"Mode Not Supported" in Vista.

by biggweilo / February 28, 2009 1:50 PM PST

Hi There,

A couple of weeks ago I purchased a LA55A950 Samsung LCD TV. I've been very happy with it but have hit my first real hurdle.

I'm trying to hook up my Vista Media Centre PC to it via HDMI and getting a dreaded "Mode Not Supported" message. I've read the manual and am at a dead end.

My PC:
AMD Athlon 64 X2 4400+ Dual Core AM2
Integrated Radeon X1250 Graphics, HDMI, DVI, Component Outputs, S-Video
Microsoft Windows Vista Home Premium 32-Bit

Important to note is that I get visual when I hook the PC Via the PC in (15 pin SVGA) port but obviously no sound.

The manual has specified that I should use 1920 x 1080 @ 60Hz, which I have done. I'm also using Port 2.The HDMI input seems to work for a few seconds at the start of the PC's boot sequence but stops when the PC enters "Vista Mode". The only thing im not sure about is the manual says Interlace mode is not supported, and I dont know what that is.

I've seen a few similar threads in this forum but all seem to be aborted before completion. I promise, when this is resolved this thread will be updated with a solution.

Any assistance is greatly appreciated.

Driver issue

If you can see the boot sequence, that means that the hardware is properly sending, and the television is properly sending. When it enters "Vista mode", the hardware is no longer transmitting to the television which usually indcates a driver issue.

You want to make sure that overscan is at 0%, and that you have the latest drivers.

Hi HD Tech,

Sorry for taking so long to respond. You were right on the money - the pre-existing graphics drivers were only 6 months old however the new drivers made all the difference and picture is perfect now via HDMI.

I then had an issue with no sound through HDMI on my Realtek onboard sound card. I kept getting a "No Driver was supported in this driver package" error when installing the Realtek HD drivers. I managed to fix this by updating my motherboards BIOS from Asus (M2A - VM HDMI), which in turn added an additional HDMI sound setting to my BIOS and once that was enabled, it was all smooth sailing.

Thanks again Samsung and I hope this helps a passer by who may be reading this.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
