TV vs Projector – There is no right or wrong. It’s a personal choice.



There are three types of technology in front projection: DLP, LCD, and LCOS.

LCD is basically the same technology used in flat-panel TVs. Typically, LCD projectors are in the low to mid ranges of the price spectrum. Where they once were strictly in the budget realm, steady improvements have resulted in some models being the best in their class. Epson, for example, has put out several excellent projectors in the past few years.

DLP, or Digital Light Processing, uses small chips with millions of tiny mirrors. They range in price from ultra-low-end models to extremely expensive, three-chip flamethrowers for dedicated theaters. Digital projection in movie theaters is most often DLP. Their black levels and contrast ratios aren’t as good as those of LCOS or many LCD models, but motion resolution is way better. As they’re made in such a range of quality levels, it’s impossible to say DLP is this or that, but typically picture quality is very good.

LCOS, or liquid crystal on silicon, can be thought of as a hybrid of DLP and LCD. It’s a liquid crystal layer on top of a mirrored surface. Black levels and contrast ratios are both excellent. JVC projectors (using their version of LCOS, called D-ILA) have consistently had the best contrast ratios I’ve measured of any display type. Sony’s version, called SXRD, is a close second. Prices range from midrange to upper midrange, though Sony’s new 4K projector is way high-end in price.

Do your research to get a better price and  a quality projector. There are many brand out there in the market but I would recommend to pay closer attention to Sony, Panasonic and Epson. Also worth to check out Sanyo – Easy DIY installation due to advanced lens shifting


I cannot explain all the technical aspect of between 1080i and 1080p. Both are 1,920×1,080-pixel resolution. Both have 2,073,600 pixels. From one perspective, 1080i is actually greater than Blu-ray. And, you can’t even get a full 1080p/60 source other than a PC. 1080i and 1080p aren’t the same thing, but they are the same resolution.  I have 1080P and happy with it. To be honest I cannot tell the different. Do your research about the resolution. As for games it doesn’t matter, I believe you will never get the best resolution than a PC.

Easier on the eyes

Everyone always asks if having a screen that big hurts the eyes. Actually, it’s the opposite. Filling a larger percentage of your visual field, and with less overall brightness, a big screen actually quite relaxing to watch. More like an actual movie theater, which often produces no more than 5 foot lamberts or so (on my screen, most projectors produce around 30 to 40; an LED LCD can be three times that or more)

Screen Size


Screens range in price from a few hundred to many thousands. Whatever you do please don’t use the wall or DIY screens. Even if you spend low price screen much better than making one. Dedicated screen will usually produce much better contrast and image brightness. So trust me it is worth to spend the money on the screen.

Buying tips: focus on Brightness , screen option and connectivity.

Why TV

There are cons having a projector. hard to fit in small space, also need to consider Light, Lamp life span, Sound, throw distance and Fan noise.
