Though reading through the directions, it appears as if it will. In the PC connection section of the manual, there are specific timings for a 1360x768 resolution via DVI/HDMI, and it also says that 1:1 mapping is only available for PC or HDMI connections. I hope this works!



WHAT IS 1:1 mapping?
post #62 of 3882
1:1 mapping means the TV displays the signal exactly the way it was sent. So, if you are outputting from a computer, and output say, a 640x480 resolution, you'd end up with a 640x480 image in the center of the screen. This comes into play when outputting from, say a HTPC. The actual screen resolution is 1366x768. Unfortunately, a video card cant output this resolution- it can only output 1360x768. So, if the TV cannot do 1:1 mapping, and you send it a 1360x768 image, it will overscan your image by 6 pixels, thus slightly blurring your image.

The good news about this panel, is it appears to properly 1:1 map a 1360x768 signal input via DVI->HDMI. I can actually count 3 columns of black pixels on the left and right side of the image- so it isn't overscanning to 1366x768.

Somewhere there was a test image to see if you are doing 1:1 mapping- anyone remember where this is?

That was the one, and it is rendering pixel PERFECT via DVI->HDMI @ 1360x768 in 16:9 mode, as well as via VGA. I also get a perfect image via both DVI->HDMI and VGA at 1024x768 in 4:3 mode.

I think this one is a keeper!

sounds like these are trouble. no PIP, problems with inputs, etc.

i guess it is on to the next manufacturer!

That's too bad, because you are going to miss out on a great set. I have the 32" model (LN-T3253H), and it's incredible so far. Great blacks, great color, great performance and sharp images. I would at least go to a store and take a look at it for yourself if you haven't already.

Could someone post some pictures of the 42 series? All of the pictures so far are of the 53 series. I am looking at the 42 series and would like to see one. I live far away from any electronics store so it is hard for me to see these things in person so this is the next best thing.

Here's the largest photo I can find on the internet of the LN-T4042H. Click on the thumbnail photo:



I don't know if the frame is glossy black or flat black in real life. Samsung's official photos of the LN-T4053H made the frames look flat black, but in reality they are glossy black.

That was the best picture I could find as well. That is why I was hoping that someone who has one could post a few pictures, to help clear that up.
post #70 of 3882
I have it, and the frame is glossy black, with a small chrome strip across the bottom.
This tv is not like other flat panels, especially those from Samsung.
They really have got the sound 100 times better. Very good, even the surround sound settings sound good. CD quality. Even the preset sounds are good. Does not sound hollow.
Picture is awesome.

go to circuit city or best buy for photos.

I just purchased a LN-T4042H. Looks great, only problem I have is when I use my xbox 360 with 720p running through component sometimes i get a strange line running across the screen. I thought it was the tv so I took it back and exchanged it, now i'm having the same problem. I thought this could be some sort of interference, but I'm not entirely sure.

what model exactly do you own? the 42H or 53H. Also what size?

edit: Do you use an option called "Just Scan" to enable 1:1 pixel mapping

I'm having the same issue with my HD DVR and my DVD (both connected through HDMI). The line appears for a second and is 5 inches from the bottom. I saw this line 3 or 4 times in the last 10 days. Anyone have any idea why this happens?

dchris2-

I have the 4053H (40").

And no, I dont enable "Just Scan" for 1:1 mapping. Just Scan is only for 1080i/720p resolutions input (I can do "Just Scan" if I send a 1280x720 resolution). But, Just Scan doesnt appear to be 1:1- it scales the 1280x720 res to fill the whole screen.

When you connect to the 4053H via VGA or DVI->HDMI, and send a 1360x768 resolution signal, and you set the mode to "16:9", it assumes the signal is coming from a computer, and does no scaling on it. If you are using VGA, it gives you some extra "PC" options that aren't available when using DVI->HDMI, however those options look like they are to try to get the analog VGA signal as good as the digial DVI->HDMI signal. When using DVI->HDMI, you dont have the PC options, but you can still set the "Home Theater PC" option (which increases contrast, but somewhat harshly), but more important, you can set the "HDMI black level" to "Low" which yields a very nice picture.

As for how I know it is 1:1 mapping- I have done several tests. The first is just the text- it is crisp, and clear- not fuzzy like on sets where overscanning is occuring. My thought at the time was "either this is 1:1 mapping, or this TV has one hell of a scaler!" because it looks great. The second thing I looked at was the test pattern. I set it to tile on my desktop, and there was no cycling/phaseing of the image- it was uniform across the display, and all of the lines were crisp. Next, I pulled out a magnifying glass, and looked at the edge of the screen. I can CLEARLY see 3 columns of pixels that are black on the left and right edge. Since the native resolution of the display is 1366x768, and I am sending a 1360x768 signal, the 3 columns on each side mean that it is taking my 1360x768 signal and centering it in the screen, and not scaling it (3+1360+3=1366).

So the verdict is- if you want a 720p panel that will do 1:1 mapping from your computer using DVI->HDMI, the 4053H will fit the bill.

I'd be happy to take some pictures of the screen with a computer image on it tonight and post them, if you'd like.

Same issue I'm having. I see it more often than 3 or 4 times though. Sometimes 3 or 4 times within a two hour period.
post #76 of 3882
What do you guys think of this price?

Circuity City: LN-T2653H for $719. (I'm too new to post a link, it won't let me till I have 5 posts )

Also:
Olivea 27inch for $499.

I'm looking for a second TV that will be primarily used for PS3 (or Xbox Elite, haven't decided). Maybe used for DVD's, but I all ready own a 42inch Sony Plasma that is my primary TV. I just want an awesome picture for my games and that Samsung maybe overkill for my needs, but it had a gaming mode and 2 HDMI's.

Plus that price looked really good. The 23inch is $640 at Office Depot, I'd just get BB to match. Circuit City's replacement plans are stupid expensive. $189 for 5 years when BB is $99 for four years. CC would have to come down a bit in their price for me to buy there. Wonder if I even need a plan (I'll search for that topic).

You haven't had any problems that have been mentioned?

I want a 40" Tv and am mving away from Sharp. I thought this was it until I read all th einput problems. I could care less about PQ if Inputs don't work. I am going thru that now with Sharp.

Also, this TV doesn't really have true PIP.
post #78 of 3882
Input problems???
post #79 of 3882
Guppie58,

It shocks me to find that Circuit City is significantly cheaper on the LN-T2653H than any other online retailer I cound find! Get that quick before they change their mind!

post #81 of 3882
CC just changed it back to $999. It was $718 for three days. I guess I waited too long. . It was probable overkill for me anyways. I'd be more than happy with a 23. Now, olevia or samsung....

thanks for the clarification. Actually I am living in the UK and I think here they are selling the 53H as R87.

That doesn't mean I don't want to see pictures
post #83 of 3882
For those who have the problem off the strange line running across the screen, what model exactly do you own? the 42H or 53H.

Because I am going to buy the 53H to play Xbox 360 on it.

Thanks

42H

Is anyone with a 53H having this issue?

Nice work. I tried to get my local BB to match that price and they refused. Did you do anything special to get them to match the Office Depot Price?

This doesn't sound good, I was going to get a LN-T3242H. I hope that this is not a common issue with the 42 series. The LN-T3253H is $150 more on hideflifestyle and I don't feel that the slightly better specs are worth the jump in price. So could someone contact Samsung about this?

I printed up the page from Amazon that showed the price and the fact that it was being sold by Office Depot. The BB sales guy took this sheet back to his manager and a few minutes later came back saying he would match it ... he then started trying to sell me on some other things to go with it. As I said, I did buy Component Video Cables for 60 bucks at BB as well. I returned those today however and got the non-Monster version for half the price at Wal-Mart. I'll be using those for my DVD player.

The TV is really amazing thus far. Very clean look. All I used for HD last night was some old rabbit ears and I was able to watch 6 or 7 OTA channels. Great clarity, color depth and plenty of video options. The sound was really nice too. It was interesting to hear the difference in sound when switching from Digital Cable to OTA HD Broadcast ... I could actually tell the difference. More dynamic in HD.

I had originally planned to use this 4053 for a couple of years and then move it into my bedroom and get a 46 or larger to replace it. After getting it home, it seems to be more than enough for my space. I think anything larger would look out of place. It's funny how looking at it in the stores next to the 46 and 50 inch TVs make it look so small, but when it's on it's own it is perfect.

Before anybody starts repackaging their TV for return, I have to ask is the streak some of you are experiencing another word for "tearing?" Some Xbox 360 games experience tearing -- i.e. a horizontal line across the screen showing the image losing vsync. I have had my 360 on several HD and non-HD sets and gotten tearing. If this is the case, than it is normal and an issue with how the game was created for the 360 and not with the TV. If it is something else, well then I have no clue.

Have a good one and I hope this issue is merely tearing as I have ordered an 53H for myself. So crossfingers!
post #89 of 3882
It seem like the problem is with the 42H. Anyone can confirm?

Yeah I think Jedi Master hit the nail on that one.... When does the streak occur? Does it occur when you turn really fast?

Out of all the people that have the LNT-3253H, what are your impressions so far? Thinking about getting this for my 360... I have the LNT-4066f and really like it but 1080p really doesnt seeem to be that huge of a factor for me. I don't even think I can tell the difference between it and the old sharp I had that was 720p. Might just save myself a grand and go with the 720 until much better stuff comes out like LED then switch this to the bedroom...

I need to know if there is just scan on HDMI, and looks like vga does 1:1. Anyone using thier xbox with vga? TIA
