i only have a few more days left before my 30 day return time frame is up. i am in a big bind.
basically i've been wanting this monitor and saving for a long time and finally was able to buy it couple weeks ago. at first i didn't think much cause it just looked so nice, colors are vibrant, much better than my previous C-PVA panel from Samsung F2380 (which suffered from black crush issues).
a couple days ago, i decided to bust out my Spyder2 Pro to do a calibration and tincker around and started doing some testing. the reason i decided to do this was because i started to notice some what i thought was backlight bleed while gaming at night in a dark room. but after doing some display uniformity test, it turned out the majority of what i thought was backlight bleed was actually IPS glow. so that set my mine to ease. the overall uniformity of the display is less than 11% deviation across all 9 quadrants of the monitor, which is IMO very good for a none professional (Lacie, or Eizo) monitor.
but here's the real problem, i moved onto contrast ratio testing. i like running my display at roughly 200~210cd/m2 brightness. but at that brightness, the Spyder2 registered a 0.6cd/m2 reading for black. the darkest reading i could get from other area of the panel was 0.57cd/m2, which is still alarmingly high consider most reviews i read online saying this display should have around 0.25cd/m2 black at 200cd/m2 brightness level. which means, at 0.6cd/m2, it puts my current display at roughtly 333:1 contrast ratio, as oppose to what should be roughly 840:1 real world testing based on other online reviews, since other reviewers are getting 0.25cd/m2 reading at 200cd/m2 brightness.
i am at a bind. i don't know if this is because my Spyder2 is not designed to calibrate LED backlit panel "or" because my monitor is inherently defective. i don't know which it is.
the only way i can get a 840:1 (ish) contrast reading is lowering the brightness all the way down to two bars, which is something like 40~80cd/m2 (can't remember on top of my head). and at the lowest lowest brightness setting, which i don't think anyone should ever use this setting in real world... at 24cd/m2 brightness.. the black is registered 0.001cd/m2, or roughly some 24000:1 contrast.. but no one is going to run the monitor at that level, or anything other than at least 50% brightness.
so basically at 100cd/m2 brightness level the contrast is stil at 335:1 (ish), and the same with 200cd/m2, and same with 372cd/m2. if i boost the brightness all the way up to full (372cd/m2), black level actually registered whopping 1.17cd/m2!!!.
i don't know if this is just the Spyder2 that i have that's having trouble with the LED panel, or that my LED panel is defective. other than that.. this monitor is awsome... with great colors.. and after calibration it looks even better with DeltaE less than 1 (0.7 to be exact). it has a little bit of backlight bleed at the lower left but is generally pretty uniform, and is not plagued by yellow tinge issue that previously reported by other 24" owners.
the contrast looks fine in a regular lit room to my eye..
i just don't know what to do.. should i return it.. and go through another round of monitor lottery? (i already had to previously returned one cause last time i ordered the wrong one. I ordered the Thunderbolt display, as oppose to one with the display port)
