Changed out my Ultrex last week with my spare. Fired up both units on the front and the 360 had major inference went in and changed the noise filter to 2 and turned on the dynamic contrast it cleared it up it is still not as clear as it was before. The previous setting, I ran were 1 on the noise filter and the dynamic contrast was turned off. No issues with the other graph. Gen 4 for the 360 and the other one is a Gen 3. I never had this issue with the previous Ultrex
