Connected 4K TV to Vega 56, lots of problems
Hi guys. I'm sorry but this is going to be kinda long.
First off, I just bought a 4K TV for the first time and I have a 20 ft HDMI cable running under my carpet from my PC to my TV. My Vega 56 has 3 DP and 1 HDMI. My HDMI is connected to my 2nd monitor (Display 3 according to Windows) for work. My main monitor (display 1) is connected via DP and my TV (display 2) is connected via DP but it has a HDMI to DP adapter since connecting it to the HDMI port wouldn't let it display in 4K, but doing it with the DP adapter will.
My problem has to do with Windows's display. I have my desktop extended between display 1 and 3 so I can do my work on it no problem. Now here is where the problem comes in. Windows wants to automatically extend the display to display 2. I don't want that. I want Display 2 to only come on when I select it as "Display only on Display 2" but that option isn't available.
Also, when I click HDR and WCG, to go on, the slider clicks on and it asks me to keep or revert back and I click keep but then it reverts back right away.
Last but not least, Windows considers my 1440p Asus monitor as Display 1 but Radeon considers it display 2. Could that be a problem? If not then I'm not going to worry about it.
I have some screenshots here if they help. Thanks anyone who can help with this.
PS: When I tried to connect the TV it worked well and I had to duplicate the displays, then I had to click "display only on 2" and then I could game on it. Then I clicked to throw the display back to my monitor and my 2nd monitor and now Windows keeps showing Display 2 coming online, then offline, then online, and it's freezing up my computer. Ugh!
My TV (2) model number is RU7300
My main (1) monitor is MX27AQ
My old (3) monitor is a 2009 HP It's connected via a DVI to HDMI cable because it's 10 years old and it doesn't have HDMI.
