cool! thanks for showing me that i didn't search first ;) im a bad poster.

but in my colorful rant i guess i was trying to say that samsung usually tells people when they do something. so if they were making LCDs for the psp then we will eventually know via these press releases. which as we've seen may come out weeks after it occurs.

and i've looked through 2 parts catalogues, samsung doesn't make any LCDs that match specs that would work or fit in a psp (YET as of print - FEB 2005).. sharp now makes 2

im not saying samsung will never make them for the psp im just saying i want the real news.

rumors aren't bad... its just that i searched around and found SO many other people making claims with no real support.

blah blah blah.. who's gonna open their NA psp?.. me again?????? please no i already broke one and now im unsure of myself... any volunteers?

a german professional IT mag (called c't) with a knack for toys tested the response time of the psp and measured that it takes the display 100ms to switch from total black to total white. this is of course very bad, BUT it is less visible than it sounds PLUS
if you lower the response time you have to crank up the power to reach good contrast values. which would also strain the battery even more. not speaking of the led themselves, which have to be better to make this happen.

if you think the ds is any better you are wrong

just load any jpeg with black parts into the psp and then move it around, you'll see how bad response time is. having seen this I believe ridge racer simply is hardware blurring which has nothing to do with the chip calculating anything.

maybe sometime, we get a refresh psp with better display, but for the moment we are stuck with 100ms which means 10 unblurred frames per second.

play untold legends, there is a LOT of ghosting with any charecter movement. I'm also seeing what appears to be overheating artifacts with this game (texture tearing and "sparkling") :(

no im still boggled by this one.. the first time i watched the movie on my na psp there was zero blur. but that unit had 9 dead pixels in it. so i returned it and got one with 8 dead pixels and more blur in the movie. so i figured it was the lighting. so i went back to the originating light source at home and i noticed more blur.. put the umd in my jap psp and noticed the same blur.. (one particulart part where peter is walking into is back yard to take out the trash after his birthday party. his face is all warped from the blur. also on scene switches you can see people lips and eyes on the next scene over someone elses forehead and what not)... anyway.. i took that psp back and got yet another one with finaly only 1 dead pixel.( my jp unit has at least 10, how hard is this to get right?) this one had no blur the first time i watched the movie... then after i played some games i started noticing blur in the grill of the cars in ridge racer.. later my wife wanted to see it play movies and i showed her and noticed BLUR.. grrrr i noticed this on and off wall power on both jap and na systems now. but it seems that sometimes the sytem does something to minimize since wipeout pure seems to have WAY less blur.

That's a bit re-assuring, maybe sony will fire up a new update with a fix. IF this is actually a software problem. I hope it is.

Just to add my 2 cents here... I've noticed significant ghosting on my PSP exactly once. And that one time was when my PSP had been left in my family room/basement area overnight where it gets pretty cold. The LCD itself was pretty cold, probably 40-50F I would guess. I've noticed this with other LCD products, I'm sure it's just inherent in their nature. Besides that one time, I have never noticed ghosting and I have been looking for it since reading posts like this one. If it was happening, I am sure I would notice it because the game I've been playing the most is Need for Speed Underground Rivals and the car I'm using is black end-to-end. It is where I noticed the ghosting that one time, but haven't since.

Hi, back again. I made a movie with a black 'pole' moving left to right (with studio max), and it 'seemed' to blur?? I say seemed, because it wasnt as apparent as the garfield clip, but it did have similar looking results. Sorry, AWhite I took so long to get back (work has been insane). You made one with a black square and it didnt? geez.. this is getting bizarre.. is it possible that its to do with the amount of moving data per frame? Maybe the mpg playback is limited and its just not keeping up, and maybe what we are seeing is frame delayed rendering? (although that seems a very whacky possibility). What happens if you make the black square really large? Also, what brightness setting do you run with (so I can use the same level).

yeah, i was so happy when i first got my psp and noticed there were no dead pixels. then i got even happier when i saw the crazy image quality of the spiderman umd.

then i got sad after seeing it ghost like mad :( what the hell was sony thinking? the videos would be so great to watch on this if it wasn't for the ghosting issues.

and why is it that wipeout pure seems to not ghost AT ALL?

I didn't notice Spiderman UMD ghosting yet but I encoded an episode of 24 and it ghosts like mad (many dark scenes).

LCDs are in fact extremely sensitive to temperature although they're usually fine at a comforatble room temperature. The colder the display, the slower the refresh rate, the hotter the temp the faster it is until it heats up too much and you get dead pixels.

strange, so far I've seen three PSPs and ZERO dead pixels.
However the third one had a fracture between the backgroundlighning and the actual LCDs. this tiny fissure resulted in a visible red line. I took a look with an eyepiece and it was no damage to the exterior casing or any dead pixel.
