Reported aﬀected models: Panasonic Ex700 and EX750
Problem: There is an issue with pink hue overlay when TV has been in suspended or sleep overnight and then is turned on.
In some cases it is enough to do a routing change to fix this issue temporarily.
To reproduce the issue, we used a 1080p apple tv. Switch off the TV using remote for 3-5 mins then power on.
We tried all the combinations of HDR and mode setting and found that HDMI HDR Setting -on and HDMI Auto Setting - Mode 1 seems to stop this from happening.
Other settings we have on our tv but not sure if they make a difference:
Tested using HDMI 1
HDMI Content type- Graphics
HDMI EOTF Type – Auto
HDMI RGB Range - Auto
Off Timer- Off
Auto Standby- Off
No signal Power off – Off
One fix is to turn off HDR settings.
Go into "menu"
select "Setup" tab
- scroll down until you see "HDMI HDR setting"
- turn off.
In the description of this settings it is even stated "If the picture does not look normal, then turn off this setting"
