Christina is looking to get a huge gaming monitor for her nephew. HP or LG 24"? Leo says that it depends on how great an Aunt she wants to be. HP and LG both make videos that are curved and are very popular with gamers. Even some as large as 39". So it doesn't really matter which brand she gets. 24" is a little small, but if the kid likes that size, either would be fine. The key is what refresh rate it has, 120 Hz is good for gaming. And if it's listed as a gaming monitor, it will. And they aren't expensive at $175. The 29" LG is also very popular. $225
Where can she get them? Leo says that Amazon.com is the best option. They'll ship it right to him. NewEgg.com is another option, very popular with geeks and gamers.
