LG CF181D, New SXRD-projector from LG - Page 19

post #541 of 1266
Quick poll to you guys... This PJ comes with the lens cover. Did any one you actually use that when you are not watching? My ceiling is not too high and I happen to have a cabinet that I can just step up and put it on, but it is still a hassle to do it before and after movies. Is it necessary to cover it up when you are not watching?
post #542 of 1266
I did not use the cover on the ae900 and don't use it on the LG.
post #543 of 1266
I dont use the lens cover and havent on any projector unless I am relocating it.
post #544 of 1266
It's a Len's Protector "Cover", not a Cover to use while watching. It will trap considerable heat between it and the Glass lens, probably result in a fire risk, or in the least damage the Lens.

I don't think in the 8 years I've been on AVS anyone has ever suggested or asked about keeping the Lens Cover on a PJ while in use. Probably because the majority of such Covers are Opaque Plastic, nit clear like the LG.

Anyway, unless your area is rife with Dust, or you smoke excessively....keeping it off only means you might occasionally get up there to Blow dust off it.
post #545 of 1266
Thanks guys. Yes, definitely not putting it on while watching... And seems like I do not even need it to be there when I am not watching either. Great.
post #546 of 1266
I'm wondering if the projector will accept 120 hz native through it's hd15 input? If any of you have a pc have you tried this?

Is there any value in fishing a computer cable from where my AV Rack will be to where the PJ will be? I will be fishing 2 HDMI cable so an extra cable is no big deal. However, I don't own a laptop now but when I will buy one it will most definately have an HDMI output... So I think I might save a few bucks and not buy such cable. Am I missing something with this?
post #548 of 1266
I would fish thru a computer VGA cable.
You never know and like you said the expense is no big deal.

Just have to add my name as a very proud noob owner of the LG 181. Had narrowed down to a couple of PJs but made the choice based on a lot of what has been said here. MM knows I'm working on a DIY screen, but for now I'm broadcasting on a DARK BROWN wall and those who have seen it just say "WOW". No issues, easy setup and spectacular images. Can't wait to get the screen up.

If your "Soon to be had" Laptop's Video Card w/HDMI Out is HDCP compliant, then that will be all you need (HDMI)

If you want backwards compatibility to any PC/CPU device, then run a 15 Pin VGA. Be advised that a decent VGA of 25' is not a inexpensive item ($ 50.00 min. if lucky...) when these days a Very Good HDMI of the same length is just $30.00 (...I have an excellent source @ $1.20 ft. Ver. 1.3b )

Since I seriously doubt you'll get any 2 yr old or more Technology as your Lap'per, the HDMI it should be.

BTW, why so many cords? You should have gotten a Powered 4 to 1 HDMI Switch w/Remote. One such item linked to below is probably substantially less than what you paid for one HDMI if you got a good one.

MUCH better to have just one long HDMI Cord to Rule Them All.

Fellow Advocates,

I have done considerable research into the matter and have found that indeed, Chief Mfg. still sells the older version of the RPA-U (Universal) under a new moniker.

RPA-O (Older Version)

It allows anyone to dismiss the use of the comically ugly Sanus. It accommodates 1- 1/2" diameter Drop Tubing that can conceal both Elec and Vide wiring, and it's extremely Low Profile will make the PJ appear to be suspended at the end of a tube, not "attached to a device that looks uncannily like the Oil Cap on that Crap Well in the Gulf.

Yeah...it's gonna be $25.00 more than the Sanus Mount, but worth a bundle more as far as satisfaction goes.
post #553 of 1266
I would recommend that he runs cables to go into all of the ports on the back of the CF181D.
2 HDMI
1 VGA

Personally, I only use one HDMI going into the CF181D for all 3 HDMI devices. I dont use the second HDMI yet however I am reserving it for maybe the Nokia N8 HDMI based cellphone.

I run my 3 HDMI devices into my Pioneer Receiver and only one HDMI comes out that goes into the pj. I switch between the 3.
However if he is fishing things through and closing things in then it sounds like a lot of work to add things later therefore I would go ahead and fish thru 2 HDMI and 1 VGA.

Just my opinion.

MUCH better to have just one long HDMI Cord to Rule Them All.

Simple: future growth and a horrible DSR530 satellite receiver from Shaw Direct (Canadian Sat provider). It doesn't have HDMI only DVI and the DVI doesn't play well with AV receiver - the HDCP compliance is buggy and there is some sound delay. So component it is and I want to plug it directly so that I keep an input free on my receiver. I just bought a Denon 3311Ci which has 5 inputs in the back and one in the front but with all my AV components they are filling up quickly:
- Dish Network
- Wii
- Xbox 360
- BluRay player
- Legacy DVD player (to play those old regular DVD that the Bluray won't play 'cause they are slightly scratched!)

And BAM the 5 inputs are full on the receiver. I guess I will need a switch soon anyway!

The second HDMI might be an overkill but since I'll be fishing wires... Didn't realize how expensive a RGA cable was these days (50$ ouch! I think I might take my kids and wife to dinner with the 50$ and make sure the laptop I buy is HDCP compliant!)

BTW, none of it is installed and I still have to purchase the PJ and screen. I have my mind set on the LG 100% (thus the post in this thread) but the jury is still out on the screen. I’m reading conflicting advice and am sooooooooooooo confused! But I still have a few weeks to make up my mind.

If my wife wasnt always on my case about where my money goes I would get a custom screen from MississippiMan.
I have a crap screen that she says is fine so I cant do it.
MississippiMan can hook you up with a freakin 150". PM him.

Dude you're crazy! 150"!!! And what makes you think MY wife would go for it???!
post #557 of 1266
Only because you do not already have one.
I convinced my wife wife, "oh honey this 100" will be awesome lets buy it now even though we don't yet have the pj we will just love it".

The rest is history, its small, it sucks, its not custom like MIssissippiMan can make it 148, 145, 143.75. Any custom size you want Dawg.

There is a local guy to me he is coming to do that I wanted to have him do mine at the same time to save on his trandporation cost but my wife aint having it, yet.
post #558 of 1266
Hey Anthony, I am curios as to whether or not you have moved your pj around the house to hit a larger wall to gauge justhow big a screen you may be comfortable with.
post #559 of 1266
No.
I have a room (14.2' X 18.5') where the pj is (crossways) on top of an armoire throwing 14.2 max. Its really at 12.5' throw.
I am thinking about having the pj throw the long distance so I would move the couch and armoire to another wall which would give me an approx 18.5 throw.

With this new layout I could have a really huge screen.

I have not tested it yet.
post #560 of 1266
Got you, that distance would yield a very large image.It may be worth just testing it out on a day when you are up to some furniture moving.It would give you some real world screen size planning numbers and a quick look at potential tradeoffs.

I am sure your current pic is killer and while there is some overall loss of quality as the image size increase the overall impact is well worth it in my world.

Does anyone have and info on when a PC, having VGA and also HDMI, would display better via VGA ?

Or, better colors, brightness, or more resolution choices ?
post #562 of 1266
VGA SUPPORTS up to 1400x1200 res but it'S NOT PROGRESSIVELY SCANNED nor as high res as 1080x1920p
VGA should be considered a convienence connection for those w/no HDMI connectability, NOT a "instead of"
connection
post #563 of 1266
Huh ?

VGA goes to much higher rez than that.

I routinely use it coming out of my OQO for 1920X1080 on my display.
I have another laptop that does 1920X1200 on the same display.

Well AB,

You have to qualify the difference between a "PC" whose Video Card does not have HDMI but only VGA , and one that has both, and you want to determine which might be best. (...Your previous post did that somewhat....) As for PJs, they have to themselves support higher resolutions, or something has to give.

So, the Display. You would seem to me to be asking how a PJ would perform, not a Current model CRT/LCD/ Display on a PC system or a Laptop serving up video only through a VGA output. The OQO units (...you have a Model 2 most likely) have VGA/DVI/HDMI outs so the V card obviously supports all those. Your right about the cord itself to a point. VGA can pass through higher resolutions IF they are available...but it won't support 1080p You now have a 1080p PJ. It does not support any higher resolution than 1080i/p. In that respect the resolution coming through VGA in excess of 1920 x 1080i is moot.

Besides that, VGA output first off does not itself support HDCP, and as such when such a high resolution input is brought into a PJ that has a HDMI in (specifically the 1080p LG CF181D here but to include any 720p PJs as well...) via VGA, the signal received is not going to be processed optimally compared to a true 1920x1080i or p signal. The higher the Resolution, the more it will be compressed, IF the display even has the ability to accept and process it at all..

The LG supports resolution up to 1920x1080 i/p. The other resolutions may not display properly...if at all. All you can do is try, but the inputted signal will be at a disadvantage...not have any advantage.

My answer was predicated on the output coming from a PC card w/no support for HDMI. My experience with using VGA has always been that of seeing 1080i resolution being the highest supporting Res. level available in those cases, and that being dependent upon the PJ. 720p PJs still have to compress 1080i signals.

Basically, if your inputting a 1080p signal, the display has to support that entirely, or itself compress it down (...many 720p PJs can accept and compress 1080p...)
Ditto with any higher interlaced resolution.

The answer to your question, taken into account the disclosed qualifiers, would be that you will not see those higher resolutions displayed on the LG in their native resolution, if at all. If they are viewable, they almost assuredly will not show an improved image, they would be lucky (...as would you...) to see a comparable image.

I'll venture to say I myself did not really qualify my own comments with enough info, (...or enough deep knowledge of the correct vernacular...) but I'm not trying to be, nor can claim proficiency in all things "PC" oriented. I do know that none of the VGA out only Cards I've had supported resolutions beyond what I stated.(1488 x 1200 actually) Your OQO and it's Video processing is obviously a different animal altogether. (...a small one, but mighty in premise...)
post #565 of 1266
Holy ****, do we all need to be this afraid of saying something wrong?
post #566 of 1266
Hi Anthony,

The simple answer is yes, a computer video card can output 1920x1080 image. The problem is for copy protection purposes, 1080P blu ray from a VGA output is not supported. That was built into the spec early on to supposedly protect the video content from being copied directly using a standard VGA output from a computer. There are products on the market that claim to get around this, to disable HDCP and provide blu ray output on VGA but they're probably not legal as such.

For my Vidikron projector, I use VGA 720P for video and feel it's every bit as nice an image as compared to when a video device feeds it 720P. Really, there is no difference, the video res is the same either way, it's just how it's delivered is different. But the needed calibrations for the VGA input and video input may be different, that's something to play with if you decide to run both VGA and video to a projector and alternate sources.

Where in the world are you getting this information from? I have never had any problems using VGA well beyond what you have stated. Are you talking as an input limitation, a specific video card's output limitation, or are you under some sort of [incorrect] impression that VGA and an industry standard video transport cannot do this?

While the original 1987 spec for VGA may define one set of boundaries, they have been greatly, easily, and successfully exceed. Please clarify this seeming misinformation you have presented.

Yes I'm quoting myself...

So at work yesterday I'm with a bunch of co-workers and we are getting ready to have a meeting to review our object model. So my buddy shows up to the meeting room with a PJ and his laptop. I notice in the back of the PJ the HDMI inputs and of course, the VGA input. On our crappy work provided laptops of course have no HDMI output. Who needs a powerful video card to write Java code right?

Anyway I started to laugh and the guys were looking at me funny. I've had hundreds of those meetings with PJ and the answer was in front of all along. Business presentations!!!. I'm sure some avid computer/projector users will use the VGA input but I would bet that 99.99% of the users will be for business presentations and/or simple projections in a business environment. Since the purchasing department in most large companies don't know what they are doing, I'm assuming that all(ok most) PJ's come with VGA inputs... After all some large corporations have too much money and would probably buy way more PJ than they need.

I for one have decided that I won't need the VGA input.

I did in my subsequent following post, acknowledging that my initial remarks did not clearly show I was referring to the input limitations of the Display involved, that being a Video Display that employs both the HDCP standard, as well as the basic inability to accept such resolutions. Or only VGA as may well be the case.

To Wit, it's not the Cord/Connection that is at issue as it's the receiving Display hardware / software limitations.

Funny how a misdirected question and imprecise answer can throw a Thread so off topic. Or maybe not so much so.

It's this way....if you buy a 1080p projector, and want to display a PC's output on it, you will be limited to that PJ's input specifications. and the VGA image "probably" won't be any better, if as good as any actual 1080p content. That is what I was trying to convey.

Waterfowl simply said the same thing more concisely...and accurately
post #570 of 1266
I only asked my original question for zbroke to convince him to run VGA.

He has already decided to not use VGA therefore my question and answers will serve no one now.
