Greetings
I'd like to vent my experiences with Benq 2400PT display. I currently have Benq G2420HD (TN) and a "vintage" Eizo S1910 (PVA). The main reason why I wanted a new display was the supposedly higher contrast ratio and better black levels which all reviews have been raving about. I watch a lot in a dark environment (movies & gaming) so the backlight bleeding is a major factor that bothers me.
When I turned this new 2400PT on, my first impression was WOW, what a horrible blue glow! There was not a slightest hint of those "Inky blacks" that has been often mentioned.
Of course the default settings were too bright, so I lowered the brightness down to 10 to match it what I'm having with my Eizo. Still a distinguishable blue glow. It can be seen even in a daylight with black backgrounds. Then I compared in a dark room side by side with my Eizo. It appears that the "black" (=blue) level of 2400PT is only marginally lower than Eizo. The problem with 2400PT's backlight is that it's intensity varies quite dramatically with your head position. It looks quite dark straight where you are looking at, but shines badly around. This feature makes it feel like a TN panel.
Taking this in account, This display doesn't feel like contrast ratio of 3000:1. According to Prad.de, Eizo 1910 can produce a contrast ratio of 1400:1 (140cdm2/0.1cdm2, 1000:1 stated in the specs). Judging by eye only, I can't see 2400PT producing much higher contrast than Eizo. Actually it feels much worse due to the above mentioned backlight variation with viewing angle.
I understand that there might be quality variations between the units. But I doubt another unit would make much difference?
Another issue is the color (in)accuracy. It's even worse than Benq G2420HD (TN panel). Something I didn't expect. Blue shades look completely off. Shades of aquamarine turns out to be more like violet or deep blue with 2400PT. Too bad there is no way I can manually correct it as I don't own any hardware calibrator. This was the reason I had to send this unit back for refund.
I wonder if it's just me expecting too much or what..?
Just my experience. Sorry for a long and not so enthusiastic post, but I guess I'm feeling disappointed. It's year 2011 and still no mach for 6 years old Eizo.
cheers
