pc configuration
CPU: i7-8700K
Mother: asus rog maximus x code
Grabo: asus gtx 1060 - dc 2 o 6 g
Memory: crucial ddr 4 pc 4 - 21 300 8 g x 2
m2: wds 500 g 2 x 0 c
Power supply: antec neo eco gold 550 w
OS: windows10pro64bit

If you play this movie with this monitor, the dark part will become full of block noise.
I tried both DP and HDMI connections.
Driver update, windows HDR set up.
On other monitors it is not 4k, but it normally appears.
Connecting on-board without using Grabo was also unchanged.
Is not there something you forget?
I would be pleased if someone can give you a professor.
Thank you.

It does not start to not verify variously oneself.

① Check the resolution of the monitor. (I try to 2K)
② Turn off the HDR function and check.

Do you know what it is?
Beyond what Slender thinks ...
The 4K resolution will be heavily burdened by grabbing and CPU.

③ Grabo + When the screen is disturbed + CPU usage & temperature checked.

It may be that HDR is also not being able to cope well with relatively new technology?

If you do carry out ① and ② without hesitation, if the display is decent, will PC be the cause?
Still it seems to be disturbed Initial failure?

It seems like a movie of a game when seeing an image?

As I said, the game at 4 K is around 1060, teeth will not stand.
Currently high power 1080 Ti is not enough power.

What is the source of the video (movie) used for playback?
Results may change when you try to play back movie files such as H264 or H265, which is based on streaming distribution using video distribution sites.
If it is due to the playback of self-shot movies, it may be a camera mode selection or other factors.


In addition, if you check the setting on the monitor side and you are using a mode to raise the resolution or using a forced double speed, that may be the cause.

Thank you for pointing out.

① Check the resolution of the monitor. (I try to 2K)
There was no change.
I see in the same way.

② Turn off the HDR function and check.
There was no change.
Maybe 4K is not the cause because it reflects the same way?

③ Grabo + When the screen is disturbed + CPU usage & temperature checked.
Grabo utilization rate Gaming mode GPUSPEED 104% GPU utilization rate 30 to 98% Memory usage rate 30 to 48%, temperature around 50 ° C

Because it exchanges the monitor itself with a new item of the same item, it is not thought that it is an initial malfunction.
I also doubt the grab breakdown Although I exchanged the same thing for a new article, I am without a symptom change.

Results In the form of denying the title, I apologize to all of you for your kindness.

Noise entered even during normal time and at 4K.

I am ashamed as I do not know the cause.

Thank you for the information.

Try out other videos that are not streaming delivery.

> When I went as I pointed out to Kinchan 1234, as I heard the noise even if 4K or 2K cut HDR
There was no cause due to 4K in the title.

Sorry.

It is as long as it is embarrassing.

There is no load at all.

> Woom210

GPU usage rate 98%

Grabo is the limit.

It is strangely incompetent if it is set to 1060 ~
What kind of browser do you use?

For the time being, I tried watching 4K movies with fire fox but (~ 2 screen on full screen on 4K monitor, monitor software on the other screen)
In my environment Grabo is at most 12 to 3%
The CPU also goes MAX core clock, but the usage rate is 10% so much.

There is no load at all.

Why do not you change your browser?

I noticed at this moment, though.
Perhaps PC is wired and not connected to the internet?

Is not it severe to see a high quality YouTube with a wireless connection?
I have set up all six PCs for wired connection, Iphone only wireless connection settings.

The browser uses Google Chrome.

I tried fire fox, but it did not improve.
You still can not ask 4K for the 1060 level.
I will consider purchasing 1080 ti.

Refresh rate can not be raised up to 60 Hz and it is 59 Hz.

Internet connection is connected by wired.
Line should also be stable with optical line and speed.


Thank you for much information.

The title and the content have been different, so I will resolve it.

Sorry to reply to resolved Sorry.

Is not it a mach band, not a block noise, a phenomenon you saw?
Us Mach band. Occurs when playing HORIZON with this monitor and PS4PRO.

PS4PRO is connected with the new PSVR unit in between, the cable comes with monitor included HDMI,
When setting HDR on with software side setting of HORIZON, the light source around the light source where there is a light source at night,
It occurs in the dark starry sky portion of the starry sky scene where the moon can see.
Even if you switch HDR NORMAL or DisplayHDR 400 with monitor setting, change various settings, reset
It did not solve it.
Also, switching color RGB or YUV with PS4PRO side setting was useless.

In the case of HDR display, it may be difficult to see a dark place considerably, so turn on HDR with software setting
Playing is about to give up.

Sorry for not solving information.
The possibility that it is not block noise, that it is not a phenomenon of PC alone, that things that Grabo can not be attributed to
I wanted to tell you, I replied.

I see, it is not block noise no matter how it looks ~

Do you have any Mach bands?
It was first look.

Many things come out as technology progresses.
One thing got better.

Thank you for the valuable information.

It is a phenomenon called block noise as it is not a Mach band.
This phenomenon occurred just in the light and dark split.
I am sorry for ignorance.

We also tested the same movie on this monitor with PS4PRO, MACBOOK PRO (A 1398) via HDMI connection, and Mach bands are still out.
It was the same with HORIZON.
On other monitors (LG 27 inches, MAC) it is not out.
Furthermore, even if Toshiba REGZA 55 X 910 and 49 B Z 710 X also verified the video from the personal computer via the HDMI connection, it will appear cleanly without problems.
Although it is not powerful, I feel that this monitor relationship is not due to a malfunction of Grabo.


It seems that it does not go well just with the new standards.
Since I also look quite rough, it seems to be a feeling to use movies and games with TV as they are divided.
It became quite helpful by having the same monitor.
Thank you very much.

It seems that I was convinced.
What I was interested in was ~

Toshiba REGZA 55X910 and 49BZ710X also verify the movie from the personal computer with HDMI connection and it will be beautifully reflected without problems.
↑
Here it is.

I adopted the 4K resolution relatively quickly for PC monitors for games ...
TV · · · It is the main policy to watch a video by connecting with a PC that does not see in real time first (just watch what you liked).
So,
TV is not interested in 4K, 32 inch (with double speed function) and 48 inch curved TV are both 2K resolution. (PC room is 32 inches, bedroom is 48 inches)

Even the same 4K resolution does not come out on Toshiba's TV, does it come out with Philips?
I see

I think that such information can not be obtained with thread such as TV.
After all I am making a monitor as well with a professional manufacturer of household electrical appliances The difference of the technical skill of the manufacturers'
I thought it was a fuss that it was out.

Although it is a serpent, I am using double speed complementary software
