External Screen = image quality ?

The thing is, DVI connectors have pins for both an analog signal and a digital one, whereas HDMI only has digital.

Oh i see what you mean here.

Damn , i want to find thoses adapters back and try again to see if i wasn't wrong , but i was pretty sure that this had work in the past. Maybe i was drunk @ Lan party -_-

Just got my Amazon cable , and i do not recommend it :

It seem that there's two " position " : i plug half of the cable , good picture , no parasite
Then , if i plug it to 100% , the screen goes black for a sec, and then appears with hundreds of parasite.

Just check the DVI Cable that came with the screen , there's only " half " of the pins on it. On the Amazon one , it's full ... I'm tired of RMA on EVERY SINGLE HIGH TECH PRODUCT i got , so i keep it , half pluged ...

I assume that this is caused by the " Ethernet " function of the cable that is probably not compatible with my screen ...

It's perfectly normal for the DVI connector to not have all the pins. Explanation: Digital Visual Interface - Wikipedia, the free encyclopedia

Which connector do you have to push in half way, DVI or HDMI?

[Catzoo]

The DVI one.

Any ideas ? ( on your link , the DVI cable i got with the screen is " DVI single link " , and the Amazon one look like " Male M1DA " , the last one )

First of all, that can't be an M1-DA connector, because that one has more pins than DVI. It's dual-link DVI.
Secondly, it can't be ethernet, because DVI doesn't carry that. I have no idea what could be causing that.

So you think that Amazon cable could be deffective ?

Seems to be solid , in a good shape , i would suggest something's wrong before i return that cable ... Tsss i'm tired of doing RMA and such.

Btw , thanks for your help ( and sorry for that ethernet thing , i was kinda disapointed to see that the HDMI cable i got from Amazon had an " ethernet " function wich i didn't even know that exist , so i thought that the DVI HDMI cable had the same function. )

How do the "parasites" look anyway?

Here's a pic taken with my phone , sorry for that crappy quality.

Thoses " blue " parasite cannot be seen on a Black nor white , but on other colors you can see them ( like on this pic )

Thoses " parasites " are somehow " moving " slowly or " blinking " , dunno the good word for it sorry , but it move a bit.

I've really no idea why is that happening and why does plugging it half-way fix it. Those artifact shouldn't be possible with a digital signal. You might try asking in the Hardware section or in some AV forums, this might tickle someone's curiosity.
