Default Differences between all 45" AQUOS

Hi all,

I've been researching on getting a 42"-45" LCD for only a short period of time. I'm looking for a 1080p w/ PIP. I have my eyes on Sharp Aquos 45" for now. However, I'm getting a little confuse about all the different model numbers that they have. To make the matter worse, different website gives conflicting info. Below is a list of available models. Could someone tell me which is 1080p and what are the major differences between them?
1. 45GX6U
2. 45GD6U
3. 45GD4U
4. 45GD5U
5. 45GD7U

On Sharp's website, all of these 45" are 1080p. Amazon has GX6U & GD5U as 1080i. Cnet has GD4U & GD6U as 1080p.

Also, is there any other good models out there that has 1080p?

Thanks in advance!!

All LCDs are progressive, so Amazon's 1080i is obviously wrong.

These various models probably all use the same LCD panel, but have different features. Side vs. Bottom speakers, external A/V connection box, better sound...

Many makers have RPTV DLP sets ( or LCOS ) that support 1080p/60 now...

I was interested in those models myself because they have native 1920x1080 pixel display panels - the x model has a separate AV box that connects it to the display using a HMDI cable - the others all have internal tuners - some with ATSC some without - but the ones with the internal tuners will not process 1080p input according to one of the reviews on amazon - The GX model will accept 1080p if it is connected directly to the HMDI connector on the display - the last number is the model year so I am told - I guess they are into 2007 by now! - and that the GX is a discontinued model. -here's the page with the info http://www.amazon.com/gp/product/B00...lance&n=172282 - here's the text of the review
Quote:
The issue with these monitors, though, is that Sharp decided that the best you should be able to do with their hardware is to display a 1080i signal. That's fine for today, but the problem is that within a year there should in fact be numerous 1080p sources (in fact, there were several displayed at CES this year) and what's worse is Sharp is somewhat guilty of false advertising as the units are still advertised on Sharp's website as 1080p. In addition, if you're trying to hook up a PC to this the best the tuner will let you display is 1280x1024 resolution - an issue for those with HTPCs. To some extent this is a moot point - the competition is stuck at 1364x768, and it may be hard to tell 1080i from 1080p on a monitor as small as 45" - but there's really no excuse for a monitor that can display 1080p but won't because Sharp wanted to save $100 on hardware.
The good news is that this unit will happily display 1080p resolutions through the monitor's DVI input...but only if you disconnect the tuner and put your own source in. As a workaround its simple, but also requires a separate $250 DVI switcher if you don't want to constantly connect and disconnect. Unfortunately, Sharp has indicated that market research has indicated customers don't want a separate tuner, so all future LCDs will have an integrated one and the GX-series is being phased out. This presents real problems going forward unless they implement a fix, but is why you should grab a GX6U while it's still available. I'd personally prefer an integrated tuner as the AVC (tuner) unit isn't particularly pretty with a card slot in front and doesn't match the rest of my black components, but given the choice between 1080i and 1080p, I'll take the latter every day.
I don't like the one year warranty on these, but problems with these monitors have been significantly less than plasma units.
-I still think this AbesofMaine for $3429 seems like a really good deal - considering orignal MSRP was about twice thatas I recall http://abesofmaine.com/viewproduct.a...&p=writereview

these 2 are the newest 2006 models just released Oct 2005:

LC-45GD5U - black with removable side speakers
LC-45GD7U - Titanium with removable bottom speakers

The other 3 are 2004/2005 models.

I'm not sure why the amazon review made such a big deal over this 1080p thing. I mean Sharp is selling a TV, not a computer monitor here. They have a point about not accepting 1080p/30fps, I suppose, but I doubt that will be used for broadcast as there is not really any advantage over 1080i/30fps, only disavantages from the broadcaster's standpoint.

It seems to me the Sharp panel ability to receive a 1080p/60fps signal via its DVI port should be fine. After spending as much as someone does for this TV another couple hundred bucks for a DVI switcher seems like a small price for the limited number of people who want to use the panel that way. Why penalize everyone else who just want to watch TV?

In any case if you want to use the panel as a 1080p/60fps computer monitor, you have to buy the model that has the external processor and hook up a DVI switcher, or DVDO, between the processor, computer and panel.

what do u mean by all lcd's are progressive? i heard that 1080i could not utilize 1080p. and also, cnet has GD5U and GD7U as 1080i, not 1080p.

What make you choose GX6U over all the other 45" Aquos models?

In terms of price, this is what i found:
http://thecamerapros.com/prodetails.asp?prodid=728

i've seen a few good prices on the GX6U, but i didnt have a chance to look at all their shipping cost yet. another thing you could do to get a good deal is, find the lowest price on the net, go to a local electronic store and see if they'll match it. one of my friend got a dlp from bestbuy because they could match the internet price. the advantage of getting it at local store is that you could personally pick it up if you want and save on shipping, store finance program. another store you might want to try is Sears, they will match your price and give u a 10% discount as well.

There is confusion between the nature of the display itself and the video format the TV will receive. LCD panels are by their design and operation progressive. amazon was pointing out that this TV will not accept a progressive 1080 line signal because they did not want to add the electronics inside to allow either a 1080i or 1080p signal. Two different things.

The GX is the only one that does 1080p from what I can tell {yep - I'm thinking 1920x1080 computer monitor -45" and about 8 feet away}- and you can get a longer (30'?) proprietary cable for $200 more which is a nice HT touch- another thing - it is light <75# without all the speaker and electronics onboard - so a swivel wall mount for a 45" panel sounds attractive for my room - lottsa money though -up to 4 grand maybe- with those extras
MySimon and others gave cheaper prices - but as in the case of 6th Avenue e.g.- the descriptions and availability and even prices on their web page didn't match.- and as I have found on other hi-end HDTV they change the price ^$$ as soon as you call them -I still see prices over $6K for the GX listed- the web price is by no means an actual selling price! --I will certainly check further on availabilty, shipping and reputation before/if I order one - I don't believe most big box BB CC etc will match online (NY,NJ,FL) prices anymore-- in my experience - even from big ones like J&R or Amazon.com - unless they have some open box refurb to sell.

You mentioned that as you could tell, GX6U is the only model that has true 1080p? how do u tell. coz they all say 1080p in their specs. but i was worry because i read somewhere that they actually do not accept 1080p (or 720p, i dont remember the details now) signal, instead, the use 1080i and upconvert it to 1080p.

Yes, all LCDs are progressive... none are refreshed in an interlaced manner.

You may be mixing input formats & display formats... 480i, 480p, 720p, 1080i signal formats for input, but only 1080p/60 for output. All fixed pixel displays must convert all incoming signals to their single native res - it's the only format they can produce.

The OP asked about the differences between specific 45" Sharp LCD HDTV sets - and the factual answer is that none of the sets mentioned will "natively process and display" a 1080p signal connected per manual instructions - to the DVI or HDMI input - here is a quote and link from the AVSforum on the subject
Quote:
You can find a TON of information regarding the Sharp units in the following thread (guaranteed days worth of bathroom reading if you print it):
Regarding the Sharp employees comment that all 3 TVs are EXACTLY identical, well, it's true if you use them only as Sharp documents. However, as the LC-45GX6U is the only unit with a separate AVC box, it is also the only unit where it is possible to make a "direct" connection to the panel. Therefore, it is the only unit with which it is possible to feed a 1080p signal. It's not documented, not supported, and not for the faint of heart. But....it is a difference between the three models. You'll find lots of info on it in the other thread.
personally - I think this 65" one http://www.sharpusa.com/products/Mod...,1572-,00.html spoils it for the rest of us - who don't have $15-20 grand to spend

The difference between model #s is often how the speakers are configured: side or below the screen. The lower #s (4U, 5U) are earlier versions. I have the 6U with the AVC box. Very pleased with it. The most recent version is the 7U.

Discussing 1080p formats without mention of the framerates is confused & confusing... current sets CAN accept all the CURRENT ATSC formats, which include 1080p/24 and 1080p/30. They just can't accept 1080p/60, which isn't an approved transmission standard. The main advantage of a 1080p/60 display is it can display ALL 18 ATSC formats without compromise, preserving the spatial res of 1080i, and the progressive nature & fast framerate of 720p. About the only video signal source that can provide 1080p/60 is a PC, and several VGA inputs can accept that just fine. It's just an issue with HDMI and Component inputs, and next gen chips will fix that soon.
