LT1423p wireless model and Windows 10 driver

Now Windows 10 is supported for the wired LT1423p model.

 

What about us wireless model owners? The wireless model plays nicely with Win 8.1 (if you follow Lenovo's instruction and install the latest 5G driver for the USB dongle) and I have get both touch and pen working smoothly in wireless mode at 5G band (well, latency still exists, but very minor)

 

Now that I've upgraded to Windows 10. Lenovo's software does not work on Windows 10. So I can only use the wireless model wired. Lenovo, please add Win10 support for the wireless model. I feel rather bad that now the wired model gets driver update but not the wireless model. At least give us some tips. Thanks.

Re: LT1423p wireless model and Windows 10 driver

I contacted Lenovo for Windows 10 support for the wireless lt1423p, part of Lenovo's business line. They replied Windows 10 is currently unstable (for business use) and users should downgrade to use the lt1423p. Then I asked them to file a request to HQ, hoping enough request will yield action (tech person told me so).

You can do the same like this:
Enter model type lt1423p at this support page:
http://support.lenovo.com/globalproductselector?returnurl=supportphonelist&c=1
Click 'Support Phone List' and then select your country from the dropdown. Call the number, work your way through the phone menu and ask the support person for a solution.

Re: LT1423p wireless model and Windows 10 driver

Hi

 

I don't have this device and it is bad that Lenovo does not have any wireless drivers for Window 10 for it. Maybe it can be usefull for more owner of the wireless version to call Lenovo about it and open a ticket.

 

But just checking on google I noticed it is hard to get information about the Wireless version of this display.

According to what I had read there seems that this device uses "DisplayLink" technology inside for the wireless video.

 

If you have nothing to loose right now, can you give it a try to the newer DisplayLink drivers to see if some of those work. They also list some limitation about Windows 10.  

http://www.displaylink.com/downloads/windows

 

Please notice that I can be complete wrong about this.

 

Just some more questions

1) Can you please post hardwareID of the USB dongle? You can check the hardwareId on Window Device Manager, open the device and on the "Details" tab search for the "HardwareID".

2) I'm just curious about how the USB dongle looks like, I was not able to find any picture of it.

3) Is there any other link when you can download the driver/software that is supposely included (according to the instructions) on the USB dongle?

Re: LT1423p wireless model and Windows 10 driver

This is how the wireless display works -

The displaylink drive is only responsible for compressing video through usb connection and it has nothing to do with the wireless part. The Lenovo software simulates the wireless connection (via the USB wireless dongle) as a USB connection so that Windows sees the wireless connected display as a USB display. That's when the displaylink conversion comes in. The USB dongle is just a plain typical wireless USB dongle like anything sold in the market.

 

Basically you can think of the connection mechanism as using a network drive, only this time Windows sees the drive as a USB drive instead of a network drive due to the simulation of the Lenovo software.

 

Currently because Lenovo choose not to update their software for the wireless model for Windows 10, we are stuck and have to use it wired. Also the outdated Lenovo software will not work with any newer versions of displaylink drive, and the old displaylink drive won't work with Windows 10.

 

For your other questions -

1),2),3) The dongle is like this. But it's rebranded as a Lenovo dongle, you won't find anything about it. It uses a Raylink RT series wireless chip (I can't remember the hardware ID now - in fact I used the ID to find the updated driver). The stock driver that's shipped does not support 5Ghz mode properly.

 

In fact you can actually use the outdated Lenovo software and the updated driver for the USB dongle to force the wireless display to work (also forced installation of the old, Win10 imcompatible displaylink drive), but only 5% of the time. When it works, it disconnects in about a few seconds. The Lenovo software is the bottleneck at this point.

Hi

 

One more thing, does the Lenovo software called something like "Connection Management / LT1423p Control Panel" gives any error when you run it on Windows 10?

Nope. It would simply freeze or couldn't find the monitor.

Re: LT1423p wireless model and Windows 10 driver

Hi

 

I found the Windows 8 driver and installed it on my Windows 10 machine just to look at it. Please notice that I don't have the device (dongle neither monitor).

 

It seems that I understand more about the dongle. It is not only a RA Link wireless adapter, it needs to have more intelligence. According to the files that the driver installed it has:

- RALink wifi drivers

- DiplayLink Graphics Adapter.  (DisplayLink_7.4RC1.exe)

- Something called Marvel Tunnel  (09/13/2013,1.0.0.21)

 

The LT1423p Control Panel Software runs on Windows 10 (64bits) but I'm not sure if it works, since I don't have that device. I guess it can be interesting to know who the DisplayLink Graphics devices (for wireless video and USB) are working on Windows 10 on some other devices.

Re: LT1423p wireless model and Windows 10 driver

Hello from Germany,

any News related to this topic?

I had the same experience after updating to Windows 10 - no possibility to use the wireless connection.

A statement from a lenovo respresentative would be nice.

Re: LT1423p wireless model and Windows 10 driver

Hello All,

I've been able to find out the following information for you; the LT1423 wireless was end of life prior to the Windows 10 release and therefore not included in the support plan.


As users have established,  the display will work with a cable with Windows 10 using the DisplayLink drivers.  To my knowledge there are no plans to support this display with Windows 10. Sorry for being the bearer of news you probably didn't want to read.

Re: LT1423p wireless model and Windows 10 driver

Hi

 

Is there a link when we can see the device model and the EOF date?

 

About the device the only hope is to try to find the hardwareIDs of the dongle and pray that it may work with other drivers from the manufacturers.
