Under specs, it says 1x DL-DVI and 1x SL-DVI. You should be good to go thumb.gif

WARNING!!! MY ACHIEVA SHIMIAN IS SUFFERING FROM "BURN IN"!

I do not know how this is possible, but it is very clear! DO NOT BUY, will update monday!
post #2473 of 4784
I'm curious why these sellers list the brightness for the crossovers different. 350 vs 380 vs 420 cd/m²?

My thoughts exactly, unless you leave it on a static image for weeks or something.

Do you have evidence of the burn-in and was it overclocked to 80+Hz?

He has a shimian so if he did increase the refresh rate it was probably under 70 at best. Any pics of the burn in?

Burn-in is possible on LCDs, although I'm not quite sure as to the exact mechanism. My Dell 2005fpw (early S-IPS) displays 'image retention' every now and then where if I leave a browser window open for a couple days and come back to it, I can see the outline of the browser window and some of its contents for 30-60 minutes until it eventually fades away.

I work in IT, and we have an older HP L2045w here that has the "Windows XP" screensaver logo 'burned' into it in various spots since it's always sitting at that screen and has been for years. Weird, but it does happen.

Its called image retention, but is usually cured by leaving the monitor off for a few days or playing a rotation of solid colored screens to unstick the pixels.

I had just received it and set it up, and had to go. I cant take pics or update on the status until Monday, as I do not have the monitor with me.

It takes about 15 seconds for "image retention" to start, and it becomes more and more crisp after that. Give it about double the time away from that image and it fades away.

Will be talking to red-cap about this and see what he has to say.


Note that these pixels are not stuck. It is like a ghost image on top of the other. They do change.

Copied from the my first post about the monitor:
EDIT: looking more carefully, im not sure how much is dust and how much is stuck pixels. if i move my head left to right, they appear and disappear. i couldnt figure out how this made sense for either of them... any ideas? if they are stuck pixels ill definitely be trying my luck on an RMA.
