#10 Crappy quality

[Berend Dekens]

The tv-out in Windows has a rock-solid image, the image
produced by nvtv is crappy....

Bit shaky and colored lines 'shooting through'.
I've got a GF2 with a Chrontel 7007 chip.
Is this a problem in nvtv or something I can fix in the
settings somewhere? (No flicker filter is allready at max)

Does this happen in all modes? Did you try to change the
CRTC values (esp. HTotal and VTotal, don't forget
AutoApply.) What happens?

Also, please switch to email.

Quality is still crappy.....

I found a Chrontel register that kinda fixes the problems I told about
before... However, now I have a vertical distortion line and the colors look
weird....

I hava a similar card (GF2 w/ Chrontel 7007) and have
experienced similar problems. I was able to get a good
picture by first enabling the twin-view (in XF86Config-4)
using NVIDIAS "closed" driver, then start X. (getting an
underscanned picture on the TV). Then I disabled the
Twin-view in XF86Config-4. Started X, configuring tv-out
using nvtv, getting a good overscanned picture on the TV.
However, I have a dual-boot system, (Win2000/Linux), and if
I boot into windows I get the 'shooting through' lines/vertical
distorsion in linux after rebooting! I have bee able to
reproduce this a couple of times. This can be fixed by
applying the above procedure all over again.

I am experiencing exactly the same, with the same hardware.

Using TvTool in windows i get a nicely sized NTSC overscan
image at 800x600 which is completely stable.

Using NvTv's "Large" 800x600 NTSC preset i get the shakyness
and "colored lines 'shooting through'". I don't get this
with the "Small" and "Huge" presets.

I'm sure the picture is exactly the same size as it is using
TvTool - its just all fuzzy.

I understand chrontel chipsets are less configurable than
others, but it works perfectly in windows.

Is there anyway to fix this?

I'm running a Leadtek GeForce2 GTS with the same Chrontel
7007 chip.

I had flickering issues under Windows, but found that
switching the TV out mode to NTSC instead of PAL helped
(maybe my TV prefers NTSC signals even though I'm in Australia).

Anyhow under Linux I found that the PAL-X setting works best
for me, solid picture, with good colour. Try different TV
settings. I didn't touch the flicker/colour settings.

Hope that helps,
