is it true a 720p projector can beat 1080p?

[Anthony P]

What exactly do you mean by "min criteria"?

there always has to be some min criteria. Like my previous post, if you want a 20' or 30' image you should not be looking at a <1000 lumen projector, it does not have the brightness required for the job. You should not compare calibrated to none calibrated, broken to working properly....

are many factors involved in the quality of the image a PJ throws

agree

As I stated previously, if all other things are held equal, then yes, a 1080p PJ will best its 720p counterpart, .....

you reraly don't get it.

did you read my other post? https://forum.blu-ray.com/showpost.p...4&postcount=20 from what you replied obviously not.


1080p is not only better because of pixel density. It is better for many rerasons

1) pixel density (might as well get this one out there first)
2) spacing between pixels (i.e. grid lines/ SDE)
3) newer tech vs older decrepit tech (you talked about Sim2 C3X but the newer model is 1080p, if you like their product and that line then why have a projector that is a few years old when you can get the newer one with all newer tech inside)
4) processing vs 1:1 mapping. (i.e. your BD disk has 1080p info on it, to show it on a 720p you must kill and destroy some (more then 1/2) of the detail in the shot

You talked about light path and lenses and processing and all that, I am guessing you know that pixel stands for picture element and describes the smallest item of information of the pic. now a 720p has less then 1/2 the resolution of a 1080p projector and what is on the disk. Let's say that the disk has info that two consecutive pixels in 1080p need to be different (i.e. for an easy example one is white and one is black) since 720p has less then 1/2 the resolution those two need to be combined (it has 1/2 the resolution it happens for around 1/2 the pixels of the 1080p image, it is not as if this scenario would be rare or something.) can you explain how due to optics or colour accuracy or what ever other mumbo jumbo black magic you believe that the fancy 720p projector can do that I will get a more accurate representation of those two pixels from a 720p projector then any none mis working 1080p projector?

What do you mean by "colour accurate enough"? You mean for the average consumer out there?

no, what I mean is that colour and accuracy are oxymorons. Our (human) eyes are not as good as we would like to think when it comes to colour. So visualy colour accuracy is not that important (but I still beleive in ISF calibration since the human eye should be the limiting factor)
I am sure we have all seen these before


blocks A and B are the same shade


there are only three colours, not 4


the centre of each cross is the same colour

colour (like size) is determined much more by its surroundings then some chart of absolutes. Which is funny when some guys talk about colour accuracy as being the more important especially when you also consider that you don't have pixel accuracy so colour accuracy is impossible (i.e. there will be areas where the colour is not what it should be because the pixel info is wrong to begin with).

But, let's say we end up comparing a color accurate 720p projector versus a color inaccurate 1080p projector-- what image would be better then?

all else equal, and unless you are talking about a simple monochromatic pic, the 1080p, sooner or later (in the pic) the 720p will need to kill borderline pixel info and those should not be slightly off (like faulty colour accuracy) but completely off.

Either way, the OP asked "Is is true a 720p projector can beat 1080p"

I know, and I answer the question in my first post

Bottom line: there are a number of high quality 720p FP's out there that will do justice to some very fine theaters and better fit some people's budget. Just because it's 720p doesn't mean it's an outdated POS. Spend some time viewing the image and let your eyes do the "talking".

actually that is exactly what it means. Projector tech moves way too fast, yes a 20k 720p will most likely have some benefits and features over a 2k 1080p but if you have that 20k why not spend it on a 1080p projector and why compare it to the 2k 1080p and not the 20k 1080p. Someone would either need a very restricted budget, a specific device for a particular job where no 1080p projector exists today or to be stupid and a poser (if he goes high end) to get a 720p projector. Like I said before pretty much in every market there are 1080p projectors that can do the job, you are looking for high end, there are 1080p projectors in the high end, you want bright for big screen there are 1080p projectors that fit those criteria, you want under 2k$ there are 1080p projectors in that price category.... The only reason someone would get a high end 720p projector is that they want to pretend they care ("look I have the expensive brand...") but that they are posers and don't want to spend what it takes to get the quality they are pretending they care about ("....but I bought a used 3 year old one for cheap").
