I am a user who loves AMD RADEON VGA CARD living in Korea.
I can not speak English because I am Korean.
So we are getting help from the Google translation program.
Please understand if English is strange ㅠ - ㅠ
I am currently using the RX480 and two RX VEGA64s I bought today.
And I am using old TV CARD called ONAIR GT (https://www.amazon.com/OnAir-GT-Mobile-Receiver-HDTV-GT/dp/B000GGQ55M/ref=pd_rhf_se_p_img_1?_encoding=UTF8&psc=1&refRID=FEC7Z4DPQ1R8M0S2KKFB).
I used the ONAIR GT TV CARD from Crimson Driver 16.10.1 ~ 17.4.1 for RX480 without any problems.
However, since Crimson Edition 17.4.2 Optional, you can not use TV CARD as a serious bug.
If you turn off the monitor while watching ONAIR GT after 17.4.2,
The video and audio of TV CARD are blocked and an error is generated and forced termination.
This is a symptom that has never been seen before "16.10.1 ~ 17.4.1".
Has anything changed since 17.4.2?
Problems occur between 17.4.2 ~ 17.7.2 ㅠ - ㅠ
So I bought a new RX VEGA64 today.
But oh my god .. RX VEGA64 has the same bug.
RX VEGA64 driver is win10-64bit-radeon-rx-vega-software-17.30.1051-b6-aug7.exe
If you install the VEGA 64 driver, turn on the TV CARD, and then turn off the monitor, the audio and video of the TV CARD will be cut off and forcibly terminated.
Stand by signal seems to be abnormal.
I want a quick fix.
16.10.1 ~ 17.4.1 ONAIR GT normally.
At 17.4.2 ~ 17.7.2 I can not turn off the monitor.
AMD engineers, please solve it. I waited months, but the symptoms did not go away.
