As expected, there is added support for HDR10 in HDMI1 – 4. HDMI 5 does not support HDR10.
We test this with various window sizes, sending an HDR10 signal. Local dimming is enabled for this test. Previously published results (before the update and using Dolby Vision) are included in brackets.
2% peak: 317 nits (312)
2% sustained: 317 nits (312)
10% peak: 440 nits (437)
10% sustained: 440 nits (437)
25% peak: 491 nits (490)
25% sustained: 491 nits (490)
50% peak: 522 nits (530)
50% sustained: 522 nits (530)
100% peak: 535 nits (546)
100% sustained: 535 nits (546)
The peak brightness is almost exactly the same before and after the update.
We tested the input lag using the Leo Bodnar tool. This was done at 1080p @ 60Hz. For HDMI 1-4 we also used the HDFury Integral to inject HDR metadata to see if this had any impact on the input lag when in a HDR picture mode. We compared with and without the integral, and found it did not any additional time to our input lag measurements (<0.1ms). There has also been some discussion about whether Active LED adds input lag, so we tested for this also.
HDMI 1, 1080p @ 60Hz HDR10
Active LED on, Game low latency off: 157.2ms
Active LED off, Game low latency off: 154.5ms
Active LED on, Game low latency on: 65.2ms
Active LED off, Game low latency on: 62.1ms
HDMI 1, 1080p @ 60Hz SDR
Active LED on, Game low latency off: 113.0ms
Active LED off, Game low latency off: 112.4ms
Active LED on, Game low latency on: 38.0ms
Active LED off, Game low latency on: 37.2ms
HDMI 5, 1080p @ 60Hz SDR
Active LED on, Game low latency off: 94.6ms
Active LED off, Game low latency off: 94.3ms
Active LED on, Game low latency on: 19.7ms
Active LED off, Game low latency on: 19.1ms
In our experience, sending an HDR signal did increase the input lag (by 25 to 45ms) but it's still okay for most people. We haven't tested other TV's input lag with HDR so can't compare it. Active LED also increases the input lag, but this isn't noticeable.
We measured the color gamut sending a 4k @ 60 Hz @ HDR signal. Previously published results (before the update and using Dolby Vision) are included in brackets. An image of the gamut is attached below.
DCI P3 xy: 82.53 % (81.49 %)
DCI P3 uv: 90.12 % (88.69 %)
Rec 2020 xy: 61.72 % (60.92 %)
Rec 2020 uv: 69.21 % (68.55 %)
This is basically the same wide color gamut as before the update (under 5% difference is considered not noticeable).
We tested for chroma 4:4:4 at a range of resolutions and refresh rates. To send 4k @ 60Hz @ 4:4:4 on HDMI 1-4 enable HDMI Color Subsampling. Only 4k @ 60Hz @ 4:2:0 is supported on HDMI 5. We took a macro image of the pixels to more accurately compare to a TV which displays 4:4:4. Images for the following are attached below.
4k @ 60Hz @ 4:4:4 – HDMI 1 (HDMI color subsampling necessary)4k @ 30Hz @ 4:4:4 – HDMI 1
4k @ 30Hz @ 4:4:4 – HDMI 5
1080p @ 120Hz @ 4:4:4 – HDMI 1
1080p @ 120Hz @ 4:4:4 – HDMI 5
1080p @ 60Hz @ 4:4:4 – HDMI 1
1080p @ 60Hz @ 4:4:4 – HDMI 5
1080p @ 30Hz @ 4:4:4 – HDMI 1
1080p @ 30Hz @ 4:4:4 – HDMI 5
We don't consider any of these 4:4:4 images a pass.
Let me know if you find anything we’ve missed, or if we've made a mistake somewhere.
When HDR games become available next month, you are figuring around 65-75ms Inout Lag while playing HDR Xbox One S? That will make this P65 unplayable for competitive gamers.
Also, so the KS8000 with clear 4:4:[email protected]
60hz is the way to go for competive gamers compared to the P65?
I'm a Competitve gamer and play Halo 5 HCS, and currently Rainbow Six Siege. I own the P65-C1 and a Benq RL2755HM.. The P65 with GLL and Clear Action On, And Active Led On Input Lag has been fine so far, Zero complaints.. Hopefully next month with HDR Games Matt McRae and the Vizio Team and figure out how to keep the Input Lag the same when HDR games come out, and eliminate unessesary processing from the set. Because 75m Input Lag Is Virtually Unplayable.
