It specifically says "1080p @ 60 fps". So is it a lazy web designer who copy pasted text about velocity mode and forgot to correct it or is it a manual author who did not pay attention to refresh rate when typing? I don't know. That's why we ask owners to verify these contradictions. Here is an owner saying it does not work Official 2015 Vizio 4K UHD M Series Thread
My reply was not about me being wrong, I know it was not the case. The reply was about you stating this was just based on speculation and that was 100% wrong.
I know about the manuals, I posted about them long time before your post HERE post #110 on April 6
., Thats when I first started to question if there is a 1080p@120 aupport. At that time I was not sure since some of Manuals shared models with 120 Hz Effective Refresh Rate and 240 Hz Effective Refresh Rate.
Based on that I first thought it might be mistake jn the manuals, so I decided to post a question at RTINGS
They reviewed one off the 2015 M-series model as 1080p@120hz. HERE
is the post and reply near bottom of the page;
Did you really tested the 1080p@120fps?
The M43-C1, M49-C1, M50-C1 & M55-C have 120Hz Effective Refresh Rate. The M60-C3, M70-C3, M65-C1, M75-C1 & M80-C3 have 240Hz Effective Refresh Rate.
In all the manuals, the HDMI port 5 High Velocity Mode is described in a note as: "Available for compatible gaming systems or high-performance PCs for display of 1080p @ 60 fps."
The P-series have the same port described as 1080p @ 120fps, except it does not work without getting black screen or game lockups, as reported by many in the AVS Forum P-series owners' thread, and also reported to Vizio suport. Vizio is promising to fix the bug with firmware update, yet seven months later they can't even give an ETA on that.
We did, by forcing 1080p120 with our GTX 960 graphics card. This is the photo we took of the test result, which shows there was no frame skipping.
We were also able to get 120 fps with our Vizio P, and likewise did not have any frame skipping while conducting the test (Photo here). Unfortunately, if this is a known issue and Vizio has promised a fix, there is nothing to do but wait.
