is it just me, or is the response time awful?
anything vibrant or of high contrast smears terribly during movement.. e.g. a moving stick figure on a white surface becomes a blurry mess.
this is the screen, right? is the phat ds better?

Not happening here. Could you post a video or a screenshot of the smeering?

no camera, but try this on hardware
http://rapidshare.de/files/29364647/smear2.0withsrc.rar.html
on my 16ms pc lcd on dualis, dsemume, and no$ it is fine,
on dslite hardware it has obvious smear problems.
edit> new version with stick man and SOURCE
press R to go faster, also smeared

Yeah I see what you're talking about. I don't know if it's the screen, or it's just the code. Perhaps you could post the code here?

its as simple as it gets, i threw it together with palib, made a white static bg and one sprite with pagfx. init pa, pacreatebg painitbg, pacreatesprite, if pad.held.up y-- pasetspritexy etc.
but im positive its the screen.. once i noticed it i saw its happening in my bigger apps too, on both backgrounds and sprites, regardless of code, its just less noticeable when theres not so much contrast or much slower/faster movement.

Well, I tested it on my old DS, my sister's old pink, my Lite and an emulator.
All the DS units indeed do blur the sprite, but in a different way. On my Lite, the darker tone 'takes the lead', on the pink DS it's the lighter tone and on my old DS it's somewhere between. Not much of a big deal, though.

mahe thanks for the information!
for me its a bigger deal on the backgrounds, not so bad on most sprites because theyre constantly moving, but make a background with some black outlining and scroll it a little, its pretty noticeable.. im going to have to go over my graphics with some lighter colors it seems.
i wonder if there are any different screen types on the ds lites, i'd like to get my hands on some jap/euro models and see.. might even be variants in the different usa manufacturing runs already. if i could find a threshold for what is noticeable on each model i'd be able to automatically check my tile data for problematic neighboring colors..

dont all LCDs blur slightly?
#98261 - mgaijin - Mon Aug 14, 2006 11:23 am
dan: the blur on my pc lcd is significantly less noticeable in all emulators, it seems the dslite screen has a slow response time in comparison to current lcds on the market, thats what im trying to confirm

I always notice a slight color shift (colors appear darker when they move) when moving high-contrast images, nothing to worry about, my olde laptop does the same.

my old laptop does too.. my new (older than the dsl) lcd does not.. i'd be less concerned if the ndslite wasn't a brand new device riding mostly on the screen quality

A handheld must save energy somewhere right?
But I still wonder if you're correctly waiting for the VBlank. Are you?

backlights take energy, not lcd response. i think it has more to do with conserving $ than energy. yes.
#98286 - Dan2552 - Mon Aug 14, 2006 1:28 pm
well older LCDs would be cheaper, so yes, it seems to match the cheaper situation ;)
By the way, I ONLY have a old LCD (Panasonic Cf-27!!) - I didn't know newer 'fixed' the blur thing

I've noticed more blur in scrolling games on my DS lite than on my DS phat, but it could also be that I can see the screen that much better!
Look, we're talking about $130 device with two screens. Of course they cut corners. I'm sure the response time is horrible compared to a few hundred dollar monitor!
