What monitor for gtx 590 charged

ist better playing on bigger monitor 1920x1080 rez or 24 inc 1920x1200

The Dell UltraSharp U2412M has a response time of 8ms. A good gaming monitor should have 2ms or less to avoid ghosting. While 1920x1200 is a slightly higher resolution, if you are gaming the Viewsonic will be much better.

and ist bigger to  than i think Viewsonic ist my choise 
thanks

No problem  

i am reading that BenQ EW2730V ist good monitor...cost more but that have better coulours....but response time ist 8 ms

I would avoid BenQ's, I have heard not so good things about them...plus it's 8ms, it's not for gaming.

if you want the monitor for games then i would actually say neither. asus or samsung with 2ms and mega contrast is what i always go for.

There's nothing wrong with Viewsonic, I've used them in the past and they make great monitors. However, I just looked up the 27" 1ms Viewsonic the OP was talking about and it has no DVI input. If you are using HDMI then this isn't a problem, but just something to be aware of.

Here's a similar monitor by Asus, 27" 2ms LED backlit to consider also, that has DVI input: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The Dell is an IPS-LCD monitor. IPS monitors provide a much better viewing experience by offering more accurate color/contrast, and better viewing angles. These monitors are designed for graphic designers and professional photographers.

The Viewsonic is a TFT-LCD monitor, which are much cheaper and have faster response times than IPS-LCDs. The monitor you own now is likely an TFT-LCD.

Most gamers prefer TFT displays because they value faster response times more than they value image quality.

However, I argue that most gamers have never played on an IPS display before. If they had, they might not be so quick to dismiss a beautiful looking display (the Dell U2412M) in favor of a s*!t display with a 2ms response time. Furthermore, the response time on new IPS monitors pretty good, and should be good enough for most gamers.

Unless you are a professional FPS gamer, go with the Dell U2412M or U2410. Once you go IPS you can't go back

but i am only playing fps games 

what do you thing ....Samsung SyncMaster S27A750D LED...

Check this ASUS one out. I have it and it is pretty awesome. LED, 2ms response, HDMI and DVI. Also has decent speakers.

I use a Samsung Syncmaster, and it's a great looking monitor.

I can't comment on how the image quality and ghosting compares to an IPS monitor though since I've never used one before.
