Easy. If the viewing angles are listed as 170/160 or even 160/160, the monitor uses a TN panel. If the viewing angles are listed as 176/176 or better, it's probably a VA or IPS panel.

If you suspect the specifications are bogus, you can carefully lay the screen down flat instead of vertical so that you can view it from a direction that would normally be below the monitor (more than 170 degrees from perpendicular to the screen). If it darkens and inverts colors, you've got a TN panel. That's probably safer than pressing the screen.
Agreed. That's probably the single most obvious sign of a TN - IPS and VA panels do not invert the colors from any angle, while TN inverts at large viewing angle, especially from what would usually be below the monitor.
