scrolling pixel art

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? :oops:

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

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?)

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?
