I've recently upgraded my setup from 1440p to a couple of 2160p (180hz) monitors, while also keeping a 1440p TV mounted above them. Originally, everything was working fine when I just had my 1440p (240hz) monitors, but now it seems like I can only have two of the three displays active at the same time. I suspect that my graphics card is limited in how much bandwidth it can manage. As a workaround, I connected the TV to my motherboard, but when my computer goes into sleep mode and wakes up, I face similar issues where only two monitors wake up, or it keeps flickering as if it's trying to recognize the third monitor like a fresh connection. The only fix I've found is to unplug and re-plug one of the monitors. I'm hoping for any advice on how to solve this without needing to buy another graphics card. My specs are as follows: GPU: 4070 Ti Super, Motherboard: MSI B760 Gaming Plus WiFi, CPU: i9 - 14900k.

Have you tried lowering the refresh rate on the two displays to 60hz? Keeping your main monitor at the higher setting might help stabilize things.
It sounds like a bandwidth issue since the TV is connected via HDMI and the monitors via DP cables. Double-check all settings on the TV and see if you can adjust anything there. Sometimes, those settings can affect how it all connects, especially after waking from sleep.
The TV is only 60hz. I think if I lower the refresh rate on my monitors, it might force me to drop the resolution to 1080p as well. I’ll check the specs on my monitors too; they’re Samsung 27" Odyssey G70F, and I believe they can hit up to 360hz at 1080p.
