I just got my E1705 today and it has the Samsung. I have to say it's not what I expected based upon the comments that others have made about the stunning quality of the Duo Screen.
Now, I have to admit that the light leakage is very small....probably the best that I have seen. The overall brightness of the screen is where it falls down the most. It is actually darker than the WXGA screen that I have in my 9300! The colors are slightly washed out, so I'll have to spend some time tweaking to get the best results.
The overall clarity of the screen isn't as sharp as the True-Life screen I had in my original 9300 I got in December (that I had to return because of a broken keyboard). I have an older Sony Vaio that is currently on Ebay, and I can't believe how bright that screen is. The resolution is nowhere near the WUXGA and it's only a 15.4 inch screen.
You really don't know where a screen stands in overall quality until you can see it side by side with other screens. In a scale of 1-10 I would give it a 7.
p.s. Man does dell pack a million an one pieces of software crap on this machine. WHOA do I need to reformat QUICK!
