Please provide the following information so we can try to help.
For example, what is the make and mode of the display you are using? Are you using any adapters or dongles? Etc.
1. I don't use adapters. Connect the monitor directly via HDMI cable 2.0.
2. Режим дисплея 3840x2160 @ 60Hz
Output device image Samsung UE40F7000
Driver version 16.7.2 Crimson
Operating system, Windows 10 64
reset bios Motherboard removing battery.
It did not help.
The TV going black for a few seconds randomly would normally be caused by a faulty HDMI cable as could the none detection of the display.
A single RX 480 would be roughly 30 - 40% faster (possibly more in some titles) than a 7970 card in none CPU limited situations depending on the particular game and resolution etc.
Also, check Windows Device Manager. My DP 1.2 4K FS panel started doing the same, turns out it had become disabled in Device Manager.
I probably incorrectly expressed.
On the same computer with the same graphics settings in the game and with a resolution of 3840x2160.
One receiver 480 will be about 20 - 40% slower in some games:
RX 480 8Gb
In the game "Lichdom Battlemage" the drop in FPS to 10
In the game "Archeage" drop FPS to 22
3Dmark-11 to 17600
In the game "Lichdom Battlemage" the drop in FPS to 14
In the game "Archeage" drop FPS to 25
3Dmark-11 to 9650
I believe that the decreased performance from RX480 caused by the drivers because during the game the GPU do not rise above 935 Mhz. The stated frequency of 1260 Mhz. (apparently an attempt in the driver to solve the problem of power through the PCI-Express 16X). And only in the benchmarks results are good. Very sad.
What temperatures is the GPU running at while playing games? Have you changed any settings in Wattman?
"Have you changed any settings in Wattman?"
Settings were not changed, as it is by default.
"What temperatures is the GPU running at while playing games? "
Maximum GPU temperature (81-83)C

I tried Lichdom battlemage at 3840 x 2160 resolution and I get 17 - 22fps with a single RX 480 and 27 - 38fps if I use two in Crossfire.
For the same game at 1080P its 60fps for a single RX 480 GPU and 120fps in Crossfire (on average)
So the game seems to be working at a fps I would expect. That is tested at the highest ingame settings, Vsync disabled. TressFX disabled.
Archeage runs at 32 - 45FPS at 4K, Vsync off. DX11 renderer on a single GPU, 60 - 85FPS if I use Crossfire (game doesn't have a Crossfire profile)
Tested on Win 10 X64 with 16.7.2 drivers using i7 6700K.
For lots of games you really need 2 GPUs for 4K gaming regardless of if they are AMD or Nvidia GPUs.
I also found that the performance of the video card (RX480) in games are worse than video card HD7970. Which tested Games: archeage, Lichdom Battlemage, Skyrim reincarnation.

I have EXACTLY the same problem with my "Sapphire nitro+ radeon rx 480 8g GDDR5".
I contacted with Sapphire support and they told me: "Should be AMD driver issue, we'll report to AMD support too. Hope they can fix it on next driver.".
My problem: "I have two monitors connected by HDMI. But if I have my pc a long time turned off, and then I turn it on, the Windows load and it detects the two monitors, but the second monitor show "No signal", however, if I unplug and plug the hdmi (of the second monitor), the image shows correctly." --> If I restart the PC or change resolution on the monitor who has "No signal", the monitors load the image correctly and the "No signal" dissapear.
