Projector vs large TV - Bang for buck

The advice iv found online is this:

The more you zoom out the softer the picture will become. Ideally, it's best to not use zoom if you can get away with it. The closer the projector is to the screen, the brighter the image, the further away it is, the duller it'll become. Obviously moving the projector closer to the screen will normally need the use of the zoom facility.

So does that mean I should place projector as close as possible to the screen with only a 1x zoom or furtherest away from the screen with a 1.62x zoom for best results?! Im so confused.

I am right in thinking 1x zoom is LESS zoom than 1.62x zoom right?! And why can't I set the zoom to 0 i.e. no zoom. Or does 1x zoom mean no zoom?!

1x should mean no zoom. Honestly I wouldn't get to concerned about it - aslong as you have the projector at a range where you can use minimal levels of zoom and close enough you are getting decent brightness it doesn't make much odds (unless you buy one of those cheapy no name Far East brand jobbies).

You'll probably see more impact from how well you can dial in the focus unless the projector has additional features to aid with that though a convergence pattern can help.

Rroff, thanks for the advice. Doesn't having the projector further away mean less zoom which means better quality image? But then the closer the projector to the screen the brighter it is, i.e. more lumens, which is a good thing right?! Which of the two is more important?

I have a choice between 1x zoom (i.e. no zoom) which gives me a throw distance of 4.7m. Or on full zoom which seem to be 1.62x I get a throw distance of 2.9m. And obviously a range in between.

What would you go for??
 
Naturally I want the best picture quality and sharpness when the curtains are done and I'm watching a movie on it. But then I will be watching some day time tv with natural light coming through the windows so I could also do with it being as bright as possible.

Iv got a 5 meter room so the entire range is available to me. Just can't decide what is best!

Depends on the layout of the room and where is good to place the projector for an unobstructed throw, minimise noise disturbance from it, etc. - personally I'd probably aim for around 4m or so and whatever zoom works with that.

Its a rectangle room with led lighting so nothing in the way. Back wall to front wall 5 meters. So il be sitting about 4.5 meters from the screen (allowing 1/2m for the sofa width). Does that help?
 
Epson EH-TW6700 projector with a Sapphire 100'' fixed screen on the wall directly in front.

I will be using for the cinema experience during the nights with curtains done. But its a replacement for tv so will also be using for crap day time tv. There is a large window either side of the projector screen so during the day there will be quite a lot of natural light coming though. Maybe not sun as that room gets very little direct sun but still plenty of day time light.

As day time is a factor you'll get the best all around balance going closer (~3.5-4m). As its a decent projector and not some cheap jobbie you really shouldn't get a huge difference in image quality in terms of zoom, etc. over a few feet or so difference in position but it can make some odds for day time viewing.

So go closer to what:

4m = 1.19x zoom, max room light 5fc
3.5m = 1.35x zoom, max room light STILL says 5fc
3m = 1.58x zoom, max room light jumps up to 6fc just about!

Seem I have to go at least a meter closer to get the max fc up from 5 to 6. Not sure how much difference that will make in real life?! Doesn't seem like much of a jump in fc.
