HP Envy 17 EW1: External Monitor No Signal Fix
Intel Core i7-1255U • Intel Iris Xe Graphics • Windows 11
The HP Envy 17 EW1 uses the Intel Core i7-1255U with Intel Iris Xe integrated graphics. When an external monitor connected via HDMI or USB-C shows no signal, the issue is usually a display driver problem, an incorrect output selection on the monitor, or a cable that does not support the target resolution.
Press Win + P and Select Extend or Duplicate Check first
Press Win + P on the HP Envy 17 EW1 and select Extend or Duplicate. If the display mode is set to PC screen only, the external monitor receives no signal. This is the most overlooked cause of external monitor no signal issues, especially after connecting a second display for the first time or after a laptop restart.
Select Correct Input on Monitor
On the external monitor, press the input selector button and choose HDMI or DisplayPort depending on which cable you are using. Many monitors default to the last used input and will show No Signal when the active input does not match the connected cable. This applies to both HDMI and USB-C connections.
Update Intel Iris Xe Driver
Visit HP Support, enter the Envy 17 EW1 product number, and download the latest Intel Graphics driver. Install and restart. The Intel Iris Xe driver manages HDMI and USB-C DisplayPort output; an outdated or corrupted driver can prevent the external display from receiving a signal even when the cable is correctly connected.
Test with a Different Cable
Test with a different HDMI cable or a USB-C cable rated for video output. Not all USB-C cables carry DisplayPort video signal — a charging-only USB-C cable will not transmit video. For HDMI, use an HDMI 2.0 cable for 4K output or HDMI 1.4 for 1080p. A damaged or incompatible cable is a common silent failure that produces no signal symptoms.
“My HP Envy 17 EW1 showed no signal on the external monitor. I had forgotten to change Win + P from PC screen only to Extend. A single key press resolved the no signal immediately.”

Why does the HP Envy 17 EW1 external monitor show no signal?
The most common cause is the display mode being set to PC screen only via the Win + P projection shortcut. Press Win + P and select Extend or Duplicate. Also verify the monitor input selector matches the cable type and update the Intel Iris Xe driver from HP Support. Test with a different cable to rule out a faulty or incompatible connection.
What output ports does the HP Envy 17 EW1 have?
The HP Envy 17 EW1 includes an HDMI 2.1 port supporting up to 4K at 120Hz, and a USB-C port with DisplayPort Alt Mode for connecting USB-C or USB-C to DisplayPort monitors. Both ports are driven by the Intel Iris Xe integrated graphics. The USB-C port also supports USB Power Delivery for charging.
Can the HP Envy 17 EW1 run two external monitors simultaneously?
Yes. The HP Envy 17 EW1 can drive two external monitors — one via HDMI and one via USB-C — simultaneously with the built-in display for a three-display configuration. The Intel Iris Xe graphics on the Core i7-1255U supports up to three independent display outputs. Performance at multiple high-resolution displays may require reducing individual refresh rates.
What resolution does the HP Envy 17 EW1 built-in display have?
The HP Envy 17 EW1 includes a 17.3-inch FHD (1920×1080) IPS display with an optional touch configuration. The 17.3-inch display is suitable for productivity tasks requiring more screen real estate. An external 4K monitor connected via HDMI 2.1 can supplement the built-in display for content creation and detail-intensive work.
