Samsung wiselink question

Does anyone know how to make the pictures on my USB flash drive full screen when using WiseLink? I can zoom to fullscreen, but would like to make that the default size when viewing pictures. Right now they only take up the center of the screen, about 2/3 of the available screen. I have the DLP HL-S5086.

They should appear full screen without any additional effort from you - assuming, of course, that your image is 16:9. If it's not 16:9, then there's no way to make it full screen without either cropping or distorting the image.

I am using a 6MP Canon A700 camera and pictures taken at full resolution are displayed with black bars on the sides. Only pictures that I have taken using the 16:9 (not full resolution of camera but still quite good) mode fill the screen.

I have a 4MP Canon A80 with pics taken at full resolution (higher res than the TV's native resolution). But my pictures have black bars on all four sides. I'd be happy if they only had bars on the sides. What resolutions should I convert the images to for best results?

The resolution of your display is 1920x1080. I've put a 1920x1080 image in and it fills the whole screen on my 6188.

Your A80 shoots at 4:3. It's strange that you're getting black bars on all four sides. One would think that it would just letterbox. Perhaps they're shrinking things a bit to hide the pincushioning? I'll try a large 4:3 image on my set when I get home tonight and I'll let you know what I see.

I wish it was 1920x1080, but I have the 720p model, the HLS5086, not the 5087. So I'm shooting for 1280x720? My camera defaults to 2272x1704 at the highest setting. Should I just make the image a multiple of 720p, like 1920x1440 (720 wide times two)? Would that at least fill the height of the screen, leaving bars on the sides?

I'm sorry that I can't give you defniitive answer tonight, as I promised. My wife is watching the TV...

Before I lost control, I did try downloading the following test image (in 1920x1080), putting it on a memory card, and displaying it using wiselink:

http://www.tigerdave.com/test_patterns.htm

I tried the 1920x1080 pattern in wiselink on my 6188 with overscan turned off in the service menu. Good news: The image fills the whole screen. Bad news: There's still overscan and the set utterly fails to resolve the fine lines in the pattern. Worse news: There appear to be small convergence errors. How can there be convergence errors in a single chip set?

I also tried burning the images onto a CD and displaying them through my Samsung DVD-HD960 over HDMI. In this case, the image did not fill the scrren - there were black boxes on either side. Perhaps the player is expecting that the set has overscan enabled?

Hmmm... My wife may have surrendered control of the TV. More in a bit...

OK - some more tests:

6 MP 3:2 format image in landscape orientation from a Canon 20D: Uses the entire height of the screen, but doesn't fill the width. This seems to be the correct behavior.

6 MP 3:2 format image in portraint orientation from a Canon D60: Uses the entire height of the screen, but doesn't fill the width. This seems to be the correct behavior.

8MP 3:2 format image in landscape orientation from a Canon 20D: Uses the entire height of the screen, but doesn't fill the width. This seems to be the correct behavior except that the image is downsampled very crudely and has lots of jagged edges.

7MP 4:3 format image in landscape orientation from a Canon SD500: Uses the entire height of the screen, but doesn't fill the width. This seems to be the correct behavior except that the image is downsampled very crudely and has lots of jagged edges.

7MP 4:3 format image in portrait orientation from a Canon SD500: Uses the entire height of the screen, but doesn't fill the width. This seems to be the correct behavior except that the image is downsampled very crudely and has lots of jagged edges.

Summary: Aside from a very bad downsampling algorithm, the set seems to be doing the right thing. I do not get horizontal bars.

Thanks for the info. Can you tell me the resolutions of the pictures you used to test (in pixels wide x pixels high)?

I guess I'll just have to play around with different resolutions to see what fits best. Maybe a Samsung customer service rep would have a suggestion.

Thanks,
Brian

Those test images were very helpful, thanks. Several test images later, I've found that the built in scaling the TV does for photos can change drastically, depending on the resolution of the picture you viewed before it. If I viewed one picture, it would scale correctly, and switch to the next picture (same picture at a different resolution), it would scale it with black bars on all sides. If I went back to the first photo, it would be zoomed in significantly. The code they used for scaling is not bug free it seems.

At any rate, it appears that if I use resolutions at about 1080 wide work well, so I will just pre-process the photos to 1440x1080 (keep the aspect ratio of the original 4mp pictures), and the pictures look stunningly clear on the TV.

Hello, this is my first post to this great forum and I hope you folks can help.

I was very close to purchasing the 50" Samsung HL-S5088 today but my final test was to view some high resolution JPGs using the WiseLink USB port. I expected the 1080P resolution to do a pretty good job of displaying the images but was very disappointed. The images are from a Canon 20D with about 3k by 2k pixels and a variety of high and low contrast, finely detailed images.

In searching the forum I see the the algorithm for scaling the images may not be very solid. What I was seeing were images that were displayed at 1/2 the size they should have been or in some cases they were scaled well but the resolution was very poor. The edges in the image were blocky with lots of false contouring in smooth areas of the images. This was at our local Tweeter store and the sales guy was very surprised also.

We took the same usb drive to several other HDTVs and in general the results were more what I would expect. The best by far was on a 720P plasma unit.

So, my question is should I expect to see much better results if I play the images from a DVD player as full resolution JPGs copied to a disk. Assuming the player is capable of reading JPG files? Viewing image displays is an important application for my use of the TV and I want the images to look really good.

I don't care so much about the WiseLink path, it was just a convient way to try the demo.

Any feedback is appreciated.

Thanks,

Thanks,

I can confirm your findings. I took in a couple shots on a USB stick, they were 1600x1200 JPGs. Well the LN-S4096D (40" LCD) did not rescale very well. It simply dropped half the pixels in both directions and to make it 800x600. When zoomed by 2X, 4X the set merely displayed the downscaled image with bigger pixels. Yuck.

Next time, I'm going to take TigerDave's test patterns and try again to see if it's a general issue with any picture that exceeds the screen resolution. If yes, I would suggest calling up Samsung and register complain to get a proper JPG scaler firmware.

I guess this means we will all have to rescale digital photos to something that does not exceed 1920 x 1080 to get proper results.

Why on earth would they use pixel resizing??? Bilinear and Bicubic is not hard to do ...

Stavr0,

Thanks for the reply on the WiseLink JPEG scaling. I did purchase the TV the other day so I could get some hands-on experience and so far I am please with most aspects of the unit except for the WiseLink scaling. I is very crude compared to the other high-tech features.

I tried a few experiments and did find that if I rescaled the JPEGs in a photo editor to get to an image size of ?? x 1080 where ?? is whatever width it takes to make the line count = 1080 I got very good results. It appeard the TV just displays what it gets and does no scaling.

I guess the USB port will only be a convient way to get a quick look at some images but not a high quality slide show. I started looking for an HD-DVD player that would handle native JPEGs files but that does not seem to ba a high priority for their designers either. The best way may be to use a good HD-DVD video authoring program to build actual HD slide shows. It's more work but the results may be the best.

Regards,

There is an excellent image processing software, that is free and open source, therefore available on any PC (Win/Mac/Linux) called IMAGEMAGICK .

It's not hard to write a Batch/Script to process a whole bunch of files to rescale to the target screen extents ( 1920x1080 or 1280x720 )

The -resize option does the right thing by default: enlarge or reduce the picture so it fits but does not exceed the specified dimensions. There are also options to specify 'leave smaller pictures alone' and so on. And for a bonus, the -filter option has no less than FIFTEEN resize algorithms to choose from.

Code:
convert  IMG_7654.JPG  -quality 100 -filter lanczos -resize 1920x1080 slide001.jpg
This produces a near-lossless JPG that would be as big as a 1080p set would show.

There's also the option of using a laptop connected to the PC in ...

Thanks so much for the pointer to IMAGEMAGICK. It looks like a very powerful tool and I believe it will be useful for the HDTV resizing as well as many other tasks.

Do you by any chance have knowledge of a good open source software package that is capable of authoring HD DVD slideshows ?

Thanks again.

Just to add to this discussion.. I was experimenting today.

What I found is, despite having a 720p tv, scaling all my images to 1080p resolution resulting in the best displayed image. Correct aspect of 3:2 both vertical and horizontal.

I -think- they just have one scaling package for all the TVs.. when I did 1280x720 I was getting it scaled too small (black bars all 4 sides) but 1920x1080 was good. 800x600 and some others scaled well, but this resolution seemed to produce the best image quality.

I will keep experimenting and pass back anything else I find. Good luck!

Hi,
This is my first post in here. So please bear with me.
I recently got Samsung LNT4661F model TV and was playing with all features and found this WiseLink.
I connected iPod to the TV and was able to view photographs at full screen mode but when I tried to play songs, i found 2 issues with it.
first, the song names are displayed as short names so no way we could figure out what song is what.
Second, when you let TV play songs, after 2 min or 5 min (this is max setting for screen saver) screen saver comes and all of a sudden that song becomes like a continuous awkward beep sound (i felt like tv got damaged or something)
I had to switch of TV off suddenly on both occassions as a quick action.

I tried to take off screen saver setting off but there is not any.

Has anyone seen this issue before? please let me know. I know i have different ways to connect iPod to the TV but just wondering why it would not work.

Thanks for you help.

I got a USB Thumb Drive at Fries, popped it into my Windows XP system, copied some JPG images to it (both too the root of the drive and into named folders), and brought it over to my new Samsung LNT4665F TV to try out the Wiselink.

The first time, it just said "Check up USB device" or something. I unplugged it, took it back to the XP computer, verified everything was okay, took it back to the TV, and now it brings up the "Photo, Music, Setup" menu fine, but when I press ENTER with Photo selected, I just get "There is no file or folder in your device".

Huh?

Obviously there are both files and folders in my device. XP sees it fine.

Can anyone help me? What could possibly be going wrong here? My first attempt at playing with Wiselink has been a complete failure... help!

Having the same problem here. Can't get Wiselink to recognize my flash drive. Called Samsung and they informed me that I needed a Mass storage Device. After a little research, I determined that the flash drive IS a Mass stroage device.

Can anyone please provide the name of a specific device that has worked for them? It's a little frustrating to have this one item not work when the overall quality of the SAmsung TV is great. Thanks in advance.

I'm having the same problems with the Wiselink. It worked i think the first time I got the tv, but now doesn't work. I tried 3 different brands of USB drivers (sandisk, kingston, & sony) but none work. I made sure I formatted them and had no secondary software on it. One thing I did notice is that the USB device does not seem to be getting any power as the light on the back turns on at first then not again. That might be the problem. Anyone know a fix for it?
