That weird little rainbow circle on a motor thing in the picture below? That's the color wheel for a DLP projector. More to the point, it's the color wheel that's going into my projector. It's twee and fragile, and I'm sure the old one made the tiniest ping when it shattered. I didn't hear it... but I didn't need to. The results were pretty obvious when I fired up the projector to watch a movie, and the screen was 50 shades of grey. (Sorry, couldn't resist.)
The wall of grey led to two things. First, I borrowed a gorgeous 55" Samsung Plasma TV. Second, the realization that 55" is way too small for an HDTV when you're used to 100 glorious inches of 1080p color blanketing the wall in my living room.
We'll talk about the color wheel another time, but it was the 55" TV that got me thinking: most people buy televisions that are way too small for the room they put 'em in. So, my simple advice: buy a bigger TV than you think you need. Seriously. All too many people say "gosh, that thing is huge" or "60 inches? That's ridiculous!" while they're wandering through the TV aisle at Costco or Best Buy.
This makes some sense. People who grew up with standard definition televisions remember a time when a 37” TV was too big. That’s a fair association; back in the CRT days, 37 inches was massive. A TV that size was also a couple feet deep, so it literally took up a lot of space in the room. And more often than not, living room CRTs were stuffed inside some huge piece of furniture to hide it when it wasn't on--which took up even more space.
People who grew up with big CRTs need to rewire how their brains think about screen space in relation to TV sizes.
Going much for a bigger screen in the days of VHS and DVD usually meant rear projection. These were massive boxes that hulked against the wall. We're talking a couch worth of floorspace...great for baseball games. Not, to paraphrase Loyd Case, so great for the Spousal Acceptance Factor.
And in defense of spouses, husband or wife, a big blank 60" screen tends to really overpower a small living room. Which is a shame, because the higher resolution of HDTV (much less UHD/4K) means you can sit much much closer that before bigger screen stops looking really good. A 1080p screen displays 1920x1080 pixels, nearly six times as many pixels as 480i (let's agree that 480i, or 704x480 at 60 interlaced frames is roughly 'standard def' in a digital format). People really need to rewire how their brains think about screen space in relation to TV sizes.
