HP ProBook 450 G5 external display resolution and refresh rate

[max56728]

Hi all,

my goal is create a dock station with my HP ProBook 450 G5. I would like to achive this goal without using any dock station. The laptop has on board the GPU Nvidia GeForce 930MX and has two ports to connect an external display: 1 HDMI and 1 DispalyPort.

I contacted HP Support to ask which are the resolutions and refresh rate available. HP Support told me that the max HDMI resolution is 1920x1080 and that my laptop has not a display port. I checked on the User Manual and is writtent it has. To be sure, I made a photo of the USB-C port on my laptop and once enlarged I can clearly see the D symbol with a dot to indicate it is a DisplayPort.

I cannot believe that the max resolution of Nvidia GeForce 930 MX is 1920x1080. Should be at least 2K @60Mhz or even 4K. I contacted Nvidia and they refuse to answer as they tell me that they sell the chip to HP and then HP do what they want.

QUESTIONS:

1. What are the resolution and refresh rate available?

2. Have anyone of you connected an external monitor via HDMI? Max resolution and refresh rate?

3. Have anyone of you connected an external monitor via Displat Port? Max resolution and refresh rate?

Many thanks to all.

Best regards.

From its manual

VGA (Dsub 15-pin) supporting:

● 2048×1536 external resolution at 60-GHz

● Hot plug/unplug and auto detect

● HDMI 1.4b

Answers:

1.  2048×1536 external resolution at 60-GHz
2.  For HDMI, max 1920 x 1080 @ 60Hz - nearly all HP machines with 1.2 or 1.4b have this resolution for external monitors,
3. For Display Port. I have not tried direct, I'm using DP to HDMI and get 1920 x 1080. I've got 5 monitors mow, don't want to spend more money. Wait for when one fails.

Regards.
