Okay, weird issue. My RX 580 outputs HDMI video to my TV just fine, but not to my KA242Y monitor.
I've tested every individual component and all of them seem to work just fine. Here was my test procedure:
TEST 1:
PC #1 w/ RX 580 > HDMI cable #1 > KA242Y monitor: Doesn't work. All fans spin up, but black screen on boot.
TEST 2: Removed RX 580, connected motherboard to monitor.
PC #1 w/o RX 580 > VGA cable > KA242Y monitor: Works. Boots to BIOS.
Test 3: Reinserted RX 580, connected video card to monitor, disconnected motherboard from monitor.
PC #1 w/ RX 580 > HDMI cable #1 > KA242Y monitor: Doesn't work. All fans spin up, but black screen on boot.
TEST 3: Plugged TV into PC using longer HDMI cable.
PC #1 w/ RX 580 > HDMI cable #2 > TV: Works. Boots to BIOS.
TEST 4: Plugged other PC into monitor.
PC #2 w/ RX 6650 XT > HDMI cable #1 > KA242Y monitor: Works. Boots to BIOS.
TEST 5: Plugged first PC into monitor.
PC #1 w/ RX 580 > HDMI cable #1 > KA242Y monitor: Doesn't work. All fans spin up, but black screen on boot.
I think I've isolated the issue to an interaction between the RX 580, HDMI cable, and monitor, but I have no idea what that could be. Any ideas?
