Unsuitable Screen Resolution

I've just installed eOS. The initial screen resolution is a lot lower than the optimum for my screen. The system doesn't seem to recognise the screen mark and model, and I can't find a means to do that within the System Settings. So, how should I do that? What should I read?

Thanks a lot in advance.
