The 23" display on the XL2370 takes on the increasingly popular 16:9 aspect ratio. Widescreen monitors used to be 16:10, but as high definition content and movies become more popular, monitor manufacturers are starting to adapt the 16:9 aspect ratio to fit those videos natively without any stretching. The XL2370 is capable of 1080P high definition playback at a resolution of 1920 x 1080.
I've read a lot of criticism over the use of a TN panel in the XL2370 versus the use of a PVA panel. For those who aren't familiar with the technology behind your monitor, the panel type can play a big role in the use of a monitor. TN panels are cheaper priced, have the fastest response times and are the most common panel type found in displays today. PVA panels are the only panel type able to display the true 16.7 million colours without using "enhancing" techniques, but at the cost of a higher priced panel. The majority of LED/LCD monitors in this size range and especially price range are TN panels. Now that you're a little better versed in the difference, make sure you don't take the critism about this too strongly. As you will see in my testing later, unless you're in a position where colour accuracy is absolutely crucial, then a TN panel will likely be just fine for you.
