1. My monitor resolution may be too high, but I can't read some LaTex.

Can it by default be made larger?

It hurts my eyes to try and read.

2.

3. A handy tip for those posting Tex code: if you use the \displaystyle command it will stop the system trying to squeeze the equation into a single line. (Thanks to Markus for pointing this out to me!)

4. I have the same issue as in the OP when browsing from my phone, the tex equations are tiny. No problems on my PC / laptop though.

5. The Large command doesn't work

\Large \frac{\alpha ^e \infty ^{1/\mu }}{\frac{\pi }{e}}\leq \int_{\psi }^{\sigma } \zeta \, d\gamma

6. I don't know if this thread got any attention, but here's an example: Non-inertial clock orbiting an inertial clock: "Do moving clocks always run slowly?"
