What to choose between these 2

Hey there TS community. I have a dillema I want to discuss with y'all. I want to buy a new monitor, and I am stuck between this: http://www.pcgarage.ro/monitoare-led/benq/gl2460-24-inch-2ms-gtg-black/
and http://www.pcgarage.ro/monitoare-led/acer/g227hqlabid-215-inch-6ms-black/ , it's a romanian site but the specs are easily available. I know that IPS is much better than TN but the problem between these 2 monitors is that the TN has 2ms resp time and the IPS one has 6ms. Now I don't know how will that affect me, I want to buy a monitor that won't kill my eyes on the long run. I plan on using it inside not outside so no problems with sun strokes or anything like that.Also, having 2 laptops and 1 PC in my house, 1 laptop has a glossy screen, the other 2 have matte screens. Here's the thing, the eye strain is so much worse on those matte screens than on glossy even though people say it's the other way around... That would be a big problem for me too. But this is less important. What I want is a good screen that won't kill my eyes for some hours of use, be good for gaming since I do game (I don't game dota for hours or anything like that, I do some BF, CS, FPS, GTA 5, AC, and such so no rpg marathons).

I've come to the conclusion of the 2 models because of the price, that's it, otherwise I would have gone for a better choice but at double the price. Your suggestions would help me. I would like someone who has a good experience in monitors and panels, that's what I am looking for.

Regards

Nobody?

The BenQ without question.

21.5 screen is too small in my personal opinion. unless you have multiple monitors and you use that 21.5 inch in portrait mode. it would make sense. but the minimum you want to start with is the 24 inches. and the BenQ is just that. and is excellent for gaming with the high refresh rate.

If you want fast response times that eliminate motion blur for the cost of poor color reproduction, you could get the TN panel. But if true color is what you want (with some terrible backlight bleed) get the IPS, you get slower gtg response time which produces motion blur on fast moving images but is a wee bit easier on the eyes (at least that's what I believe). 2ms and 6ms is not that noticeable once your into the action anyway so I guess it's your choice what to get, but if I were to be asked what to get for myself, I'd be getting the IPS, I love colors.
Good luck on your quest for monitors and happy gaming. Cheers.
