Laptop Envy x360 m convertible. Use of UHD external monitor

[Carluzino]

I have 2 external monitors working at 1920 x 1080.  I would like to change at least one of them for a UHD monitor to work at 3840 x 2160.  Will the laptop video be able to handle? and if it will, should it be on USB-C or HDMI connection?  Will it work with 2 UHD monitors?  Thanks in advance.   Carlos

@Carluzino, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Your HP ENVY x360 - 15m-dr0012dx can support at least one external 4K (UHD) monitor at 3840 x 2160, but there are a few key considerations regarding connection type, refresh rate, and multi-monitor support.

🔍 Laptop Graphics Capabilities:

The HP ENVY x360 - 15m-dr0012dx typically comes with:

• Intel UHD 620 Graphics integrated into the 8th Gen Intel Core i7-8565U processor.
• Sometimes accompanied by NVIDIA GeForce MX250 (in optional configurations).

Intel UHD 620 supports:

• Up to 3 displays simultaneously (internal + 2 external).
• 4K @ 60Hz via DisplayPort (DP), and 4K @ 30Hz via HDMI 1.4.

So the determining factor is the ports on your laptop:

🔌 Port Analysis:

✅ HDMI Port (most likely HDMI 1.4b):

• Supports 4K @ 30Hz only.
• Suitable for UHD office or productivity use, but not ideal for video editing or gaming due to the lower refresh rate.

✅ USB-C Port:

• This laptop does have a USB-C 3.1 Gen 1 port, but it does not support video output via DisplayPort Alt Mode—meaning it can’t natively drive a monitor via USB-C.

🔹 You can’t use USB-C → DisplayPort/HDMI adapters with this specific model for external displays.

🖥️ Summary of What You Can Do:

1 x 1080p + 1 x 4K (30Hz)✅Use HDMI for the 4K monitor
2 x 4K monitors (simultaneously)🚫Laptop doesn’t support 2 x 4K due to GPU and port limitations
4K monitor at 60Hz🚫 (natively)Only possible via DisplayPort (which this laptop lacks)
USB-C video out🚫USB-C doesn’t support DisplayPort Alt Mode on this model

✅ Recommendation:

• You can replace one 1080p monitor with a 4K monitor, but you’ll be limited to 30Hz over HDMI.
• For general productivity, reading, spreadsheets, or static content, 4K @ 30Hz is usable.
• If you need 60Hz, you would need a DisplayLink-based USB docking station that uses USB 3.1 for display output.

💡 Optional Workaround for Dual 4K:

• Use a DisplayLink USB dock (like the Plugable UD-6950Z or similar):
  • Supports dual 4K @ 60Hz via USB-A or USB-C.
  • Uses driver-based rendering, not GPU-limited.

I hope this helps. 

Take care and have a good day.
