Nestopia setting for LCD?

[peppers]

I want to use nestopia I use a 32 inch LCD as a monitor but you get those lines in the screen when there is movement. can I change the setting to be rid of it?

I believe this effect is caused by the NTSC filter, and it is present on a real NES, no? If you don't want an experience close to using an actual NES, with all the pros and cons, you can always disable the filter...

What lines in the screen?

Do you want to emulate an NES console (with all its NTSC video warts) or a PlayChoice-10 arcade board (with its "cleaner" video)?

[peppers]

Regular monitors do not have this issue, its a HDTV or maybe LCD thing it is paticularly apperint with games such as RPG's, this happens with emulators for SNES and below. it appear normal when holing still but when moveing around you often see some lines in the screen as if a few lines are not getting painted on the screen and its skiping to the next ones in small groups. I am unsure how to explain it better.

Does it happen on a non-emulated Game Boy, Game Boy Pocket, Game Boy Color, Game Boy Advance, Game Boy Advance SP, Game Boy micro, Nintendo DS, or Nintendo DS Lite?

[peppers]

No, I am thinking maybe a minor scan rate incompatability or something. I don't know, I don't know much about displays.

I think you're talking about the refresh rate/LCD response time. The effect only happens during scrolling right? I think it's due to the screen not refreshing fast enough. You could try running the emulator in a higher resolution maybe. Just a suggestion.

[peppers]

Yeh I tryed the highest setting my video card supports and it did not help.
you are correct about the scrolling.

[strangenesfreak]

Setting your monitor to a refresh rate of 60 Hz (or a multiple of 60), turning on "Synchronize to refresh rate", and enabling VSync (Options -> Timing) should help provide the smoothest experience possible. On my monitor (with a 60 Hz refresh rate), disabling VSync causes those page tearing line effects.

All of that applies for NTSC games, which run at 60 Hz. However, if you want to run 50 Hz PAL games as smoothly as possible, you may want to try setting your monitor's refresh rate to a multiple of 50 Hz.

[peppers]

Thank you strangenesfreak, that corrected the problem.

But that's not exclusive to LCD monitors, CRT monitors also suffer from tearing quite often.

[strangenesfreak]

Why peppers originally considered LCDs as the problem may be because page tearing may be more noticeable on LCD monitors than on CRT monitors. Because of the different ways these monitors light up pixels, pixel changes are sharper on LCD monitors than on CRT monitors. Light intensity of a steady pixel is generally constant on LCD monitors, but the intensity "flashes" from peak intensity to black during each frame of CRT monitors. Wikipedia has more on this.

He's not talking about page tearing from what I understand. He's talking about a strange effect on LCDs where things look normal until you begin scrolling and then there is this fuzzy/blurring effect. It stops when you stop scrolling. I've noticed it sometimes.

[strangenesfreak]

But what peppers described before seems to match screen tearing:

Regular monitors do not have this issue, its a HDTV or maybe LCD thing it is paticularly apperint with games such as RPG's, this happens with emulators for SNES and below. it appear normal when holing still but when moveing around you often see some lines in the screen as if a few lines are not getting painted on the screen and its skiping to the next ones in small groups. I am unsure how to explain it better.

I can't really tell on my LCD monitor if disabling VSync also worsens the LCD blur effect; I personally have a hunch that they aren't related.

[peppers]

It seems to me that turning on Vsync causes a slight delay, its not much but its enough to put you off when playing an action game.

edit: Iit would seem the delay was due to the controller I was useing.
