TV-out related issues

[P-J]

Hi all, a quick question if I may.

I've got a GeForce 7800 something-or-other and am using the multi-function connector thingy on it to connect composite out to a TV.

For some reason the largest resolution I can use with the TV is 640 x 480. If I go any larger it becomes like a 640 x 480 viewport so I have to scroll around the screen with the mouse.

It's a normal PAL TV so surely it should be capable of 576 lines or something similar (?)

Any ideas on how to get a better resolution? PAL gaming in WinUAE is a bit sucky in this res

(I'm using the latest nVidia Detonator drivers and I had the same issue with my old 6800, with older drivers)

There is an option in Twinview to scale rather than scroll.

Are you using Application zone mode or Virtual desktop rather than Clone mode or Application Exclusive?

I've used a 720x576 WinUAE screen with my Twinview and a TV several times.

Pissflaps! I'm using clone... Is that a problem?

I'm using clone since I'm guessing running WinUAE full screen on twinview/dualview would display it on my primary monitor, right?

Clone should be fine.... perhaps there is now an advanced option for clone... I dont have Nvidia at work so I cannot test.

I think you can use application exclusive too.

Twinview will only work upto 1024x768 without panning and scanning. You sure that your resolution is correct?

I've tried all manner of resolutions for the TV.

640 x 512, 720 x 480, 720 x 512, 720 x 576 and so on. Just comes up with a 640 x 480 screen which I can scroll around :/

I'm at work also right now so I can't fiddle with the settings :/

You can definitely do higher resolutions than 640x480

May be that you should try TVTool, it WAS a superior implementation of TwinView?

It might not work with a new card, development stopped as Nvidia significantly improved their Twinview support to the same level as TVTool.

Thanks for the heads up, I've not seen that before. I'll check it out tonight and report back!

It doesnt work with a card as new as the 7800 I am afraid.

On the contrary! I just tried it and it did exactly what I was looking for

Thanks again mate.
