    The LG OLED G5 sets standards with its new screen - it doesn't get any better than this at the moment. The OLED C5 is less brilliant, but otherwise practically just as good. Both offer audible sound with good setting options, as well as a full range of features and simple operation with many aids. So should you go for the cheaper C5? The G5 looks better on the wall.
