On IPS, the colors won't change when looking at the screen at various angles. If you sit in front of the screen and it's filled with some uniform gray for example, that gray color will not change from top to bottom. IPS has problems in the dark. If you look at it at an angle, you see the backlight shine through. If you move your head, this glow moves around. IPS is great for daylight and lit rooms. This particular IPS monitor also has a matte antiglare coating which you might like or dislike, also something good for use in a lit room to suppress things being mirrored in the screen. On TN, the colors can change a good bit when looking at the screen at an angle. If you have a uniform gray picture in front of you, it won't be a uniform gray, you will see some sort of gradient from top to bottom of the screen. That gradient will change if you move your head. On the other hand, TN does not have that backlight glow problem. It might be better if you like sitting in a dark room and if you don't care about colors changing somewhat depending on angle. This monitor also mentions it has an antiglare coating, so perhaps no difference here to the other monitor. It's not one of those fast 120Hz monitors, has the same 60Hz limit as the IPS monitor. What monitor do you have currently? Do you already know what TN looks like or what IPS looks like? Is your monitor already great for something in particular, for example a fast monitor for gaming? Will you use only this new monitor or will you maybe use this one as a second monitor for work stuff? [I might be somewhat wrong about what current TN monitors can do.] Here's the TL monitor thread and the first post can maybe help you understand more about IPS vs. TN: http://www.teamliquid.net/forum/tech-support/308280-teamliquid-monitor-thread | ||

You can't know for sure without measurements or tests of the monitors specifically (specs are always various degrees of wrong). It's AOC E2752VH and I2757FH. The former uses a TN panel (most common in cheap monitors; if you don't know what you have currently, it's probably this), while the latter uses IPS. I have no idea what AOC's naming conventions and letters mean, but the I2757FH might be similar to the d2757PH reviewed reasonably in depth here: http://www.prad.de/new/monitore/test/2013/test-aoc-d2757ph.html So the E2752VH has higher max brightness, which is useless unless you're using in a very bright room and actually using near 100% brightness. Most people would set a brightness level that both monitors can achieve. It also has a VESA mount, whereas the other doesn't, which means you could use an aftermarket wall mount or stand if you wanted. Note that both monitors are relatively cheap and don't even have height adjustment, so maybe that is a legitimate factor to consider. The response time is lower, meaning that the time it takes for the pixels to change color from one to another is generally lower. In effect, for fast action and things moving across the screen, you get a little lower motion blurring. However, both are just 60 Hz displays, and the images (aside from the pixel transition times) stay lit and don't change between refreshes, so both have this common limitation in terms of motion performance for games anyway, like almost every computer monitor out there. So I wouldn't want to overstate the difference between the two in terms of motion performance. The I2757FH should have much better color consistency and less shifting of colors due to the angle on which you are looking at it. The whole 170 / 160 vs. 178 / 178 viewing angle thing is silly, as you probably wouldn't try to use the monitor at extreme ranges. However, note that the angle between your eye and the top of the screen is different than the angle between your eye and the bottom of the screen, so how the image shifts still does matter even if you're looking straight on. For larger monitors like 27", unless you compensate by viewing from far away, there will be a greater difference in the viewing angle. The bezel around the I2757FH is small, but the image doesn't go to the edge. However, that could still look less clunky and take less space than the other monitor. Both are cheap and probably don't do much processing and so should have minimal display latency. Both have included speakers that probably suck, and both seem to list 16.7 million colors and probably have a 6 bits + FRC implementation and roughly cover standard sRGB color space. The listed dynamic contrast ratios are silly and not realistic; actual contrast ratios are probably different but not all that far off, but it's hard to say which would be better. So if you want to be sure to eke out slightly better motion responsiveness for twitch gaming, the first one would be better. For overall better image quality in general for everything, choose the latter. | ||

I have minimal knowledge of related physiology, but anecdotally and from some kind of common knowledge that may not be correct, it seems people's eye strain is influenced or caused by the following things, among others, aside from usage obviously: 1. brightness too high — you can set both to be the same within a certain range 2. images too small / viewing distance — both are same size and resolution 3. reflections on the screen / glare — both have antiglare coatings, though possibly to different degrees 4. position of screen forcing eyes to need to constantly look too far up or down or to the side — limited adjustments on both monitors for positioning on desk 5. low contrast — would need review, but both probably similar (though some say high contrast causes eye strain and cite maybe viewing printed paper? I really don't even) 6. blue or other color tint, especially at night — who knows, would need review, but no reason to suspect one over the other, and this can be changed in software anyway 7. backlight pulsing for brightness control — would need review, but no reason to suspect one over the other Not everyone is affected the same way. | ||

I run my monitor at 25% for example, which is probably around 100 CD/m² according to a review about my monitor on that prad.de website. I'd imagine you would run into problems on a monitor where you can't see details in the dark areas in games anymore, making a low brightness setting unusable. I don't know how to judge the two monitors regarding that. I bet the IPS would behave better? I'd also recommend to not sit in a totally dark room, instead have the environment in your view lit to something that feels somewhat similar to what you see on the screen. At least that's what I learned about how my eyes behave regarding eye strain. Sitting in a lit room could mean that you won't notice that light glow downside that IPS monitors have in the dark so it won't be worse than the TN. Another thing about physiology is that you naturally won't blink as often in situations where you are stressed and concentrating. It's some sort of fight response the body has. Your eyes will hurt from being unusually dry. All this stuff about low brightness settings and lit room might be a totally broken idea I have and my eye strain problems being fixed might just have happened by itself. | ||
