Actually, 16:10 is the old standby and 16:9 is the upstart newcomer. I play on a 16:10 monitor and have never run into an issue with games supporting that resolution. Everything looks as it should. Pre-rendered cutscenes and such will usually have a small amount of letterboxing, but that's about it.
I'm sorry I didn't post before. It's been a crazy week, as I'm already buying the parts, and buying from the US and shipping to my country is kind of difficult task.
I've already bought most of the parts, and some are just one click away on Amazon to be bought.
Thanks mfenn for your opinion on 16:9 and 16:10 related to gaming. I've read as well that 16:10 is perfectly fine, just as 16:9 is for that purpose. So, no problem there.
Now, my final decision to complete my long-waited machine is about the monitor. One thing that is bothering me a lot is the warranty, because I've read many reviews complaining about dead or stuck pixels, or other issues on the displays. For me is quite difficult and expensive to make use of the warranty in the US living in my country. That's why I've decided to buy it locally, in order to get up to three-year warranties. To have that, I'm limited to Dell monitors, which end up being cheaper to get in comparison with bringing them from the US, and adding the bonus of local warranty it becomes a no-brainer.
Dell is doing great regarding IPS panels, which are the ones I'm definitely interested in. I want to experience that, coming from a TN panel fro a long time.
I've selected two models that I find quite interesting and with many positive reviews (with some cons, of course).
It's worth mentioning that in my country, the 27"-inch is around $90 more expensive than the U2412M.
I'd appreciate some guidance to select the best option.
Some reminders: I'll use it for gaming (hoping to get the best experience here), web surfing, movies and TV shows and web design.
Thanks for your help. ^_^
