AOC i2353Ph - IPS for a nice, low price
by Chris Heinonen on January 30, 2012 12:40 AM ESTGaming and Power Use
IPS has never been the first choice for people when it comes to gaming due to slower reponse times than a TN display, but some recent eIPS panels have done a better job at bringing these numbers down. With the AOC, I saw just over 15ms of lag, which is just about 1 frame of lag at 60Hz. In my general gaming use I had no issues with this, but people that are very serious and want as little lag as possible will likely have to look elsewhere.
Finally we take a look at the power usage for the AOC using our Kill-a-Watt meter and with the backlight at both maximum and minimum values. The numbers for the AOC line up with previous eIPS panels of the same size well, which is what we expect to see. The peak power usage compared to the Dell U2311 is less, but since the peak light output level is also lower, that is not a surprise at all. The light output at the minimum backlight level is also lower, yet the power use is the same, so the AOC seems to be not quite as efficient as the Dell.

Yah one of my screens is a 27" 16:9, and I'd say from that experience I'd hate to have a smaller screen with that format. I bought the screen in part to see if 16:9 would bug me, and it does. Unfortunately, 16:10 in that size screen would mean going to 30", and the pixel pitch is significantly larger in current 2560x1600 displays than screens like mine that are 2560x1440.There are still 16:10 screens around (of course all 30" screens, that I'm aware of, are 16:10), and even new ones have come out; the format is far from dead. Generally though they are more expensive. I think the price increase is well worth it, and if people would stop buying cheaper 16:9 screens, then maybe the manufacturers would pay more attention to 16:10.
Laptop screens are the worst, these days. 16:9 is in my opinion, atrocious on them, and part of the reason I want 17" on a laptop is because of that format.

This comes up every review, but I feel the need to comment regardless. 16:10 panels will still exist, but they're going to continue to be a niche market. With 16:9 LCD panels, that enables manufacturers to use them for computers, laptops, and TVs. This leads to larger yields, lower prices, and cheaper panels for everyone. I also prefer 16:10 instead of 16:9, but that 16:10 panel can often cost twice as much as the 16:9 and makes the value proposition of it much lower for most people. For my laptop (Macbook Air, 16x9 ratio) I've wound up moving the dock to the side of the screen to save vertical space, and if I had a Windows machine with a 16x9 ratio I would probably do the same.I like 16:10 but I also realize that most people I know would rather pay half as much for a 16:9 screen, or buy two, than have that extra bit of screen at the bottom, and due to the manufacturing economics, I don't expect this to change soon.

I agree with cheinonen....I've ended moving the dock to the left side on my Windows 7 machine. It just makes better sense for me with the 16:9 screens.

I saw a samsung LED TN panel the other week, and the color reproduction looked phenomenal! is IPS irrelevent these days with OLED just around the corner? If they have'nt picked up by now, i imagine OLED will completely make them obsolete.cheinonen - Monday, January 30, 2012 - link
OLED is likely coming out later this year for home theater displays, but since that will be around $8,000 for a 55" display, affordable desktop displays are not going to be coming anytime soon. Perhaps in half a decade we will see them, but for the moment it's a technology with low yields, but very high performance, that will mostly be sold as a high margin home theater device I imagine. There is a lot that can still be done to improve desktop LCDs before OLED comes (such as backlit LEDs instead of edge lit, and RGB LEDs like the HP DreamColor display to provide true 30-bit color displays instead of 24-bit), and OLED might start to put pressure on vendors that can't produce it (only Samsung and LG at the moment can make OLED sets) that will need to keep up.IPS certainly isn't dead just because of TN with LED backlights. You still have the issues of TN (worse color fidelity, poor viewing angles), though the new 120Hz TN displays are very nice for gaming. With eIPS closing the price gap, it wouldn't surprise me if eIPS takes over the budget, general purpose display area and 120Hz TN takes over for gaming.

Tomshardware did a test of several TN panels in this price range (under $200) and the conclusion was - yuck.I doubt there's any under-$200 TN screen that comes anywhere near close to the quality of this thing.

Your Input Lag numbers looks funny.check out the Dell U2312HM 0.6ms average lag..

I rather get my Monitor reviews from there. no offense. For most things your the best!
cheinonen - Monday, January 30, 2012 - link
Is there another aspect besides the lag numbers that you would like to see improved? We haven't reviewed the Dell U2312HM that you linked to, so comparing any of our lag numbers to those would be an invalid comparison. We did review the Dell U2311H, and our lag was 8ms, compared to their finding of 10ms, so very close results. I'm working on finding a better way to measure lag, as it's one of the harder things to test I find.Thanks for reading.

@cheinonenOh thanks for noticing my comment. I only linked the Dell U2312HM to show that some e-IPS can be fine for "hard core" gaming since there was some general complaining going on about lag on e-IPS being no good for gaming.
As far as monitor review improvements, Maybe Pixel responsiveness, ghosting and motion blur comparisons. How do Movies look ? how about really dark scenes? That is all i can think of .
cheinonen - Monday, January 30, 2012 - link
I'm working on something for motion blur, but that might still be a bit further away. Pixel responsiveness will come into play there as well, as the more responsive the pixels, the less blur will be visible. Of course lag can still exist even with improved pixel response time, but that's why I'd like to be able to measure all of them.I will look into finding some good shadow detail material for movie testing going forward, but those are also very subjective as well. I'd prefer to be able to produce a test chart that measures gray swatches from 0-32 or so, which we can then chart compared to the 2.2 gamma we are targeting. Calibrating the grayscale at levels that low can be troublesome, as meters have more and more trouble reading values that low, but we can measure the gamma reasonably well with the i1Display Pro, which has more impact on shadow detail anyway.
