Clarifying differences between TN and IPS [SOLVED] - Page 2

post #11 of 17
Considering your statements regarding contrast, I really think that it would be worthwhile to see if you can'tview a VA-type panel in pperso. The newer ones r eally look better than anything else, assuming that they have a good pixel density they practically look like photographs and not digital displays. The response time issues of old no longer are really applicable, with good to great clarity of motion.

Otherwise, AH-IPS is the way to go, and my personal favorite panel tech. It has better contrast, especially blacks, than older IPS types.

I cant find any AH-IPS monitors available in my region. The cheapest VA pannel I could find was the Dell S2440L, for $330 NZD, which is above what I was willing to spend, but I will see if anywhere nearby has one on display. Thanks for the suggestions smile.gif

UPDATE:
Called the local stores, and no one had the Dell on display, or any other VA monitor for that matter. Its kind of tricky for me to make up my mind regarding VA without seeing one in person, so I will have to keep looking.

I also asked a few of them about light bleed, which has been an issue before, and they said that typically a degree of light bleed would be present in all consumer grade monitors, and that you would be looking at $1000+ before you could eliminate this. I am curious if this is just relevant to new LED screens, as I own an older AOC 2436Vwh, which is a CFL screen if I am correct, and I literally cannot find any light bleed or glow or anything of the sort, even with a pitch black room and black image on the screen. Would you agree with their statement regarding light bleed? And/or are some panels more prone to it? I.e. TN vs IPS vs VA?

Ah, well it would appear I was mistaken then, I have been looking at monitors including the AOC monitors you mentioned, however they are marketed as "IPS", not "AH-IPS". All the monitors I am looking at are 23-24" IPS, so by your definition, I guess many of them are indeed AH-IPS, as I said though, they seem to me marketed as "IPS" instead.

It is interesting to see some of the monitors you mentioned, namely the AOC i2367fh and LG 23EA63V. After reviewing all monitors available within my price range in my region, I narrowed it down to 3 ips monitors. These were the AOC i2367fh, the LG 23EA63V-P, and the ASUS VS239HR.

I haven't dealt with LG before, and couldn't find many reviews on it, so I had for the most part ruled that out. Currently I am still finding it hard choosing between the other two. However after you have mentioned the 23EA53V, I might have a better look. It actually has some very appealing features, like both a thin bezel and wall mount, the AOC and ASUS monitors have one or the other. One of the thing that deterred me was the contrast ratio, which is as I have discussed, important to me. The figures LG gives are a little difficult for me to compare, they use DFC, LG Claims a DCR of 10,000,000:1, while AOC claims 5x this with their screen, and ASUS 8x this, at 80,000,000:1. Higher is better right? Is this difference big?. Furthermore, I have seen reviews commend the AOC and ASUS monitors for their colours, particularly the ASUS model, but saw no such feedback for the LG model. If you had any more information on the LG 23EA63V (which I assume the V-P version is based on), or infact the LG 23EA63V-P, then I would love to hear it.

Yes LG like to add various letters to the end of basic model codes. In this case the 23EA63V and 23EA63V-P are the same thing. The dynamic contrast ratios (DCR) are best ignored as they are calculated using undisclosed techniques and a specific 'dynamic contrast' mode that most users not only won't use but many will actively avoid. What makes contrast 'dynamic' is a shift in backlight brightness relative to the levels of 'light' and 'dark' on the scene. Monitors such as this have the whole backlight act as one single unit (BLU or Backlight Unit) so that the brightness can not be adjusted for individual zones or areas of the screen. Since images tend to be a complex mixture of light and dark and that the constant backlight brightness shifts can be at best slightly distracting, this isn't an experience that many people enjoy. The static contrast performance is very similar on all 23" AH-IPS models - 1000:1 is stated and usually roughly accurate. There is variation in uniformity, as mentioned previously, but the central value is usually around 1000:1.

There is a review in Russian on the 23EA63V (I would recommend using Google Chrome browser to automatically translate it all). This is a monitor I have used myself relatively briefly. Not long enough for a full review, but long enough to formulate a bit of an opinion. My experiences largely mirror the Overclockers.ru review. The colours are essentially very much comparable to the AOC i2369Vm in that they are rather well balanced out of the box and have a good rich look with the sort of shade variety you'd expect from AH-IPS. Input lag is not a problem at all, it's practically non-existent. Pixel responsiveness is one area where LG's own IPS monitors can sometimes fall short with settings that provide too little acceleration to really reduce trailing/ghosting as much as some users would like or too much acceleration so that obvious overshoot artifacts crop up. Fortunately the 23EA63V has a decent range of settings (a bit like AOC's models) with a 'Low' setting that is fairly similar to AOC's 'Weak' setting. I wouldn't say this is perfect as there are technically some overdrive artifacts but they are really rather weak and not something I would worry about or that you'd be likely to even notice really.

One issue to be aware of that some users have reported on the 23EA63V is a 'sharpness bug' where the sharpness level on the OSD resets to '6' every time the monitor is switched off. I'm not sure if later revisions have fixed this issue, but many users find '6' to be a bit too sharp and would have to change this setting manually each time they turn the monitor on.

Mmmm, I'm not sure that I will get an extra $70 benefit from the LG one. The wall mount AND narrow bezels are the main distinguishing factor, in reality all 3 monitors seem pretty equal. As for the ASUS one, that will be in stock in about a months time, it seems pretty nice, but still not sure if it will compare with the AOC one and be worth the extra $35 each. As you can probably tell I am swaying towards the AOC one, for a few reasons. For a start, its cheap, which my wallet likes very much. Second, I have actually had a chance to try one, and it was very nice, aside from some rather bad light bleed. If I can get a model without this light bleed, then I think I will go for that. Failing that, I will test my patience, if I can wait then I will wait for the ASUS monitor, otherwise I guess I will go for the LG one.

The only AOC display I've used in a long time is their 29" 21:9 model, which while an AH-IPS panel, is a whole different animal than the monitors you're looking at, so unfortunately I can't comment on them :/


As for LG vs Asus, I would tend to lean towards the former as they are the ones who actually make the panels, as opposed to Asus who buys panels and other parts and then assembles them. It's kinda like buying a Samsung vs Corsair/etc SSD; the latter is just a collection of misc parts put together by the "brand", so you're paying for someone else to put the Lego's together then stamp their name on it, while with the former, every single piece of the drive is manufactured by Samsung, so you know that it was all designed explicitly to work together and it isn't just a company's attempt to cash-in, but the result of tens and hundreds of millions of dollars in R&D....

I contacted a local supplier, and they let me go in and view a couple of the AOC I2367fh monitors before I bought them. In the shop I could notice a little bit of light bleed, similar to that I saw in previous models I had bought from another supplier, but I came to the conclusion it was only a bit, in extreme lighting conditions, at unusual angles. For the price offered, they were a great deal, they even gave me $10 off each of them, which was nice.

If I had any doubt about IPS vs TN, it was solved in the store. I was looking at a row of TN models they were displaying, and they all looked good, a few were noticeably worse than others, but they all looked more or less fine to me. Then I went around to the other side of the display, and among a row of TN screens, there was a lone IPS one, and wow. The colour difference between the IPS monitor and surrounding TN ones was huge! In comparison, the IPS was crystal clear, with bright, and vibrant colours. The TN monitors looked dull, ranging from a little to severely discolored at most viewing angles. Any doubt I had about TN or IPS was resolved then and there.

So I had another think about it. The AOC monitor was by far the cheapest, it looked nice, the colours seemed great. There was a little light bleed, but ultimately I decided this was worth it for the price range. The next option was either waiting at least a month, which would place the purchase a few weeks before my final exams, which is no good - it would only serve to distract me from studying, and it would cost an extra $60. After that, it was the LG monitor for an extra $80 at least, and it had the possible sharpness issue I was wary of. With that in mind I went ahead and bought the AOC monitors.

So far, no regrets, they offer good image quality, and while there is light bleed, its hardly noticeable - only at unusual view angles with extreme lighting conditions. If anything, some of the youtube videos I am watching suddenly a little over saturated, but that might just be me, or I still need to tune the colours. On the other hand, my games look great, some, like ARMA, used to look very bleached out and lifeless, but it now looks a whole lot better, with much more vibrant colours. Out of the box colours are fine, although tweaking them is a significant pain in the behind with the OCR buttons behind the screen. Build quality seems nice and sturdy, the panel seems a little delicate to me, but that's only because I'm use to a huge, heavy and fat cfl monitor. It is also a little annoying that the screens dont have inbuilt transformers, instead you plug a transformer into the mains and run a cable from that to the screen, but for the price, I'm not surprised/fussed. Nice contrast, no noticeable motion blur from the 5ms response time, all in all, a good monitor for a budget.
