Ask HN: Good projectors for showing code?

1 points by copperx 7y ago ↗ HN

Hi,

I'm in the position of being able to select projectors for our new Computer Science/IT building at the two-year college where I teach, but even after reading many guides, I don't know what to look for.

Our current projectors are XGA (1024 x 768) and are only usable at native resolution. And because the instructor's screen is mirrored, the screen is horribly scaled too.

The natural thing is to request 4k projectors for the classrooms, but the ones that are "true" 4k seem to be closer to $10,000, which is out of the budget and likely they will be overkill.

Will a 2k projector suffice? what are some good brands? any suggestions?

While that's probably not what you want to hear: Why not fix the software issue with the XGA projector and then create slides with not less then ~23pt font size for the code?

This is a trivial remark, but: Better show less code, with foreground and background colours, bold font, etc. -- showing too much code on a slide is like showing too much equations: it takes the audience a lot of time to read and understand your slide. Certainly too much time, compared to the speed you wanted to rush through the your slides ;)
