Second monitor shows no signal after switching graphics card until I power on the TV!
My System: Intel Core i9-10900K MSI MPG Z490 Gaming Edge Wifi Corsair Vengeance LPX 32GB (2x16GB) DDR4 3000MHz ASUS TUF Gaming GeForce RTX 4070 12GB GDDR6X OC Edition (before it was the MSI RTX 2070 Gaming Z 8G)
Hey, I recently upgraded from my MSI RTX 2070 Gaming Z 8G to the ASUS TUF Gaming GeForce RTX 4070 12GB GDDR6X OC Edition. I have two Monitors connected to it via Displayport (ASUS TUF Gaming VG27AQ & iiyama G-MASTER G2730HSU-B1) and a TV via HDMI (LG OLED C2). Before everything was working fine, but after installing the new card, one of the monitors says it has no signal. The weird thing is that it gets a signal and wakes from sleep the second I turn on the TV. After that I can turn the TV off again and the monitor stays on. This problem occurs after every cold boot (so after the pc was turned off for a while) but not after a restart or short boot. I changed some cables and found out, that whatever monitor is connected to the primary displayport (the one left of the hmdi port) is the one that gets a signal after a cold boot and the one connected to either of the other two displayports gets no signal until I turn on the TV. I thought I may got a card with faulty porty, but after sending it back and receiving a completely new ASUS TUF 4070, this problem persists. So it has to be another thing about my system. I also bought new Displayport 1.4 and HDMI 2.1 cables and this didn't fix it. I don't have the problem when I put my old 2070 back in. So could it be a compatibility-issue with my other hardware? Mainboard, CPU, anything? I feel like I'm going insane... thanks in advance My System: Intel Core i9-10900K MSI MPG Z490 Gaming Edge Wifi Corsair Vengeance LPX 32GB (2x16GB) DDR4 3000MHz ASUS TUF Gaming GeForce RTX 4070 12GB GDDR6X OC Edition (before it was the MSI RTX 2070 Gaming Z 8G)
does this occur when your TV is not connected? Review the card instructions carefully. On my system I can switch between primary DP and decide whether to use HDMI or DP/USB. I cannot switch to another DP if I'm using HDMI. This was a note included with the GPU and isn't mentioned elsewhere. Also, the plugs on the ports are colored differently for clarity.

Also verify Windows project settings by pressing win+P. Every project record retains the Nvidia control panel configuration for multiple displays.

I cannot switch to another DP when using HDMI. This was a note included with the GPU and isn't mentioned elsewhere. Also, the connectors on the ports are colored differently for clarity.
