I bought a 2017 Vizio M75-E1 last fall and put it in my barely used basement. I've started to actually do stuff with it in the last month and have noticed serious backlight and color inconsistencies that may or may not be normal, so I wanted to check with other owners or those familiar with these types of sets before I initiate any type of return or warranty repair. This TV is a LED backlit with multiple dimming zones (cannot remember how many, but not as many as the P-Series)
1) Solid colors look terrible and are inconsistent across the entire screen
2) When there is a contrasting color, especially with motion, I see a halo or ghosting effect around it. For example, moving white lettering on a black background will have a halo surrounding it, and it's always fluctuating
3) I get a random flicker about once every 60 seconds that lasts for less than a second. More like a random flash or artifact. This is only happening with HDMI sources on the 4K HDR Input
This thing was a nightmare to transport and get installed, so I keep hoping there's a software fix for this, but I wanted to check here to see if anyone was familiar with similar issues. I've never owned a local dimming LED set before (all plasma and edge lit before), so I'm not sure if the ghosting and backlight/color inconsistencies are just something that I need to live with. I purchased from Costco and have like another 5 years of coverage between the costco CC and squaretrade.
