Same here j4205 on samsung 4k. Only solution for me to get video output is to put the hdmi cable in a different display wait for image and then put the hdmi cable back in the tv. This works for a while then again no video.
Vincenth' s workaround also works for me. Boot whitout cable connected and after windows started connect the cable. Bios is 1.20 tv is UE55K6000 on latest software. Also tried to change some tv settings trough the service menu. INFO - SETTINGS - MUTE - POWER On buttons. Edited by W1ll8m - 15 Jan 2017 at 2:30am |

Hi all
I have the same problem with the same motherboard J4205 with my TV Samsung too. I also tried with an adapter HDMI->DVI to connect to a monitor through DVI and I have no signal on monitor too. So seems that HDMI is not working for me. I followed your walkthrough and it doesn't work for me :( I asked to AsRock for support and waiting for an answer hoping they can solve my problem. I'm thinking about sending back it to my seller and change with another board. |

Hi Vincent
I had a similar problem with my J3455 which is quite similar product. In my case I could get the picture only if I connected the hdmi port to the amplifier and then made the quick switch. See this http://forum.asrock.com/forum_posts.asp?TID=4099&title=j3455itx-hdmi-edid-with-4k-display I am having also some mysterious problems with usb ports cutting in and out so I have contacted my seller for replaicement/repair. Maybe Asrock have a bad patch of motherboards. Edited by hjhamala - 31 Dec 2016 at 6:46pm |

[URL=][/URL]I recently bought a J4205 ITX that I use connected to a 4K samsung TV with the HDMI output.?
In order to make it work I have to : 1- disconnect the HDMI cable from the motherboard 2- boot the computer - I wait enough to be sure that that windows 10 is at the login screen 3- start the TV 4- connect the HDMI cable. Then everything works perfectly. However, if I restart the computer, then no more HDMI signal. The same occur if the TV is stopped for too long. The only work around is to shutdown the computer (I hold the power button 3 to 5 sec), disconnect the cable and proceed as explain above. I took the decision to return the card bought on amazon and hope that it is just a problem with this card. But, I have actually some doubt as everything works wonderful when the HDMI is well detected. By the way, I tried with 2 different HDMI cable? In the meantime I put back my old ASUS A3-ionT deluxe that doesn't this issue. If you have any idea how to fix this ? Is it a well known issue ? Is a fix in preparation ? Should I consider another card to get the 4K decoding ? Thank you for your feedback. Vincent Edited by ASRock_TSD - 06 Jan 2020 at 5:09pm |
