My only thought is the PC is changing the output when full screen is selected. What resolution is the laptop set for right now?

HDTV resolutions are 1920x1080i and 1280x720p/60Hz. If your PC won't do either of those, your HDTV may be not compatible.

I Tried doin that too.. The thing is all works fine except the full screen. I tried playing with VLC by hiding task bar and everthing except the top bar instead of making it full screen.. That works fine. It looks almost like full screen. But i donno why making it full screen gives No sync error. That too every 5 mins once.

Thanks

Hi rajamsa, I've read you in some other forums posting the same issue and finally I decided to write here. I have the same problem than you (and jozkopuk as well): "No sync" blackouts during fullscreen playback only, just as you described. I guess your graphics card is an ati. Don't know why but I think that is the root of the problem. Maybe if we share information about configurations or any progress we could find a solution or at least discard possible causes.

My tv, is a sony bravia model kdl-32p3500, which is almost the same as yours. Ive connected a laptop through vga cable (dsub 15 pins). The tv's config is just right out of the box. The laptop's video card is an ati radeon xpress 200 with latest Catalyst drivers installed. Everything is fine except for the fullscreen playback. Ive tried reproducing hd content (mkv) only with wmp, vlc and kmplayer.
The CCC detects a standard monitor attached to the laptop (not a tv or sony device). The resolution must be 1280x768 (or less) in order to get signal. Ive done some tests cloning the desktop but no extending. Also, I have been modifing some CCC options with no luck.

any idea or progress rajamsa?

I will do some other tests tonight, if I have time.

PD: I forgot to mention that the blackouts were in my case 5-10 sec delayed at the beginning, and then I added horizontal and vertical sync in the display properties (CCC) getting a delay about 5 minutes like you. does this have any sense? Thanks for the attention anyway and regards from Spain.

I am experiencing the exact same problem!

@torete43

Oh and btw I have the same Bravia model as you, but I have on the other hand an graphics card from Nvidia in my laptop. So the problem is not only because of an Ati card.

Ok, this is a good start. Did you try using HDMI or components instead VGA? I don't have the proper connectors.
So it doesn't matter what video card are we using... I would like to believe that it isn't a TV problem... maybe because of the vga connection. I have a multimedia jukebox connected via components or even rca, and everything is fine. So I think there must be an issue with the vga resolution, synchronization or whatever, regardless of the graphics card. Im downloading mkv content, so I will do some new tests on these days. I'll keep you update if there's something new.

Anyone lucky with similar Bravia models?

Ive just realized that the desktop is not well fitted into the tv screen, I mean, the first letters of the most left icons are not visible. Besides that, some flashing pink points appear on the most right side of the tv screen if you look closer. Anyone with similar issue?
This seems to be something related with the vga sync, any idea?

This is so f*c king weird... everything is fine except for the fullscreen video playback.

Well, since the moment this problem occurred i tried to look at the laptop for an other possiblity to connect my laptop to the Bravia. I found out my laptop also has an S-video output.
So I bought an S-video to SCART connection cable, once everything plugged in and it works like a charm. I watched a movie on full screen and it gave no problems.
But here comes the big downside from S-video everything looks horrible, and there is no way to fix that. So while watching an xvid movie the quality dramatically decreased. So I won't recommend this method for connecting the laptop to the LCD at all.

Anyway, that's all what I tried for now.

And I hope you find this information useful.

Of course is usefull. Ive been tempted to buy a s-video cable but suspected that it wouldn't work in HD. The only way to get HD quality in our Bravia model is using VGA (analog) or HDMI (digital)... and maybe components? not sure...

Oh really? A thought went up my mind today about these things. So I am gonna return my S-video to SCART connection cable and I'm trying to get a S-video to component in return, since SCART is old fashion. That's probably why it gives the awful resolution on the TV. But now you're saying, S-video to component will not work? You sure about that? Since they do exist. Well I will do my best with this and I will surely keep you updated.

EDIT: I also did tried to connect my laptop by using the VGA cable on a other LCD TV a pretty old one even, but it had an PC output. So i did give it a try, and you probably already gonna know what i am gonna say now. Yeah it fully worked no problems whatsoever with watching a movie on full screen. So this Bravia model has some problems with a simple VGA cable. Why? Beats me.

I think so...The problem of s-video to components is not the tv input (components) but the pc output (s-video). I think that s-video is not suitable for hd signals (not enough bandwidth) regardless of the system the signal is converted to (components, composite video or whatever...). Someone correct me if Im wrong.
Anyway, Im a little bit confused cause the s-video of my laptop is 7-pin not 4-pin as I used to know. Maybe it is possible a higher res in the 7-pin specification? So, im gonna look for a s-video to components cable to do the test. I know I have one somewhere.

This guys of Sony.... Im a fan of the brand, I have to admit, and Im very happy with the overall performance for such a low price. But a mistake like this... so fool....

Default Good news!

I tried s-video (7pin) to components but no luck. My video card doesn't provide components through that port. Anyway... there are good news.

After doing a lot of tests even modifing the internal sync frequencies of the vcard, I have just come with a practical solution. Actually, its a cheat more than a solution, but it works fine. I'll try to resume the steps, but if you have any specific question don't hesitate to ask.

Maybe some steps are unnecessary, who knows. This is a matter of testing and testing and testing againt and Im a little tired. This is what I did and it worked. Here we go:

1) Get CoreAVC codecs. They are the best and offer a superb performance. Remember they arent freeware
2) Get KMPlayer. Its one of the best players out there, and fully configurable and customizable. Also provides amazing performance together with CoreAVC.
3) In order to activate the CoreAVC codecs into the KMPlayer as external decoder, follow this link: http://www.kmplayer.com/forums/showthread.php?t=3571
(Remember to use the Ctrl-Tab method explained to check that the setup is done correctly)
4) We are going to increase performance a little bit more. Press F2 (preferences) in the kmplayer. General>Playback>Priority(tab) and check SuperSpeed. You can increase the priority to high also. SuperSpeed mode is the light playback mode where some aditional filterings are avoided.
5) With these settings you can play smoothly 1080p mkv's in an old laptop like mine. You can experiment with the rest of the settings. Its amazing how many options you can control in this player. All right, now here it comes the real trick.
6) I have made a skin for the player based on an existing one, which consists in a black frame and the simplest navigation bar possible. This is the link: http://www.megaupload.com/?d=DYFQWKWQ. Double-click the file or just load it through Preferences>General>Skins
7) Now play the film you want. Left-click menu > Maximize window. And.... yeahhhh!!! We have emulated a fullscreen. I know, I know, there is a gray nav bar still down there that can be annoying....Let's make some magic to hide it hehe. Now enter the Bravia menu and look for PC Settings or something like that. Move the Vertical Displacement to a value where the nav bar is hidden, usually -4 pixels. And that's all, you have now a completely simulated fullscreen. Enjoy the film! ;-)

PD: I use just the TV as main monitor in the ATi (nVidia in your case) control center in a resolution of 1280x768, I mean, disconnect or deactivate the laptop LCD panel and put the tv as primary. The tv automatically detects the 1360x768 p 60 Mode.

Question No Sync error

Hi.. Sorry i was busy for last 2 weeks and did not check it here.. I just made my VLC setting such a way that it shows only the title bar and i also made an auto hide for the task bar. and now i play movies which is almost like a full screen with the title bar.. i did not find any solution yet.. still searching. Ihave never tried HDMI or DVI as i dont have ports in my laptop and S-video is not availavble in my Sony Bravia HDTV. SO i'm just using VGA.
