New owner: XPS 15 9550 and LG 34UM95 help - or other wide/4k external recommendations

Hi there, got a great deal on an XPS 15 9550 which is replacing my Surface Pro 4.

I was using the SP4 to drive a LG Ultrawide 34UM95 3440x1440 via mini display port to the displayport on the monitor.

This LG also has 2 x thunderbolt ports.

Is there anyone here who uses the TB3/USB-C port to drive a thunderbolt monitor and if so, what adapter did you get? (I tried a friends Apple TB3 to TB2 adapter then a TB2 cable to the monitor but this did not work - its become a known fact that this Adapter will not work with mini displayport but it supposed to work with thunderbolt).

I think I could also go usb-c to the displayport on the LG monitor but again could use some recommendations on adapters that actually work.

Appreciate any advice people can offer - even if it is going with a whole new monitor. I just need something bit and high resolution for work.

 

Hi and welcome to the forum.

I've been using the https://www.startech.com/uk/AV/usb-...-over-usb-c-to-displayport-adapter~CDP2DPMM6B on my 9550 with a BenQ BL3201PT to get 4k @ 60Hz for over six months now. It's not a cheap cable but given the legion of problems with TB3 and the 9550 in particular, I went for what I perceived to be a 'quality' solution and have not been disappointed.

The 9550 is a great system but not without it's quirks and needs a little fettling to get the best out of it. Fortunately there's a wealth of relevant information on this forum (thanks to all the regular contributors) so search, read and ask if you can't find what you want.

 

Thanks a lot for the feedback.

I'll look and see if I can get that adapter here in Japan.

I definitely love the potential of the machine and the ability to upgrade it (already went to 32gb of ram and clean install of windows 10)

I was thinking of changing out the SSD since its a Toshiba but ran CrystalDiskMark and was pleasantly surprised at its speeds.

Yes there's definitely lots of great info here. Its a big help.

 

The Apple adapter to TB does not work with Windows machines. I use the StarTech USB-C to TB adapter to drive the LG via TB. The second TB port on the monitor allows me to connect another TB to whatever adapter or TB device. Works perfectly.

 

That sounds awesome. I will check it out thanks!
