<p dir="ltr">Hi<br>
If u want to use eprime then, AFAIK, you will need to do some basic trigonometry to convert angles into mm and then into pixels.<br>
You might like to look at PsychoPy instead though. It has the concept of monitor dimensions and viewing angles builtin so this may be a lot simpler. Its free too :) and works across all platforms too.<br>

How to I convert this into pixels exactly? I'm assuming the size (height and width) in properties are in pixels too, right?</div>
