Solving playback issues

[JK48]

I have LG 65'' Class 4K UHD Smart LED HDR TV and recently purchased a roku stick+. 

I had google chromcast before and all the apps were fine and smart TV apps looked fine as well.

But when I used Roku stick+, all the apps had really bad contrast where all the bright colors were washed out and dark colors were too dark.

I can't seem to find the solution.....

Any help would be appreciated.

@JK48-

Roku menu path Settings > Display type.

Try experimenting with different settings.

When you change the Display type to a new setting it runs you through several screens:

• A screen where you can choose from the available options on that device.
• A screen where it analyzes your choice to be sure your tv supports it, then gives the option of trying that choice if you wish.
• A screen with a countdown timer and two choices:
      Yes, screen looks good
      No, I will choose a different setting
  The "No" option is highlighted by default. To keep the screen setting you're currently trying, you need to arrow up to the "Yes" option and click on it before the timer runs out.

Thank you for your reply.

But I've already tried those and didn't help.

Will try again and will let you know if somehow it changes its mind 😃

Another thought..

On many TVs the picture control settings on the TV are independently saved for each of the TV's inputs.  Have you tried adjusting on the TV?  If you are using the same HDMI port as the Chromecast device you mentioned, perhaps it needs to be readjusted for the Roku.

But i didn't need to readjust Chromecast, but I'll see if i can independently save the settings. Thank you
