I have one of the recent versions of the X108G Outdoor, I think with the OLED rather than LCD display. I have problems being able to read it in any level of sunlight. I have checked in the advanced menu and brightness is set to 100% but the option to adjust contrast shown in the manual simply isn't in the menu. This could be as an OLED is considered high contrast. Adjusting the brightness value in the menu down to 30% has no effect on the brightness. I have sent an email to Xiegu with no response so far. Has anyone else seen the same problem - no way to adjust the display on the OLED equipped X108Gs ? 73 Ed DD5LP.
