Can I use a Plugable USB 3.0 to DisplayPort 4K UHD to connect my T540p laptop to my Sampsum 4k UHD monitor?


I just bought a Samsung 4K UHD 28 in monitor. does not want to paly together with my t540p Lenovo laptop. will this usb port help me out??



Thanks for posting. I’d be happy to help!

You don’t mention exactly what problems you are running into, but in looking at the specs of your laptop -->… your unit should have a mini-DisplayPort output. A more straightforward and less expensive solution would be to use one of our mini-DisplayPort to HDMI adapters to connect to your Samsung -->

You could also use our UGA-4KHDMI adapter --> as I do not think your TV has a DisplayPort input (most do not) but it will be more expensive. Keep in mind with both products the refresh rate at 4K will be limited to 30Hz.

Let us know if you have any additional questions.

Thank you,

the monitor is a Samsung 28-Inch Ultra High Definition LED Monitor (U28D590D) with both Display port input and HDMI input

It has a resolution of 3840x2160. my intel display gives out 1920x2160 from my laptop so I get exactly half of a screen. Left half for DP, right half for HDMI. I was hoping these devices might improve my graphics!



It sounds like you have the Samsung Picture Beside Picture (PBP) option turned on. This option is designed to let you have two different inputs appear on the screen simultaneously. In looking at the manual for your unit -->… on page 51 you should be able to verify if that option is tuned on as a possible explanation as to why you are seeing the behavior you are.

If that is the case you should be able to turn the option off and then have the single DisplayPort input fill the entire screen.

Let us know if that information helps and we’ll go from there.




Well Sir, today you are my hero. Perfect remote diagnosis.


You done real good. Saved me a whole lot of grief. Intel had NO freaking idea, Samsung, totally worthless, Lenovo, worse. You sir are good.



Thanks for getting back with the update, and thank you for the kind words they are much appreciated.

Please let us know if you need any help in the future!
