Can anyone point me to a good settings profile, specifically for gaming purposes, for the Vizio M55? I haven't noticed any motion blurring yet, at least to the point where it's clearly visible and affecting my experience, and that's with all motion blurring settings turned off to allow for minimal input lag.
I will say though that I'm starting to realize that 4K is still a pipe dream. There's a lot of work you need to do to view 4K content. For one, the YouTube app on the M series does not support, at least to my knowledge, the ability to view 4K videos. I was neither successful in viewing 4K content from the Amazon Prime app. When I finally created a UltraFlix account and logged into the app on my TV, the free content I was able to watch stuttered the entire time, meaning my Internet connection is clearly too slow.
So, without 4K content, is there any benefit in having a 4K TV? Does upscaling 1080p content really produce a better image? There's a lot of conflicting information about this across the web. Some sources claim yes, some claim no. Either way, it seems that a lot is sacrificed (input lag, motion handling, price, etc.) just to achieve the ability to view 4K content that you may or may not actually ever watch. For those reasons, I'm wondering if I would have been better off with a 1080p TV.
There was an earlier post in here claiming how the M60 exhibits less motion blurring over the M55 being as the former sports a 120 Hz panel but if all motion processing technologies are turned off in the interest of minimizing input lag, what benefit is there? See the following post from someone who purchased both models over at the AVS forums:
If you're buying a set purely for low latency console gaming at 60Hz, I don't think you will notice a significant difference going from the M55 to the M60 as you will want to keep GLL on. I tried a number of FPS games (Fallout 3 NV streaming from my PC via NVIDIA Shield, Bioshock and Tomb Raider on PS3 and Bioshock 2 directly from PC via HDMI), and while the motion looks noticeably better on the M60 with GLL OFF, there is too much lag between input and the screen to play effectively. Turning GLL on fixes the lag but also disables the motion handling advantage that the M60 has over the M55 with 60Hz input.
For my setup, I think I could have actually gotten away with the larger 60" size but it doesn't appear that I would have achieved much benefit from the 60", other than the larger size alone, based on my purposes. I still find myself sitting almost as close to the 55" as I did for my 40". Not sure if this is out of habit or because the 55" is still not big enough. Regardless, the 55" is a welcome jump from the 40" and everything I've played thus far felt much more immersive.
On a final note, is this normal? All four corners are noticeably brighter that the rest of the display. This is somewhat exaggerated by the poor IQ quality of my phone's camera but it's definitely there.
