Vista - HDMI to TV video flickers

I've searched through several forums and googled my life away for this problem to no avail, so now I'll see if any knowledgeable person here can help me.

I just bought an Acer Aspire AX1300 with Windows Vista Home Premium 32x and an Nvidia GE 8200 video card for storing data and, more importantly, to play shows and movies through my 1080p Mitsubishi HDTV. It is connected through native HDMI and the cable is high quality and works perfectly fine with my Gateway laptop to the same TV.

The video looks great as long as the screen is static, like on the desktop or surfing most websites. But as soon as any motion or video is displayed the screen starts to frequently flicker every couple seconds, and sometimes cuts out to black completely for 3-5 seconds, until the TV picks the signal up again.

I've downloaded all the updated drivers and even reverted to an older Nvidia driver through suggestions on their forums but nothing has solved what seems to me should be a simple problem. I also changed the refresh rate (with the new drivers I was only able to select 60Hz or 59Hz, neither helped. The older driver had even lower Hz, but when I tried to change to them the screen automatically reverted back to 60Hz) to no avail.

I'd be incredibly disappointed if I can't fix this as the main reason for the purchase was having a desktop set up to view Netflix on my HDTV. Thanks for any suggestions/help.

2 questions.

1) is the cable screws tightened, or is the cable just plugged in ?

2) what is the refresh speed on your hdtv ?

It is a plug in HDMI cable, one that I've used with my laptop to connect to the same TV that has worked fine.

The refresh speed defaults to 60Hz, which is the highest setting on the Nvidia control panel

Hello,

I've got a similar problem. I have a Compaq Presario CQ60-430SA laptop and it seems to flicker whenever I try to play a movie through my LG HDTV.

It plays smoothly on my laptop but flickers on my TV. Its such a headache and there must be something I can do about it surely?

Have you tightened the screws on both ends of the cable where it plugs in ? Doesn't have to be tight, you just don't want the cable to wiggle.

It's not a VGA connection with screws, it's a simple plug on both ends and it is not loose at all. As I said, this cable works fine when plugged into my laptop to the TV so that is not the problem.

On the video cables I have there are knurled knobs for attaching the cable end to the connector. I just call them cable screws.

If it works on the laptop to the tv, but not the desktop to the tv... have you checked the connector on the desktop ? Could be some bad or loose pins.

Oh, and for refresh speed, I meant how many milliseconds is it. My computer monitor refreshes in 5 ms. So it handles motion okay.

But my hdtv television, when I fast forward a dvd or a vhs tape, the screen blanks. I haven't checked the refresh speed.
