So I've had my Oppo-203 for about 6 months now. I've never really had any issues with it. A little while ago when I bought my first Dolby Vision 4K Blu-Ray it was great, the movie looked good on my OLED, but there was one problem. Whenever I go for a break and the screensaver appears it presents a grey-ish black in the background. This only happens with DV discs. I've never had this problem with any HDR10 disc which display in perfect OLED black along with the OPPO logo floating around nicely. Anyone else had this issue?
