Philips 275E1S vs Dell S2721D - horizontal viewing angle compared

[removed]

This is basically meant as a bit of warning for anyone considering buying the Philips 275E1S monitor. I recently bought it and had to return it more or less just for this single issue - it has terrible horizontal viewing angles for an IPS panel (and a fairly low brightness, too - I measured 180 cd/m2, quite far from its listed 250 cd/m2).

Philips is on the left, Dell is on the right (and is consistent with what I expect from an IPS panel).

I have no idea what the hell Philips is doing there, but it's just horrible. You have to sit like a meter or more away to not see "vignette" effect on the screen, and if you move your head even slightly from the center of the screen, the far side of the screen gets noticeably dimmer.

It's a shame, really, because otherwise it would be a really nice monitor - good colors, nice response, perfectly tuned overdrive...

(I might post a more thorough review and/or comparison with the Dell later, if/when I get to it. But the main point is this.)
