Those scanlines are all fucked up. Your HDTV is scaling the image improperly.
What is the model of your TV?
Indeed. Ive finally started experimenting with scanlines this evening, and the result is not pleasing to say the least. I have a Philips 50" tv in the 3000-line, so its not exactly top of the line, but it has worked fine until i started experimenting with scanlines. Would definitely love some advice on what settings to tweak if somebody else has a similar tv!
Edit: One of the worst things about this tv is that there are not that many tweaks possible, but here we go:
In the picture menu I have:
Mode - I normally use Game-mode, however, the weakness with game-mode is that when enabled it doesnt let me tweak a lot of the other settings, so right now i have it at "sports" so i can customise.
Contrast - this is at max which is 63
Brightness - this is slightly below middle (30)
Sharpness - slightly above middle (20)
Colour - i just turned this pretty high when i tried to emulate RIchs clean picture, so its now 50, which is about 4/5 of the way.
Power Save Mode - disabled
Backlight - high
Noise Reduction - off
Then Advanced Picture Settings:
Dynamic Contrast - off
Colour Temp - normal
Picture Zoom - full
Film Mode - off
Skin Tone - i have this at default which is in the middle
Colour Shift - same here
RGB Gain - i just upped this from middle to max on all three colours to get that brightness that Rich was having.
HDMI True Black - this is no on.
And thats the settings i can tweak on my tv proper.
