Join Mike Meyers for an in-depth discussion in this video Projectors, part of CompTIA A+ Exam Prep (220-901) Part 4: Displays and Printers.
- I've dimmed down the lights a little bit…in order for us to talk about projectors.…Now, what I've got in front of me is a oldy-goldy projector.…It's a Hitachi LCD projector.…It's about six, seven years old,…but it's perfect for what we need to talk about,…certainly enough to cover the A competencies.…So, first of all, what I want to talk about…is that projectors like the one I have here…have, more than anything else, if you're going…to be picking one big issue for a projector,…it's going to be resolution.…
This oldy-goldy here has a whopping 1024 by 768 resolution.…Pretty low-end stuff.…I can't do high-definition video with it,…or I can, but it doesn't look very pretty,…and as a result of that, he's good for…doing videos on how to work with projectors,…but I would never be using this full-time right now.…The other big thing to watch out for…with projectors is lumens.…Lumens is the brightness that the projector…can actually fire out onto the screen.…Back in the old days, lumens were measured in the hundreds.…
