can do is upload your Clover Config.plist for review. Also tell us what specific version of macOS you are running.

This is not the ideal choice of SMBIOS. You have a desktop system that is closest to iMac 13,1 or 13,2. Uncheck the Mobile box and switch to one of the iMac system defs. then reboot and try again.

Try unchecking the box for Load Vbios and then reboot and see what effect it has.

Try a lower 1080p resolution and see if it works normally.

1080p at 60 Hz worked from the very first time. But at 1080p resolution in the big screen, the fonts and words look brittle and broken and causes strain in the eye over a period of time. Do you think it has something to do with Dual Link and Mother board bandwidth. Thanks

The pixel density of a TV is too low for the text to look good when running macOS or Windows. Especially those TVs 40 inches and up. They are designed to make video images look good, not small text. What is the brand and size of the TV ? Does it have a PC mode that you could try ?
