Jerky picture


Standard Member
I have connected my HP pavillion PC running Vista to th TV using HDMI cable.
The TV picture is very jerky when playing a file through WM but fine on the PC,does anyone know the answer to this please.

Probably related to either the refresh rate of the TV not matching the media clip you are playing or your PC graphics card is struggling to keep up.

A bit more info required, like PC spec, media player version, clip properties etc.

My guess would be refresh rate. Press the info button on the remote and it will tell you the fresh rate (50Hz or 60Hz.) This needs to match the frame rate of the clip for smooth playback.

Make sure you are only outputting to the TV screen and not any other LCD screens, as this may affect the ability of the graphics card to drive the TV at the correct rate.

How would I change the refresh rate on the AVI clip ,the tv is 60hz if that refers to refresh rate, and the PC is 60hz.

I'm not clear what the problem is, what's WM?

It sounds like you're saying the picture is ok on the monitor but jerky on the TV, is that correct?

Yes Windows Media Player.How would i go about upgrading the Codec driver,and that is correct,the pc picture is ok but on the tv it is jerkey.
I am using a programme called Ultra Mon to mirror the pc monitor on the tv

Ultra Mon is not a program that I am familiar with but it could well be the problem.

I have the option on my machine to 'extend' the desktop through the traditional graphics options, don't you?

To be honest, I wouldn't worry about the codec pack as VLC will play anything you throw at it and I would look into using the Nvidia driver to extend the monitor.

Should you wish to though;

KLite Codec Pack

Thanks to you Guys all is well ,used Nvidia to mirror the two monitors and using VCL, perfect.
Thanks a lot for your time,I don't know what I would do without this forum
