Is GeForce GTX 980ti required for 4K Ultra HD LED at 3840 x 2160?

HP Phoenix 860-180st
Microsoft Windows 10 (64-bit)

I recently purchased an HP Phoenix 860-180st

- 6th Generation Intel Core i7-6700K
- quad-core processor 4.0GHz
- 16 GB DDR4-2133 DIMM RAM
- 2GB NVIDIA GeForce GTX 960
- Liquid Cooling
- Windows 10 Pro

Soon afterward, my 12-year old HP Pavilion LCD 19” monitor fell into sleep mode and never woke up. I replaced it with a ViewSonic VX2475SMHL-4K 24-Inch 4K Ultra HD LED, Refresh rate 60Hz, Response time 4ms.

After connecting the monitor using HDMI, I could not adjust the screen resolution to 3840x2160. The highest was setting 1920x1080.

I first thought I would need either an HDMI 2.0 or DisplayPort 1.2 cable to achieve 3840x2160. The PC came with a 2GB NVIDIA GeForce GTX 960, but the 980ti was an option I didn’t choose at the time since I had not planned for a 4K monitor. To achieve 4k viewing, I believe I will need the GeForce GTX 980ti.

I will be using the 4K monitor for video streaming, Blu-ray, and Flight Sim software such as FSX, X-Plane v10, or Virtual Pilot 3D. I have a second 24” LCD for general Internet access, email, and MS Office apps. My questions are:

1) Am I correct in that the GeForce GTX 960 will not permit the higher 4K resolution?
2) Which GeForce GTX 980ti brands will function in my HP Phoenix (with a Liquid Cooling System)?
3) Which brand is best (Nvidia, EVGA, Zotac AMP Extreme, MSI)? Overclocking unlikely for now.
4) Are there other alternatives for achieving higher resolutions using the existing NVIDIA GeForce GTX 960?
5) Has the issue with the GeForce GTX 980ti running on Windows 10 been resolved?

Thanks.

Hello,

You ahve purchased model with NVIDIA GeForce 960 (code name Ariia) and this graphics gard based on specification have maximum resolution:
DVI (dual-link) resolution: 2560 x 1600 x 32 bpp @ 60Hz
HDMI resolution: 4096 x 2160 x 24 bpp @ 60 Hz (HDMI 2.0)
Analog VGA resolution (via dongle): 2048 x 1536 x 32 bpp @ 75 Hz
DisplayPort: 3840 x 2160 x 30 bpp @ 60 Hz (DP 1.2)

 

So you should be able to achieve 4K with your current configuration. Make sure you have installed latest driver from hp.com, also check monotor is detected in device manager. Restart the unit only with connected cable between your Viesonic and graphic rad (HDMI 2.0 for example) and then check whether you can achieve 4K resolution.

 

Not sure I need to answer other questions :

2. HP is offering 980i as well, you can contact local HP support for more details

3. There are some differences between these brands, depend on frequency/memory etc. All should work with your unit, not sure whether with liquid cooling, this is specific.
