Looking at it from normal distance I see no dead pixels. But I don't really know how visible a dead pixel is (?). When I make the a 100% white image and put it full screen and look very very closely, I can count 11+ tiny dots that either flicker a bit or are black. Dead Sub-pixels? Anyway there are no problem.
Maybe it is dust on the surface? Sometimes dust any real defect pixels looks the same.
Anyway searching for dead pixels needs displaying not only white, also black, red, green and blue. Pixels, which constantly shows everytime the same colour are full dead pixels. If they shine only in some of it and not all, that it's a dead sub-pixel.
But anyhow, if it they not bother you, maybe it is better not to search something for.
But some problems show..
Button for Auto configuring the screen gives only a OSD message "digital video input no access". And I do have this connected with DVI-D cable.
Also they were no drivers of any type on the cd's and there is no downloadable drivers for photon19vision on LaCie website. I now have set up as "Plug and Play monitor". Windows doesn't regonize it as anything else.
Usually you don't need any monitor driver. It does not make anything better any it will not solve your problem.
I assume, that the DVI port of you grafic board is not activated. To do that, you have to go in th setup of you grafic card driver and activate the digital output. After reboot the LaCie should react on the DVI connection.
Also consider to output digital DVI only at 60Hz. TFTs don't need higehr frequencies.
Also some TFTs can be disturbed by conecting both the analog DSUB and digital DVI at the same time. But usually only TFTs can be affected by this, if they don't offer a switch button between both inputs or a similar option in the OSD.
I hope, I could help you a little.
