High-resolution logo looks pixelated

High-resolution logo looks pixelated

I have uploaded my logo to Meeting but, when it appears on the embedded registration page or on emails, it is badly pixelated. It looks very uinprofessional.

I have tried uplaoding a 96dpi and 300dpi version of my logo. The result is the same.

I have inlcuded a screenshot of the way the logo is presented.

Is there any way to cure this problem?

Many thanks

Steve
