AOC i2353Ph - IPS for a nice, low price
by Chris Heinonen on January 30, 2012 12:40 AM ESTOSD and Initial Readings
The OSD for the AOC does a good job and has all the controls available that you need. In making my initial settings and measurements, I noticed that the selection of the sRGB color setting really reduces the level of light output from the display. Since the sRGB standard calls for a specific level of light (120 nits), this is actually a reasonable thing to do as pushing the backlight level to be really high can cause color shifts on displays. From the OSD I was able to configure everything I needed for the display, including a single custom white balance control that I used later to set the 100% white value as close to D65 as possible.
For the AOC review, I made a couple of changes to the equipment used for reviews. I have added a new i1Pro spectrometer to my testing equipment, and so it will now be used for all monitors reviews I do going forward. This meter has also recently been tested in the NIST approved lab by SpectraCal to ensure that it has an average dE of only 0.4 and a maximum dE of 1.0 across the color spectrum. Spectrometers are also much less susceptible to drifting over time than a tristimulus meter (e.g. the i1Display2) would be.
The downside of the i1Pro is that it does not do a wonderful job with low light levels (below 20% stimulus), and so for the dark uniformity and brightness uniformity measurements I will continue to use my i1Display Pro meter instead. The color accuracy might not be as good as the i1Pro, but the light level readings are better for these tests. Hopefully in the future I will be able to profile the i1Display Pro using the i1Pro, which would provide the accuracy of the i1Pro with the speed and low light handing of the i1Display Pro. Because of these changes some of these dE readings might look better, or worse, than you would expect, but these new numbers will be more accurate going forward.
Uncalibrated, the AOC has a dE of right around 5 in the sRGB mode. This number looks very good compared to other monitors, but remember we are using newer, more accurate test equipment and the only other display on the chart measured with this is the HP LA22f. The worst part of the uncalibrated result is that the largest error occurs with pure white, which you are likely to have on your screen a fair amount of the time. Overall, however, this is a good number to see. Hopefully the calibration can further improve on this, but starting out at a dE of 5 is very nice.

My 6ms Dell 2407WFP has not only been perfectly adequate for games of any kind, I've never noticed it ghost. Ever. And I'm sensitive enough to monitor weirdness that SLI microstutter pisses me off.james.jwb - Monday, January 30, 2012 - link
I had one of these and I noticed some ghosting, but the main problem with them was input lag. You really want a screen with no more than 15ms input lag to be rid of issues. If you put a u2412m side by side with a 2407 and duplicate the desktop, you'd notice it simply by moving the mouse.The old S-PVA screens never really got input lag down to acceptable levels.

I've still got a 2408WFP sitting around my place, and I can definitely agree that processing lag is too high. Even my wife -- a non-techie user -- noticed it when I recently switched her to that display from an IPS panel. She thought the problem was the mouse, so I switched mice and the problem was still there. If you only ever use an S-PVA display, you may not notice what you're missing, but once you have a better reference point it becomes immediately clear that there are delays on the S-PVA panels. That said, I've never had issues with the <20ms lag; it's only when you start getting above that where it becomes noticeable (for me).JonnyDough - Monday, January 30, 2012 - link
Agreed. Input lag is also a problem. Many gamers don't seem to notice these things, but I certainly do. Maybe we were just spoiled with CRT monitors from back in the day?Sabresiberian - Monday, January 30, 2012 - link
He did.The fact is, most people wouldn't be effected by this much lag, even in FPS gaming.
That being said, if you don't pay attention to the lag from each component of your system it could all add up to something that does effect your performance, so getting a monitor with lower lag can be a plus. However, if you really want lower lag in gaming, I suggest a CRT. Of course if you demand larger than 21" you can't really do that, but then I suggest gaming lag isn't your main concern, if that's the case.
(You also pretty much have to buy used, since they aren't made anymore. However, you can find CRT monitors with better quality than LCDs for less money.)

TN monitors are crap! I have one low end IPS display and I love it. It is perfect even for games! Oh, yeah, and I connect it to a laptop with ordinary TN display and do you know what? I hate looking at the laptop because of its crappy TN display!TN sucks! That's it! Get over it, losers!

Im waiting to replace my current IPS, but I wont take TN either.Why no display port too? Or 1200 lines? I want something to drop in the middle of my other 2 24" displays, so i can drive them in a big desktop, having one at 1080 is going to mess it all up.
Seems ill be waiting a long time.

In the last row of the table on page 1, should the price check be 1/24/2012, instead of 2011?cheinonen - Monday, January 30, 2012 - link
Sorry, fixed!demonbug - Monday, January 30, 2012 - link
On the power use chart, do the Apple Cinema Display and Dell U3011 really use more power at min. brightness than at max, or did they just get their numbers reversed?
