The U3100 has indeed scanlines (at least it looks like it, closely it looks like brick patterns), the very best of this monitor is you won't get the blockieness as you would on a computer monitor.
I've some pictures of the U3100 in action on my homepage (see below), so you might've a look at this. Never seen the picture of the U9200 so, the U3100 is only available in 13" and 19".
But better not use it to surf around and read emails, might 'cause some pain in your eyes due to lack of sharpness!
