Hi

When using Vista RTM and the latest ATI drivers (8-31-100_vista32_rtm.exe) on my Radeon 9600 Pro and Sony 46x2000 LCD TV through DVI-HDMI, I have got a continual problem whereby when swapping inputs on the TV and then going back to the MCE input, the screen is black (ie no signal).  Nothing has crashed as such, and I can get the screen back if, for example, Vista is at the desktop and I press the Media Center button on the remote.  It seems like a sync problem to me.  I do not have this problem using exactly the same hardware and TV when on MCE 2005.

I have messed about with refresh rates and resolutions but no joy.  For info, the TV is native 1080P through HDMI

Has anyone else come across this, and if so, is there a fix?

TIA

I'v had this same issue and I honsely think its a issue with the drivers still.

I have the ATI x1600 512 card, I've been using the DVI out to the TV, (which gives the best picture, but I've tried swapping to the svideo to see if that would saove the stutter issue I was having, when I'd try going back to the DVI out, I'd have to go into remove the svideo cable from the graphics card as well as going to the Catalyst Control Center and manually tell the software I'm now using the DVI out.

Before I was using the Catalyst control I couldn't swap back

Hope this help

 

Thanks for confirming - at least I know its nothing to do with my setup as such.

Cheers

So . . . . I just finally jumped on the Vista bandwagon and I ran into this problem. I was just wondering if anyone has found any solutions to this yet? I am really hating the fact that I have to reboot my PC in order to watch TV or else be forced to leave the TV on 24/7 . . .

have you tried the display detection option in CCC...auto or manual detect...

maybe that will help the issue untill new driver release..

i swap back and forth between VGA and DVI (with hotkeys)  with no probs

Actually that came to mind, but it didn't work. *shrugs* I guess until ATI figures this out I'm stuck rebooting my HTPC every time I turn on the TV . . . grrr.

I'm having the same problem using an ATI x700 Pro (obviously using Jan. 29 drivers) connected through a Pioneer receiver to a 42" Panasonic Viera via DVI -> HDMI -> HDMI. When I switch modes on the receiver, I usually can't get back in due to the black screen. This usually depends on how long it has been before I switch back. When I can get back in, the resolution will often have switched back to a very low resolution and I have to switch it back to my custom HD resolution through the Catayst Control Center. The desktop shortcut on created to the profile doesn't even want to work.

With the old drivers, I would be able to RDP into my Media Center PC from another machine, which would bring it to the logon screen, and pressing "enter" on the keyboard would log me in and often restore the screen. Placing the machine into Standby and waking it back up would often resolve the problem, but that's no longer the case.

By the way, has anyone tried saving the settings using Powerstrip and attempting to restore them using a shortcut key? I'll probably try it today if time permits.

Anyways, I'm glad I'm not the only one having this problem. I think it's safe to say that it's ATI driver-related at this point in time.

 

Definitely driver related at least I found out how to make ATI's temporary solution of "unplug the monitor and then replug it back in to restore the video signal" works; which avoids having to shut down the PC (which was wrecking havoc on my recordings). The thing I discovered is that while MC has control of the display it is almost like CCC can't control it or even interact with that. I just Alt-F4 MC and then disconnect and reconnect the monitor and voila display restored! Oh an Turge I tried your suggestion of using the Powerstrip shortcut, while it resets the display properties it for some reason will not restore the video signal . . . .All I can say is that Vista is the worst driver disaster since Win95 . . . what a mess. While yes I do appreciate new driver models and new approaches . . . I do not appreciate them breaking everything that works in order to make the OS more "MAC" like . . . yeah I said it . . . . I feel better now I think I need to go unplug my HDMI cable so I can watch me some Fraggle Rock . . . Oh before I forget I submitted a ticket to ATI with the new information about MC not allowing their temp fix to work. More info to come if I can get it.

Ok . . . canned response from the tech monkeys . . . submitting again.

FYI, I'm having this very sam problem.

GeForce 7600GT HDMI.
Sony Bravia 52" LCD.
HDMI -> HDMI cable.

Whenever I change inputs, the computer reboots instantly. It also happens when I turn the TV on from an off state.

It's getting very anoying. It was never this way under XP, so it's clear that it's a Vista/Vista driver problem.

Yup!  I got the same issue here!  I'm running Retail Vista 32bit with an ATI X800XL card going to a PIO Plasma by DVI to HDMI.  If I change inputs or even turn my TV off (PC still on); then the TV on again, the signal is gone but I can still hear the audio.  Just loss of display signal.

I too think it's a driver problem.  I once had this same problem with MCE 2005 with the same CARD and older drivers. I put in a bunch of tix with ATI and they eventually fixed it within their next couple of driver releases.

But it looks like it's back again!  Now with Vista!  I put in my ticket with them on this new problem. Hopefully they fix this (again) soon with Vista and their drivers.

I suggest everyone in this forum that is having this issue or anything similar to it, regardless of the ATI model card, to submitt a ticket (www.ati.com). 

why dont you guys make hotkey shortcuts(ATI Profiles Manager) this way you can refresh what ever display setting you need..hmmm......does it work?

temp fix......

After rebuilding my machine, I find that putting the machine into standby and waking it back up usually works. I haven't had to reboot it yet.

I tried creating a shortcut and it doesn't seem to do anything. My Powerstrip shortcut to restore the default profile works well when Vista decides to lower the resolution on me.

This wouldn't work for me, as the computer actually resets when I change back to the HDMI input on the TV. The second i change to the HDMI input used for the HTPC, the next thing I see is the BIOS POST screen.

My (wild) guess is that when I change to the HDMI input, the TV requests a hand shake from the computer (HDCP?), and this hand shake signal kills the computer.

But that's just me guessing...

google ATI Beta 7.2

ive been using 7.2 for a week now,, all seems good and stable.. maybe this will help....
