A:AnswerHi QuestionMAAAAAAAAAAN, Thanks for your inquiry. The X800H is an IPS panel type which are designed for wide viewing angles so you should expect a great viewing angle on this TV from left to right. If you are mounting the TV high and you are looking up at it I would recommend a tilt mount to allow the best picture from below.-Sam

A:AnswerFor this monitor, all HDMI inputs are 2.0.
Be careful when buying TVs that claim they support HDMI 2.1. There are many parts to the 2.1 spec and manufacturers choose to support some of the full feature set, but not all. They still sell the TV as a HDMI 2.1 capable set. This is generally ok as some features of 2.1 are needed for gaming but not for watching video. Another thing they do is one HDMI input supports 2.1 but the others are 2.0. It is up to you to research and find out. www.rtings.com is a great review site and gives a ton of technical information.
