Hello Wei Liang Ashton Lim.
Welcome to Microsoft Community.
Regarding to your information I assume that you have some issues on Edge's resolution.
According to our testing, the website's resolution is calculated based on your screen resolution multiplied by the scaling factor minus 1.
For example, if my computer screen is 4K with a scaling factor of 150, then the displayed resolution on the website would be equivalent
to a 2K screen resolution.
Regarding the font issue, you can try adjusting it here to see if it becomes clearer.
Access this website and then search this feature turn on after that open the Clear type.
edge://flags/
Enhance text contrast
And set the fonts in this website.
edge://settings/fonts?search=Fonts
If there is anything not clear, please do not hesitate to let me know.
Best Regards,
