I recently purchased an LG UltraWide 21:9 display. Why an ultra-wide and not 4K? a) I write code for a living and this is a great way to get two windows full size side-by-side without an extra monitor. b) It was only $130 instead of $400 due to a Best Buy sale. Sold!

I get home, connect it to my Surface Book, and nothing works. The screen just blinks on and off, on and off, blinkety blink, blinkety blink. No Bueno. Changing the cable made the blinkety blink go away, but the display control panel would suggest trying different settings, and wouldn’t light things up.

My friend Shane recommended I get an Active MiniDP to HDMI adapter. So I bought one on Amazon. Still, I didn’t want to wait… that’s 2 days with Prime shipping, and not fast enough.

So, I looked into the MiniDP adapter I was using. I found out it only supports up to 1080P! Maybe it’s DP 1.1 or something. Whatever it is, it couldn’t support a 2560×1440 or thereabouts display.

Fry’s had the answer – I made sure I found a MiniDP to HDMI adapter that clearly stated it supports 4K and MiniDP 1.2. The particular product I purchased was the Cirago Mini DisplayPort to HDMI Display Adapter.

I got home and the adapter worked flawlessly.

I hope that helps anyone having a similar issue!
