Wonder if it has anything to do with the input being 2160/60? On my M70, using the non 2160/60 HDMI input for my firebox, never had any issues.
Need to experiment to see if it's a specific set of files - the video I was watching was 720p mkv
This will be a little long winded and possibly stream of consciousness but I'm gonna put it out there the best I can and just share my experience in case others are in a similar predicament with similar equipment and setup . I've had the P65-C1 since Thursday and have tried to test my current setup with this display. I am coming from a Samsung 52" LCD LN52A650 which was run as a PC display at [email protected]
4:4:4: 8bit, it's also an excellent television IMO. I really have to make a decision in the next week as to whether or not I want to return this TV or keep it and hope it's possible to work through some issues I've been having. I am mainly a PC user that watches content from my own media library on my HDD's from DVD's or Blu-rays I've ripped, YouTube content and some other video sites. I watch minimal cable content from DirecTV and I play games on a couple platforms, mainly being PC & PS4, some PS3 but to a lesser extent.
I'm using this as a PC monitor with Windows 7 and a GTX970 on HDMI-1 and HDMI-5 from dual HDMI outs on my Denon X4200W, no video processing applied. On HDMI-1 running at [email protected]
4:4:4 8bit (I couldn't not select a 10bit option in the NVIDIA program) and the colors are not bad. Everything is so tiny, and yes, I knew it would be but to visualize it and then try to use it, it's very difficult from 9 feet away. Not a knock on the display at all, just and observation. I haven't messed with any calibration aside from turning most features off, like judder and blur reduction, all noise reduction, just to see how it performed most raw. I never used any such features on the Sammy either. My complaints aren't with the looks of the display but in how the performance has been for me with the equipment I have.
When using the display for normal Windows use it is seems rough, movements of the mouse, dragging windows or other things, etc. Nothing seems really fluid when I compare it to my older TV. I'd have to imagine it's due to the larger resolution but I really don't know. My main gripe is in using KODI and MPC-HC as media players. I get stuttering/slow motion type of artifacts when playing movies that are 23.967fps, typically your blu-rays and such. Usually videos and movies will play fine for a minute or so, sometimes more, and then inevitably hit a point where the stutter/slow down, then it will rectify itself and repeat. This seems to happen in KODI more than MPC-HC as far as I can tell. Again, my setup is the same as it was with my old TV, which was nice and smooth, and the only thing really changing is the resolution, no? Up from 1080p to 2160p, same 60Hz, same 4:4:4 8bit. I'm also experiencing anomalies with the sound.
Within KODI I had a option "sync playback to display" (picture below) selected for my 1080p Sammy and the video and sound were fine, perfect. If I have that box checked in KODI with the Vizio the video will run fine but I get audio glitches and dropouts. If I uncheck it, it is the opposite, the audio is fine and the video gets stuttery at times. The option to "adjust display refresh rate" within KODI just makes a mess of everything, which I expected but I don't remember if I tested on my Samsung. MPC-HC seems to play files a little bit better but still with the same video issues and occasional audio issues. This makes me thing it could be a software related issue but I can't understand why it's happening with this TV. For me personally, whether it's the display, software, or a combination of both, I am not getting along with it on that front.
I'm not sure if people using PLEX have any of these issues but I really don't want to have to change my whole user experience if I don't have to. I've never used PLEX but I just don't see why it's not running fine with KODI and MPC-HC to some extent.
Playing blu-rays from the PS3 or PS4 seems fine to me. I don't get the issues above, but this isn't ideal for what I've created and immediately is the biggest deal breaker.
I used HDMI-5 for this at [email protected]
4:4:4 8bit with "game low latency" ON. I didn't play anything hard core but tested Crysis 3, Tomb Raider, and a couple others. I think it was pretty good for gaming, lag times seemed pretty good, fluid motion, nice detail. I really don't have any complaints there. Again though, I really only tested some games out and didn't have any extended sessions. YMMV
HDMI-5 again, pretty much the same as above. Games seemed to play pretty nice.
I haven't been totally impressed with the way satellite looks on this display. The Vizio doesn't do any favors upscaling the picture from 52" from 65". To my eyes it definitely looks worse than on my 52". Again, I didn't expect it to look amazing or anything but I did hope it would look a little better than it does. I'm not sure exactly how to describe what I'm seeing but maybe it's what people call ghosting. Like you're 22 again and at a Floyd show or something and you are catching trails off of objects and people because you ingested some sort of something lol, hey lighten up
While passing through 720p & 1080i from my STB I did try upscaling with my AVR both on and off and I like the picture better when the VIZIO did the heavy lifting. YMMV. I didn't notice it as much on my old panel as I do now and I suppose it could be attributed to the larger screen and resolution. I don't know. I know I don't like the SOE feature, which is "judder reduction". My old TV had this but only low, med, high & off. At least here you have a 10 point step and keeping it on 0-2 was not too distracting to me and even looked pretty decent. Even with this on though I still noticed this ghosting effect.
I watch 80-90% hockey on satellite and tennis as well. Once I saw the yellow band while watching hockey I can't unsee it, and it bothers me. If everything else on this TV worked for me the way I wanted it to I might overlook this, but it really just adds to the reasons I don't think this TV is for me yet.
I've had limited experience with actual 4K content. In fact, it's only limited to stuff that was on YouTube in 4K. I did this through the CASTING feature and on my PC directly off the YouTube website. Overall the results were much the same, the content I viewed looked really very good for what it was, better than 1080p for sure. I was quite impressed viewing all the 4K footage I could. I have the TV hardwired to ethernet but the ramp up time to get the 4K while casting was a bit hit and miss, it would take some time to enable it and then might lower resolution for a little bit and come back. I didn't really have this issue from the PC side. No movies in 4K for me, nor have I experienced DV yet. I just couldn't spend the money to demo 4K in DV when I was having those other issues I mentioned above.
I'm not totally sold on the tablet usage for controlling the TV but it is interesting. I like minimal display while making certain adjustments and I can see this could be a huge benefit if you are calibrating your set. It definitely has benefits but I just found it more involved than a standard remote, a little clunky. It does work though. I like it, but I'm also not entirely sold on it. The casting feature is very cool I think. If you subscribe to streaming services I can see this being really sweet, I don't have any at the moment.
In closing, I really want to love this TV. Can someone tell me why I should keep it? Is none of this the TV's fault? Are any of you PC users experiencing similar issues as I am? I'm curious to hear about them. I don't want to return this TV but I feel I might have to. I also know there are a lot of people who seem to love the TV but might also not have the same type of media configuration as I do, so I understand this. Just interested to hear from the masses out there.
