I used to own a TN-screened new 3DS XL as well. To be honest it didn't really have significantly worse 3D than the IPS version (the latter being just fractionally better. I don't know how much of that is down to variation between individual units).
His is an XL unit.
No worries, glad it was useful. Hope you can get the type you're looking for!
Not true. Rich's non-XL 3DS didn't look like it has a TN panel. Unfortunately, most of the photos in his post are gone because pomf.se shut down. It should be noted that he imported his from Australia, so he's got one of the very earliest units.
His is an XL unit.
Thanks to both of you, I appreciate it. Yrael, those pictures are actually very helpful to have, just as another source for comparison.
I'm still on the hunt; the guy ended up sending me another photo, taken at more of an angle, and it was clearly a TN.
I've got another person who is going to snap some photos on a different XL. He says he believes it to be an IPS, so I might follow up for second opinions, if you all would be so kind.
Nintendo is just poking my OCD with a stick at this point.
