1 year ago It's a flaw between how the card was made and a combination of the Realtek RTD2173 PCON.
You're not getting a true native HDMI port. It's Display Port that is converted to HDMI. This, unfortunately causes issues like that because there are times that I suffer from it on my system hooking it up through my HDTV that is probably far older than your TV.
This is also probably the reason why when connecting anything through HDMI (especially in the case of TVs) that you can't adjust color depth (10-12bit HDMI deep color) or color format (RGB Full or YCbCr 444). I attempted to cover a lot of it in Issue #304
I think a lot of it is that Arc (and it seems to extend to anything Xe based) can't tell what it is connecting to. I saw this in the logs of the Intel Graphics Command Center that when the application requests what the "DisplayInfo" is, it states that it can't find it.
The solution that I found was to use a Active DP to HDMI adapter. It doesn't get rid of the issue completely, but it does reduce it quite a bit. I use a CalDigit version . This has also helped with my issue when the display goes to sleep and loses its "focus" (ie: it no longer recognizes my "SonyTV", changes to "Wired Display", and sets an overscan.
Really, as it stands now, you're out of luck using the HDMI port. Intel making a shortcut using the PCON instead of adding a true Native HDMI port was obviously the wrong decision. If you want a less quirky experience, you're going to have to use the Display Port outputs on the GPU. That requires an adapter.
I don't know if this can be fixed with a firmware update or if Intel realizes their mistake with Alchemist, and this gets addressed in Battlemage,

This is happening with all the TVs i have access to, currently using Philips Tv 32PFS5603 none of them has a DP port, so i'm always using HDMI
steps:
a hard reset of the device (press power to force shutdown) is required to restore video ouput and TV must be on before the pc is powered on
