VISTA display problems

Hi guys, I'm trying to test out VISTA on my HTCP, and have it hooked up to my AKAI 50" DLP TV, but it won't display, it all goes black after it boots. I tried different drivers but nothing works. The TV is hooked up with HDMI to DVI to my 7600 GT card, and when I hook up my 19" monitor I can see on that one,a nd the computer works fine with XP loaded.

Thanks Micael

yup...
Vista, Nvidia, and DVI don't mix yet.
Been that way for a while now.
Sad, isn't it...

Are you sure you are using a resolution over the DVI-HDMI interace that the TV will accept.
You probably need to be using 480p, 720p or 1080i or maybe somsset of thiis list. HDTV HDMI/DVI receiver chips are not designed to accept all of the PC resolutions that PC moniotr DVI interface will accept.
Check your TV's user manual.

Thanks for testing Vista; consider what you are doing a service to others. Expect frustrations, and don't allow Vista on a system you need to use reliably. It's beta form is truly pre-pre-release, and Microsoft's willingness to make it so readily available surprised me.

Well the problem is that it work at the first installation, but then I couldn't get it to fit to my screaan, was just to big. So I decided to take it of and then changed my mind, and now I can't get it to show up at all, really want to test it out for the built in Media center and it's functions. Like it a lot on my regulare computer, where i watch everything on a 24" Dell screen, but no TV card for the Media center :( oh well, I guess I can't give up after only 2 weeks of trying :D

Well thanks for the suggestions, and if anyone come up with anything, please let me know.

Thanks Micael

If "Too big for the screen" means it is zoomed in about 5% then you are probably trying to run PC applications on an HDTV and most HDTV's overscan theirHDMI/DVI and component interfaces in order to emulate a standard CRT TV which have always overscaned their inputs. You need to use a VGA interface or to apply Overscan Compensation in your graphics card drivers. The overscan compensation will Zoom in the image so that when the HDTV oversscans it your display will appear correctly for PC applications.

Yeah that is what it is, but how to fix that in VISTA, XP it was easy, used the keystone function in the 93.xx drivers, might be a better way to do it as well, but it worked. Well first I have to get it to work at all under VISTA.

Download the NVIDIA classic driver user manual from the same downlaod page as you downloaded the NVIDIA Vista drivers it will tell you how to perform overscan compensation.

Thanks, I will take a look at that, as I need to activate the Keystone everytime I start the computer, bugs me a bit, bit it works.

Just an uppdate about VISTA and my HTPC. Just got my hands on a VISTA 5472, and now I'm able to watch it on my TV, but need to find out how to fix the overscan. So soon I hope to be able to be fully up and running :) So to me it seems like Microsoft is geetting closer and closer to a good product, but it sgouldn't take so long.

OK, found out that the Media Center in VISTA actually adjust for overscan in the setup :-) so now that part works, but still ahve to find the same option for the rest of VISTA.
But I now have another problem, as the Media Center won't play the file's I have ripped down to the HD, I have used DVDFab and can play them perfect using WINDVD as well as Power DVD, but it would be nice to be able to do so in the MCE interface, all in one. Anyone having a solution for this.

Thanks Micael

Has anyone been able to get an MPEG2 decoder to use Video Hardware Acceleration?

DXDIAG reports that the drivers enable hardware acceleration, but the in-box MCE decoder doesn't seem to use it. I have an Nvidia 7600GS card. I've tested with both ATI 1x00 series cards and also an Nvidia 6600GT AGP & Nvidia 6150.

I've installed the NVIDIA purevideo decoder and that doesn't seem to take advantage of the video hardware acceleration either (although the checkbox is checked). Is there a hack or workaround? It's been like this in Vista since Beta1 -> 5472.

5472 finally fixed the display output, but now all I need is hardware acceleration! High Definition content is unwatchable without the hardware acceleration.

I'll try disabling UAP/UAC completely and reinstalling the Nvidia decoder tonight. I think it might be messing with it.

I have the same problem - Hardware Acceleration isnt working. HDTV is watchable and barely skips, but I can tell it doesnt look as good as it did in XPMCE - please let us know if you find a work around. Hopefully RC1 will address this...

Nope, I just got through with 4 hours of testing on pre-RC1 released yesterday. Everything is just as bad as with Beta 2 as far as video goes. Sigh... I had such expectations :(

I'm having no troubles yet on pre-RC1 build 5536. DVI-Hdmi on nvidia 6600 to Sony KDFE42A10. It had set the default rez on the Sony to 50hz, changed it to 60 and it was all good. I don't think I've played anything higher than DVD rez yet though.

I found that WinDVD's MPEG2 decoder works with hardware acceleration under Windows Vista. I don't like it as much as the Nvidia decoder, but it does work and it makes watching HDTV possible.

funny, I tried playing the included sample avi files (like the butterfly one) and on my 3.4ghz PentiumD with 6800GTOC it played like in slow motion.... sigh.... :confused:
