The Lonely King.
Bad news has come from NEC.
The new "updated" NEC 2690WUXi2 that should replace the 2490's twin-brother 2690WUXi has no A-TW polarizer!
The 2490 sadly loses its running mate.
No doubt, the 2690WUXi2 will be a great screen, but without A-TW polarizer there may be no equality with the 2490 anymore.
