Big TV Good, Small TV Bad (1 Viewer)

[robh]

Hi,

I'm finding the intial TV screen really jerky, but full screen TV fine and DVD also fine.
Any suggestions?

Hi. With no info to go on, you can not get any support.

Please read the stickies and provide some information as in the support templates...

Generally the screens that have a mix of TV and GUI need more GPU then just full screen TV, due to the TV scaling, GUI drawing etc. If your graphic card is not up to the job then your CPU may need to work too hard causing the jerkyness.

Yeah, you'd think it would be doing more work, but task manager suggests otherwise. CPU usage is actuall slightly lower in the first screen (averaging about 25% v the 30% average of full screen).

The CPU load really seems to cycle up and down in either mode. Is that normal?

GForce 5200 (PCI)

PCI not AGP or am i misunderstanding, as a non AGP card might not be a fast enough interface to the motherboard.

Mine goes between 10-20% with no visual cause as to why, with GUI showing.

Yep PCI (mb only has one slot)
Integrated graphics are AGP, but I never got working quite right with MCE or MP (think they're only partially DX9 compliant).

Is there anyway to test if this is the cause?

 

[robh]

Just noticed that dvd runs fine in a window (from front screen) so it can't be as simple as underpowered graphics card.

Could it be the pci splitter I've got in there (to enable graphics and tuner to run from the same slot)?

Pretty sure it wasn't a problem with mce but not sure if mp does something slightly different...

 

[tkortell]

Maybe you can try to change the PCI latency then if you have a PCI GFX card. There should be a thread about that somewhere...
