U4025QW, productivity, graphic card requirement?
Hi,
I have got a U4025QW running with Asus RTX 1060 3GB. After some struggle I managed to configure it to run 5120*2160 at 90Hz refresh rate max under DP connection. Knowing that the monitor is capable of 120Hz, the question is what graphic card do i need to push it to 5K2K /120Hz?
Here're some facts,
- In the dell showroom, the same monitor runs fine at 5K2K / 120Hz with an Intel CPU's integrated graphics.
- As far as I know, even the latest NVidia cards like RTX 4090 uses the same display port 1.4a ports as my current dinosaur card. But I would be very disappointed if the problem remains the same should I invest the money.
I hardly game so the context is all about non-3D, productivity applications.
Thank you in advance.

The bandwidth of DisplayPort 1.4 is sufficient for 5120x2160 @ 120 Hz only with Display Stream Compression (DSC), which is not supported by the GeForce 10 series cards.

@litharge Thank you! Is there a place where I can refer to NVidia GPU's support status of DSC?

It should be supported by any modern card. GeForce 10 was the last generation that didn't.
This monitor also has HDMI 2.1 which can drive the full resolution at 120 Hz.
(FWIW, I use this monitor with an AMD Ryzen APU.)

No, I run 5120x2160@120Hz over DisplayPort (with DSC).
I have the Ryzen PRO 5750G in a ROG Strix B450-F Gaming II motherboard. I don't think my hardware supports HDMI 2.1, and I use Linux where AMD's drivers don't support HDMI 2.1 anyway.

@litharge thanks again! I'll go get a 4060 / 4070 then.
