Geforce GTX 1050TI 4GB not giving UHD on HTPC
I have following specs on my Dell T5500.
CPU: Intel Xeon E5606 2.13Ghz
GPU: Geforce GTX 1050TI 4GB
RAM: 12 gb
PSU: Dell 875W
OS: Windows 10 Pro 64x
Connected to Denon AVR X-2300W (Dolby Atmos 4K enabled AV receiver) via HDMI Premium Cable - from Denon Product Info document: 4K/60 Hz full-rate pass-through, 4:4:4 color resolution, HDR and BT.2020
This AV Receive is then connected to Panasonic LED TV TX-58DX802B (4k UHD HDR display) using HDMI Premium Cable.
My problem is that I can not get 4K from this system. not even 4K @ 30Hz.
I have tried an android TV box to check HDMI Cables they were all giving 4k @ 60Hz directly on TV as well as via AVR.
