Can a hp 17"-cp0700dx laptop support two display monitors?

[Pete_H1]

I am trying to connect two display monitors to my hp 17"-cp0700dx lap top.  When I go into display settings/multiple displays and select "Detect other display", it comes back and says "We didn't detect another display".  I have one display plugged directly into the laptop via the hdmi port.  I have tried plugging the second display into a multiport adapter with a 2nd hdmi port.  I have also bought a 2nd adapter and tried plugging the second display in using a display port, but nothing works.  Any help would be greatly appreciated.

There is only one video port, #2

The USB ports on this laptop cannot transfer video.

I assume you want all 3 displays to be different.

You can attach one monitor to #3 HDMI easily

You can add an additional display by either projecting over WiFi or using a USB adapter.

You can project your laptop to any WiFi enabled system such as TV or Monitor with WiFi adapter
Some TV are smart but others need a dongle such as ROKU or Microsoft.

If you get a USB adapter be sure to read the reviews. Do not get an adapter that mentions thunderbolt as that means your laptop needs to have a thunderbolt port.  Your USB-C port is NOT thunderbolt.

Note that WiFi will lag. A USB2/3 adapter will also lag but not as bad as WiFi.

Thank you for the information.  And yes, I do want all 3 displays to be different.  I had used a USB-C multiport adapter (with two USB ports, a hdmi port, a USB-C port, a CATV port, and a hdmi port), and plugged into the hdmi port, but it did mention thunderbolt.  I also tried using a USB-C port to display port adapter, plugged into a display port to hdmi adapter, and then plugged into the additional display, but that did not work either.  How would I connect a USB2/3 adapter?

It just plugs into the USB2 or USB3 port and has HDMI

Anyone of the ones l gave the amazon link to.  Just make sure it is USB2 or 3 and not C or thunderbird

check reviews also.

There is a limit on how many displays you can have and it is a function of refresh, resolution, color depth and bandwidth

There needs to be enough video memory to hold icons for 3 screen.  That can be a problem for laptops as the video memory is small or shared with the cpu.

Lag is only a problem for games

If you have a smart TV or roku then enter the windows key plus "p" and the tv or roku will show up and you can project to it.

This link here gives instructions on adding a laptop to desktop as a monitor or vice-versa using Wi-Fi
Android can also do this as shown here
Once you are projecting on the screen you can select "mirror" or "extend"

This will either duplicate the screen or give you a second display.
Note that WiFi will lag. A USB2/3 adapter will also lag but not as bad as WiFi.
You would not want to project a game to a larger monitor using WiFi but it would work nicely for web browsing, Office apps or anything other than a first-person-shooter game.

If you get a USB adapter be sure to read the reviews. Do not get an adapter that mentions thunderbolt as that means your laptop needs to have a thunderbolt port.

Even playing solitaire on laptop the wifi lag to a tv is unbelieve slow yet a movie or podcat works fine.

Hi.

I just posted a similar question for what I suspect is a very similar model (17-cn2070cl) laptop.

Were you successful in connecting two external monitors to your laptop and do you now have 3 working monitors including the one on the laptop?  If so, what solution did you use?

Thanks in advance!
