I realize this monitor is an older model, but I have a guy that wants to sell me one for $50 and it's in great condition. Is this still a good monitor to use? It will mainly just be used for a secondary gaming rig I'm building for my son so he's not using mine. He is only playing games like Lego games and Minecraft, but from the specs, this still seems like a decent monitor, especially for $50. Thoughts or suggestions?
