So a few days (or weeks? I'm not sure) I posted the news of a 4K TN monitor from Asus that looked decent enough. And now Tom's Hardware has reviewed it.

The veredict is that it is still a TN panel with the color shift that this kind of panels have, but besides that, it's a good monitor that's will serve you good if you want to play with it.
Please excuse my bad English.
