Please note that this is not the K model. It only supports 120Hz on PS5; Xbox is not supported. I purchased this new about 5 years ago and have been using it ever since. It works without any problems. Everything is included, such as the stand. Please refrain from purchasing if you are concerned about use in an environment where electronic or paper cigarettes are used. I will clean everything before selling. Also, the original box is large, so I will ship it in the original box. 240Hz refresh rate BenQ DyAc™ technology Black eQualizer; Color Vibrance S Switch & Shield Hood
