scrolling pixel art

[J. Baker]

Is there a way to scroll pixel art without the slight blur effect of an lcd? Integer values didn't seem to help and don't know if it is even possible with a 60hz refresh or not.

Hi J.Baker

51 views and no responses, so may be I'm not the only one who doesn't know precisely what scrolling pixel art is?

Perhaps a working code snippet that demonstrates the issue?

I only viewed it because the subject made it sound like a viewable demo, but it turned out to be a coding question.

I don't understand the question. If you have a lcd screen with a typical blur effect when scrolling (due to pixel remanency), how could software suppress it ?

Yeah, I don't think you can overcome this kind of hardware issue with software.

This all comes down to the response time of the display device

[J. Baker]

Yeah, wasn't sure if it was because of the lcd display or not. Or if there was a coding method to alter how the sprite gets displayed to adjust for a sharper scrolling effect for pixel style art. Will look into it more but it may not be solvable due to lcd technology itself.

You are on a MBA just like me.
I cant watch a movie or play games like Left4Dead etc because of this effect. What is strange is that even if I connect it to a external source I get the same effect on the external display. Spent hours trying to find out if there is a way around it but havnt found anything.
On my girlfriends MacBook Pro this doesnt happen.

Interesting. I guess it just a per lcd display thing then. I do know that some have better response times. These MBA's must have a high ms delay or something.

You sure there isn't a motion blur effect in the game that needs to be turned off?

I hate that shit.. Seems to be the new "thing" to do with games.

Actually I dont see it that much in games, rather in full screen video (or in window video for that sake). I use VLC and spent hours trying to find a fix for it. Either processor, gfx chip or screen creates this. The gfx chip is strong (320M), while the processor should be enough so at the moment I belive its a screen thing. (but that would not explain it following to external source, now would it?)

[Zach]

I won't claim to know how the hardware works in this case..

But I suppose if it were being filtered through the LCD's own processor before being output that might have something to do with it?
