Simple projector question regarding 1080p

post #1 of 30
Thread Starter 
Some low cost projectors on Ebay indicate a "native resolution" of VGA but also indicate that they are 1080p. Am I correct to assume that this means that I will get 1080p output if I use an HDMI cable thus getting the benefit of my BluRay player? Am I further correct to conclude that if I use component video cables instead, I will only get VGA resolution?

Re: Simple projector question regarding 1080p

Native resolution of the (non-CRT) projector is an important spec. Anything you feed in gets converted to the native resolution (deinterlaced if necessary, then upscaled/downscaled). If the projector has resolution of say 1366x768, but "accepts 1080p", then your end result is still 1366x768 video not 1920x1080. Note that this is still quite an improvement over DVD which is 720x480. But if the projector's native resolution is only say 800x600, then most of your improvement in this area is out the window.

Also I wouldn't trust Ebay specs, which are often written incorrectly (e.g. "native resolution" of an LCD with multiple resolutions listed!); corroborate with the manufacturer's web site.

Component video can theoretically carry 1080p also, but in practice is limited to 1080i on Blu-ray players. This will be deinterlaced by the projector, in theory for film based material it is possible to perfectly reconstruct the original 1080p from the disc, but this depends on the quality of the video processor in the projector. Some people use outboard processors like from Anchor Bay to do this better, or ones built in to AV receivers.

I would NEVER buy a projector from Ebay. What kind of projector are you looking for and what is your budget?

Re: Simple projector question regarding 1080p

I have a 60" HDTV which does 1080i and BluRay discs look pretty good on it. But we actually prefer the quality of ordinary DVDs on our current projector, an Epson which has XGA resolution because we get much more of the theatre experience. However, if anything, the BluRay discs are not quite as good on the projector, they certainly don't seem to be better. Still, I don't really want to spent a lot of money just to see BluRay resolution on a projector. But if there is a low cost projector that will do it, I would buy it. Basically, I think you are telling me that there isn't.

Re: Simple projector question regarding 1080p

I'll ask you again what is your budget for projector? Do you want a 720p or 1080p projector? Remember, there are a lot of extra costs with a projector such as HT receiver, speakers, cables, screen(DIY is good), ceiling mount. Are you able to have your room reasonably dark when using projector? That's a must.

Re: Simple projector question regarding 1080p

I believe I already have a 720p projector. As I said, progressive scanned DVDs look fine on it but I don't see any difference with BluRay. I'd spend about $500 for a projector that would give me the higher resolution offered by BluRay.

$500 is not enough, sorry. What projector do you have?

Re: Simple projector question regarding 1080p

Your projector is only SVGA, 800x600.

You are right, I just looked at the fine print. It's not what was advertised.

Re: Simple projector question regarding 1080p

Obviously 1080p is way out of my price range. But looking at the Sharp Sharp XR-30X, a low cost monitor which apparently has a DVI input, it indicates this in the specs:

Display resolutionXGA (1024 x 768)
Resolution capabilitySXGA+ (1400 x 1050) with ImageACE Resizing

I have no idea what ImageACE resizing means. Won't this give me pretty good HDTV quality from BluRay?

Re: Simple projector question regarding 1080p

That Sharp projector is native 4:3, I would pass on it. Is your budget still $500? Do you plan to sell your Epson? I recommend you buy a 720p projector. I just saw Tigerdirect.com has the Optoma HD70(720p DLP) for $519. It's refurbished with a 6 month parts and labor warranty. If I were you, I'd jump on that.

Re: Simple projector question regarding 1080p

Thanks for the recommendation, I think I'll keep the Epson and use it at our vacation home in Mexico.

Any suggesion for good projector, my budget is around $2000 for projector only.

First you need to decide between DLP and LCD. You can read reviews and learn about projectors at Projectorcentral.com and Projectorreviews.com.
post #16 of 30
Hey Jim Mcc what would you recomend me DLP or LCD? I have check the prices on the web DLp are cheaper i have low budget 1000usd only
post #17 of 30
I recommend DLP. But some people have to use LCD because of their room situation. What are your requirements? Ceiling height, desired screen size, throw distance, etc?
post #18 of 30
There are 3 basic pj technologies you can choose from now
DLP
LCD
LCoS

Each technology has pluses and minuses. DLP used to be king in the area of contrast, and in a certain aspect of contrast (referred to as ANSI contrast) it still is I believe.
The contrast capabilities of a projector (or any display tech for that matter) are important because it has a major effect on, among other things, how vibrant and dimensional the image can be. A projector with a poor/low contrast will be muddy and flat looking. During dark scenes, it will be harder to differentiate objects, starfields will look medium grey instead of black, etc
There is also on/off contrast. This generally impacts 'fade to black's. Coming from a projector that had decent ANSI contrast, but poor on/off contrast- I was startled by how impressive a good fade to black can be. This is an effect you don't usually find in the theater even since there are always dimmed houselights somewhere for safety purposes.

LCD and LCoS used to be far behind in both kinds of contrast compared to DLP, but that has turned around in the last few years. Now some of the best projectors in on/off are LCoS. LCD has gotten better, but DLP still leads both in ANSI, though I don't think it is by a great margin anymore.

The one big issue with DLP is the way it works. It uses a spinning color wheel to 'paint' each color on the screen- one at a time, but so fast that the eye combines them. For some people, this creates problems from mild (seeing rainbow trails on areas of the screen) to major (headaches from the color separation artifacts).

I would highly suggest seeing examples of DLPs in person because of this factor.
But then, that's just sound advice in general for any and all projectors. These are a good chunk of change and you should be satisfied and know what you are getting into beforehand. 
I would recommend reading up on sites like http://www.projectorreviews.com. Art should have some good general tutorials there addressing the various technologies and considerations of each.

I am looking at a Epson power Lite HD-400 projector. Will this give me a good picture in a semi dark room and does the fact that it is only 16.1 a factor since most of my viewing will be from a dish box?
post #20 of 30

to noki123 - I think your best bet is going to be the Optoma HD20. Just based on popularity alone, this projector is the best for under $1000.

 

It uses DLP technology so the picture is comparitively clear to other LCD 1080p projectors in its price range. Almost everyone who buys this projector is completely satisfied. You could get a 10 foot electric screen and the 1080p projector for under $1200 which has been unheard of until just recently.

 

If not the Optoma, look at the BenQ W1000.

 

Any 1080p projector you buy for around that price is an incredible deal for the money, but you'll be happier if you do a little research on them before you buy.

 

The only time you can really see quality differences is when you compare them side by side. But its hard to do that so pay attention to reviews!

Amit Patel,

 

The best projector you can probably buy for around $2000 based on popularity and reviews is going to be the Epson 8500 UB. Definetly a great projector and people like you constantly agree after watching it.

 

This projector was the first to be THX certified and has a HUGE record breaking contrast ratio which probably benefits an LCD projector more than a DLP projector. (this epson is an LCD projector.)

 

If you want to spend a little more, look at the PT-AE3000U. It was developed by Hollywood and Panasonic and was aimed at producing true and cinematic color. This is the most popular projector in its price range but will cost a bit more than the Epson.

 

Read reviews, they help more than anything. Whichever way you decide to go, you won't be dissapointed!

 tried to think so, but i found it was not as the same in the actual process. As you mentioned, I still have doubts, but really thank you for sharing!

OP for around $500 you can buy an optoma HD65, it was a native res of 720P and can downscale 1080p. It has great reviews from everyone. good luck on your hunt.

post #24 of 30

Thanks for the post. This is very helpful. 

 

post #25 of 30

Today, while searching through threads/ideas for 1080p Projectors, and for company details of projectors, I noted recently most discussions  talk of  720p and 1080p, rather than specifying display resolution.  I own an XGA projector and know its resoultion. I observed WXGA and its resoultions that are greater than XGA.  All of them accept variety of input resolutions which they project only in the projectors native resolution--you can watch them, they are not 720i, 720p or 1080i or 1080p.   Manufacturers and Retailers are now advertising projectors at 720 or HD or 1080, to me as some gimic or euphenisim to hide actual resolution quality of projectors sold as amazing low prices.

 

If I am correct/incorrect, is it possible for you to indicate/list once and for all, for me and everyone else, exactly the display resoltions of 720p vs WXGA vs 1080p, maybe together with VGA and SVGA.  Why buy a "720p" projector vs WXGA.  Currently I sit 9ft from my 8x4 ft projector, connected with component video to my Blu Ray player, and see no screen door effect when showing vaious aspect ratios with my XGA 4:3 aspect projector, Thanks, K.D.

720p=1280x720

1080p=1920x1080

VGA= 640x480

SVGA=800x600

XGA=1024x768

WXGA= depends on who you talk to, fairly close to 720P

Adam,

 

You may want to double check your numbers and correct them.  You are misinforming your readers.  Try a Google search.

Thats what I get for multitasking....Edited my post.  Please next time just correct the info George as it sometimes takes me a while to make it back to a thread to check responses.

Thanks very much to Adam Gregorich and GeorgeAB. You gave me a ball park figure listing and basic understanding about which I can ask local sales representatives and read the manuals, when I get off the net after googling, and go out in the world to see 720P and WXGA (widescreen) products that have inputs I want. I appreciated the fast response.

What projector do you have now? You can't possibly think this is an upgrade from what you have now?

I would not expect much from this projector.

It's probably a throw-away if something goes wrong with it.
