Samsung 720p Owner's Thread --- HLTXX75S DLP Models - Page 10

I noticed the same thing for the first week I had it in both HDMI and the DVD inputs (component). After making many changes to different settings I noticed it had gone away. I'm not sure what killed it, but it appears to be something to do with one of the auto settings that makes it switch back and forth based on the amount of black in the scene. It does not appear to be a defect, just annoying.

I have since found that in order to adjust for overscan by renaming HDMI1 to PC the input source must be 720p, not 1080i.

Are you sure? I have my HD STB set to output both 720p and 1080i signals thereby letting the TV select which is the more appropriate and avoiding up/down sampling of the signal. As such, I have seen no overscan problems since setting the HDMI label to PC.

in standard mode (with DNiE and Dynamic Contrast disabled) there are no problems.

my guess is that it's the dynamic contrast that's causing the issues.

I have a satellite set top box that unfortunately does not auto switch from 1080 to 720. If I set it to 1080, the image will overscan no matter what I rename the source to. However, as soon as I switched the box to output 720p, the overscan is gone. For those out there who see no change when they rename to PC, this is one possible solution.
p.s. I am also using a cable to convert from dvi to hdmi, so I'm not sure if this has anything to do with it as well.

I would love to buy this TV since it's just the right price for me now.
How does it perform with 480i content (playstation 2, xbox, etc)? Any lag? I play a lot of fighters and shooters (twitch action games), and I cannot stand lag.

I have a question about the PC labeling thingy. I will label it as PC on HDMI 1 to get rid of overscan for xbox 360, but whenever I do that, it reverts to its standard PC aspect (which has about 1 inch black borders all the way around the picture). I can eliminate this by hitting "Aspect" and using the manual controls, but that gets very annoying every time... does your adjustment "stick" if you expand the picture manually? Thanks

I think the 480i issue is that it looks not-so-good (I have a gamecube on my hlr series set) but I use component cables on my original series xbox. You might buy from a place with a liberal return policy and try for yourself.

480i looks fine for TV stuff, most of the time, but for gaming... yeah, it's not so good. It's quite blurry when in motion, but when on a still screen, it's quite sharp.

Maybe a video processor would help...

You can notice the blurring pretty severely on a fighting game which isn't 480p capable.

It's cool to see that there are fairly easy ways to deal with overscan, although I'm mainly concerned with it in relation to PC inputs. I have a 60" 1080p 2006 Sammy, the one that requires a tweak of overscan after every reboot. Also, it suffers from wobulation. Are 720p's free from wobulation? I am interested in one of these for a second room in my new apartment...looking at the 50" going for under $1000 bucks at Best Buy...a little more with 4 year warranty. I'm kind of feeling spontaneous with this purchase, so I haven't looked at too much other stuff, but the price is right for a TV I might use for PC gaming, or PS2/Gamecube/xbox gaming. I'm keeping my new consoles on the 1080p box. Do these suffer from much overscan over the PC input? And can I get a crisp 1:1 at 1280x720 over PC input? The wobulation and overscan in my 1080p is so nasty compared to the sharpness of my previous 720p 50" display (although it wasn't much better with the overscan).

Also, I have been fortunate that as a gamer I've never experienced any lag on my old 2003 and 2006 models...how could things get more laggy as tech improves? Do my optical connections just not see it? I'm generally sensitive to it, as well as flickering of CRT monitors at a low refresh.

Sorry this is so scattered....it's been a long day and I am quite tired.

my 4675 will not do this. It overscans hdmi1 no matter what the label is. also tried forcing my cable box to do 720p or 1080i and no matter what it was set at it would still overscan with hdmi1 labeled as PC. I wish samsung had just put the option to turn overscan off like they did on the xx76 series.

also with my 4675 the hdmi inputs the picture is about an inch too low. L/R seem to be lined up fine. All of my things hooked up via component is centered great. I went into the service menu and moved the picture up but once i did that now my components were an inch high and the hdmi was centered. I was under the impression that you could adjust this for specific inputs but i guess not. Because no matter what input i was on when i went into the service menu it would move the picture for all of them.

*edit*
I have a motorola HD DVR box... I just went into the settings on it, on a total hunch. Set it to 720p and it still overscanned. Right below that setting is advanced HDMI settings. Went into that and switched it to DVI instead of HDMI... The overscan went away and i have about a half inch black bar all the way around. Favoring the bottom a more than the top but not nearly as bad as went its overscanning. I think i'm going to run it like this for a while. I was watching ESPN2 HD and couldn't believe how much of the screen is getting cut off due to overscanning. Anyways once i got this figured out. I switched the box back to 1080i manually and the TV went back into overscanning. So if you have a motorola HD box and don't want the overscanning. Set the label to pc and change it to DVI in the HD Box. If it doesn't bother you enjoy!

*edit again*
I went into the TV settings and with my cable box setup like this now my Sharpness Color and Tint are greyed out and i can't adjust them. But now i can go into Size and i have Wide TV, Wide PC, and 4:3. Wide PC has the black bars around the outside edge. Wide TV pushes the screen out to where my guess would be there's only about 1-2% of overscan. This i can live with. Luckily i don't need to adjust any of the things that are grey'd out its mainly the brightness and contrast that i need to adjust. If you ask me this tv is kind of screwy but oh well i'm still happy with the PQ it has.

Much thanks, Jim!

Thanks for the detailed post vdub85.

I too have the Motorola box and it took going into the service menu (only accessable when the box is powered off by hitting the menu button) to get to advanced HDMI settings and change it to DVI output. My Samsung then was able to recognize it as a PC input and change to the correct aspect ratio with little or no overscan.

My only problem is this:

In HDMI-PC mode, with the box outputting 720p, the picture looks less crisp and vibrant than it did when it was overscanning at 1080i. I watch alot of sports and have 20/20 vision and am pretty convinced that this is indeed the case.

Any thoughts on this? Could the signal somehow be downgraded by the TV when you are tricking it by telling it a PC is the source?

THoughts?

Has nothing to do with the signal, it's the design of the TV.

It's a 720p TV which does not show all 1280x720 pixels at once. (I remember reading something on this website about RPTVs and this is the nature of them...)

When you go into HDMI PC mode, to "fit" all the 1280x720 pixels on the screen, the image is actually resized a bit. You can easily tell this if you connect a PC outputting a 1280x720 image and use Wide PC mode. It's mapping is not 1:1

HOWEVER, when you use "Wide TV" with a 1280x720 image, the image is 1:1 but with some slight overscan. The missing pixels don't show up on the projection screen.

As far as the "screen" itself goes, it's more along the lines of showing 1152x648 pixels than 1280x720. (So in wide PC, it resizes the 1280x720 image to 1152x648 and displays it.. in Wide TV, it zooms in on the 1280x720 image and shows 1152x648 of it...)

Just wanted to add onto this thread, instead of editing my post 'cuz some may have read it since I posted it way earlier today, that I had always been wanting to tweak my PC display on this thing to the best it can look.

I have an nVidia 7950GT connected to this TV through DVI->HDMI

If you want the best display you can possibly get using this TV and 1:1 mapping, set the display in Windows to 1280x720 using 720P.

After you've done this, go to the nVidia Control Panel and go to Resize Desktop. Flip your TV from "Wide PC" to "Wide TV" and then shrink the vertical and horizontal about 6 clicks each.

You should end up with a resolution of 1176x664.

Click OK then Apply.

You should end up with an excellent display.

I hoook my xbox 360 up through the hdmi port. I bought a new surround sound system. How do I get sound to work through the optical output

The optical output does not pass sound through for the HDMI inputs. You will have to run the HDMI cable from the xbox to the TV and using the xbox "dongle", pass the optical audio directly from the xbox to your A/V receiver.

Sooooo stupid!

Is the 46" model, or any model of this DLP series good with xbox 360 and PS3? Will I get ghosting like flat panel LCDs? Im contemplating this and a sony RPLCD.

Our PVR does not have a screen saver or dim down when you pause a show. Do we need to worry about damaging anything when we pause a show?

So I had a house guess come and leave my tv on all day on... espn 2 hd. Can anyone guess what happened?

Absolutely nothing? I leave my TV on all the time on different channels.

If this is a "burn-in" post, just FYI, DLPs don't burn-in... So I really don't know what your post could be about, unless your bulb exploded while you were away...

Also to the guy who asked about 360 and PS3, these TVs are fine for them. I have a 360, PS2, Wii, and other junk hooked up to my TV. DLPs are great for gaming... go ahead and rock out.

u both fell asleep cuddling?
The poster above me is spot on. Nothing should have happened..

Hey guys, I have a question. Do your TV settings "stick"? It seems like about 50% of the time that I remember i actually check it, my "cable" input reverts back to dynamic settings. In addition, if i switch it back to movie, the settings are all at their default, anyone else hit this trouble? Thanks in advance!

You need to get your TV out of "Shop" mode :x

Its a great tv to have with a 360 or PS3. No ghosting at all. I noticed a bit of lag a couple times but setting it to game mode took care of that problem.

After reading here...

http://www.hdtvsolutions.com/Samsung-HL-T5075S.htm

the response time is 16ms..I was worried my 360 wouldn't look good on the t5075s...but you guys say shooters look good?

Also...how do you watch HD DVD? HDMI to tv and red and white rca to a reciever.

Last thing...all the talk of overscan has me worried of loosing % of picture...is this also a problem on LCD? This would be my 1st hdtv.

i guess this is last...if i wait awhile to upgade my cable...how does reg def tv look? I think someone posted 480i ps2 looked good cept words?

Thanks

There may be a thread on this but...why did you guys go DLP and not LCD?

There is some overscan, but it seems like the TV stations compensate for this. For a while, I switched my HDMI 1 input to PC and it actually seemed odd looking. The bottom scrollers on channels seemed like they were too high on the screen since I'm used to them being on the bottom. Plus the black border around the picture bothered me. I switched it back to "normal" and the overscan isn't noticeable.

Standard def looks like crap on a lot of channels.

I have an hlt5675s and play Halo 3 on my 360 all the time and everything works perfect. No lag or ghosting. It feels like I'm playing on a PC CRT.

I picked this model because of the price. $1099 for a 56" DLP...hell yeah

CC is having a black friday sale of 800 for this set.

I've been looking for a HDTV...is this the deal I should finally jump on?

This is a similar price to the BB deal w/the xbox from earlier this year.

I'd say go for it. And I wouldnt worry about buying a PP either. The set comes with a 15 month parts and in-home warranty from Samsung.

If you don't really care about it not being 1080p, then go for it.

The only problem with this set, as per most of the posts on this board, is the overscan. This is tweakable and does not bother me at all. I leave the overscan for network shows (the office, heros) and change it to 720p to get rid of it for sporting events (the overscan trims some of the picture out)

ENJOY!
