I was playing video games on a friends’ Samsung LCD TV. The contrast was too dark, so we adjusted the picture settings. After about every 10 minutes or so, the picture would just go right back to the same settings it had before we changed them. It wouldn’t save the contrast or brightness settings.
This appears to be a common issue where the television is in “Shop Mode“. Shop Mode is a type of mode that is used for televisions that are on display in a retail store. You will need to get it out of Shop Mode and put the TV in Home/Dynamic Mode in order for it to save the picture settings. Try these steps.
- On the television, push the “Volume Up” button once then let go.
- Now from the remote control, press and hold the “Menu” button for about 10 seconds.
- When the screen flashes, you should see an area where it will say “Dynamic mode“. On some models, you may have to press “Tools” and set “Demo” to “Off“.
But that didn’t work for me!
Some models such as the HW-M550 require these steps instead:
With the TV powered off, press and hold “Volume Down” on the TV until the words “SHOP OFF” appear on the screen.

My brand new 2020 model Samsung Q70 75inch TV keeps reverting back to ‘standard’ picture mode. No matter how many times I change it to ‘movie’…
The shop/home mode is an option directly in the settings so that’s changed to home, so it’s not that?
Tried everything.

I had the same issue and was able to resolve it by turning off eco mode, specifically the eco sensor, which was resetting brightness and contrast based on the light in the room.

I’ve tried all of the above on my 75” 4K Samsung TV and nothing works. In Picture mode always goes back to Contrast at 100. I’ve owned the tv for maybe 5 years, this is the second time this has happened.

This TV came to us used from a family member. It has worked fine for for the past 3 or 4 months but suddenly the picture is too large for the screen. I have tried to reset it via the standard fixes using the remote and on-screen instructions. Nothing seems to work, including the suggestion above.
Suggestions?

This didn’t work for me, but the instructions on this webpage did: https://www.samsung.com/in/support/tv-audio-video/why-samsung-tv-settings-changes-automatically/

This is a joke. I have a $2500 tv that changes backlight and contrast to max every few minutes and a $150 Vizio that seems to work just fine. Yay Samsung
