I received my Optoma Uhd60 about 2 weeks back and I am noticing that the projector is flickering on ECO mode and also on Dynamic Black mode. The flickering is getting worse day by day (light flickering dim to bright while screen is paused or slow frame). I tried multiple power sources to evaluate if it is unstable power provided to the unit but the flickering was still obvious. I also was told that keeping the lamp mode on BRIGHT for a few hours could help resolve the flicker but again after using the projector for 20 hours in BRIGHT mode when I switch back to ECO the flickering is still obvious. Is this a common issue?
Below is the summary of my setup:
HDMI cable is a DTEC 18gbps cable 50ft:?
Source is the Nvidia shield Pro, connected directly to the projector, no receiver is used.?
HDMI PORT I am connected to is the HDmi 2, which supports 18gbps.?
The lamp mode running on ECO power brightness is causing flickering, if I use BRIGHT power mode the flickering is not visible. I tried using DYNAMIC BLACK on both modes ECO and BRIGHT and the flickering is more severe and very obvious. The flickering starts very mildly then after 15 mins of use the flickering becomes more and more severe.?
I am currently only able to use the projector on BRIGHT lamp power mode with dynamic black mode switched Off.?
I have tried to resolve the flickering by doing the following:
- connecting to another power source / power socket
- keeping the projector on BRIGHT lamp mode for over 20 hours
- changing HDmi cable to a shorter length, from 50ft to 10ft.
All the above failed to resolve the issue.?Anyone else facing this issue?
