U2412M, PC HDMI to DisplayPort cable question

Hi,

I have Lenovo laptop and using U2412M monitor. I do have HDMI to DisplayPort cable. When I try to connect with monitor it tells me that " there is no signal coming from your computer"  Press any key on the keyboard or move the mouse to wake it up. I don't want to use many converters and cables. I want to use single cable and could you please tell me how to move forward with my case?

Many thanks

Hi Chris,

I googled it and found that Lenovo thinkpad X270 has a full size HDMI video out port and a USB Type-C out port.

Lenovo ThinkPad X270 Ports and Inputs

Along the left edge, you'll find the USB-like AC power jack, the cooling exhaust vent, a USB Type-C port (no Thunderbolt 3 support), a full-size HDMI video out, a USB Type-A 3.0 port, and a Smart Card reader on top.

Could you please let me know why HDMI to DVI-D didn't work for me? I restarted laptop and power on as well on the monitor and still didn't work for me.

I have 2 monitors, U2414H and U2417H and trying to connect to HP Elite Book laptop. I have connected U2414H with HP Elite Book Laptop using HDMI to HDMI cable. Its working perfectly fine. But when I switch on U2417H and keep HDMI to HDMI between U2414H and U2417H its not working. Could you please suggest how to connect between these 2 monitors?

Many thanks

Rajendra

Re: U2412M, PC HDMI to DisplayPort cable question

(1) A PC HDMI out port cannot drive two monitors
(2) A PC HDMI out port cannot upconvert to a monitor DP in port. The straight cables are designed to do the opposite =
PC DP out port --> DP to HDMI cable --> Monitor HDMI in port
(3) Two monitors in a DP MST daisy chain cannot be using any HDMI port

 

In a SINGLE monitor setup, this should work =
X270 HDMI out port --> HDMI to DVI cable --> U2412M DVI in port
X270 HDMI out port --> HDMI to HDMI cable --> U2414H HDMI in port
X270 HDMI out port --> HDMI to HDMI cable --> U2417H HDMI in port

 

The only way to run two monitors from this Lenovo ThinkPad X270 is via its USB Type-C out port.


* The power AC adapter must be connected to the Lenovo ThinkPad X270

 

Lenovo ThinkPad X270 USB Type-C out port --> USB Type-C to DP cable --> U2417H DP in port (Menu- Display- MST on)

U2417H DP out port --> U2417H DP to mDP cable --> U2414H mDP in port

Re: U2412M, PC HDMI to DisplayPort cable question

As mentioned above, DisplayPort to HDMI cables only allow a DisplayPort source to work with an HDMI display input, since most (but not all) DisplayPort source ports support switching to HDMI signaling.  They cannot be used in the opposite direction, since HDMI outputs do not support switching to DisplayPort signaling, and displays do not support receiving a native HDMI signal on their DisplayPort inputs.

If you get a USB-C to DisplayPort cable though, you should be fine.
