AW3225QF, three, not working on GeForce RTX 4070 Ti Super
Hi
I have a problem with a triple Monitor setup ( 3 x Alienware AW3225QF) with a 4070 Ti Super. No matter what I try with the configuration in Windows Setup or the Nvidia Software, only 2 of the three Monitors are active at the same time.
Any suggestions how to solve the problem?

4K, 240 Hz requires DSC in order to provide enough bandwidth over DP 1.4.
With 3 monitors you will not have enough internal heads available to drive 3 monitors simultaneously as you will typically only have 4 internal heads and each monitor will require 2 heads.
Not even an RTX 4090 can drive triple displays with DSC enabled at those refresh rates.

The RTX 4070 Ti Super can support maximum resolution of 4K at 240Hz or 8K at 60Hz with DSC. You take that maximum bandwidth and calculate the combination of monitors sharing among them for a supported setup.
For example:
1 x 8k60hz monitor
1 x 4k240hz monitor
2 x 4k120hz monitors
4 x 4k60hz monitors

uff.. thank you for the answers.. looks like that was a bad and expensive choice for a triple Monitor setup.
btw 2 x 4K240Hz are working with the 4070 Ti Super.

I tried to setup the Monitors to Console Mode, but as soon as I use the DP Kabel.. well, it's not working for me.

Until DP 2.1 becomes more wide spread, there will be these issues of running out of bandwidth with these high refresh rate monitors.
