DisplayPort 1.2, MacBook Pro 2016, Dell Ultrasharp U2515H, MST
So it looks like my “new” MacBook Pro 2016 with TouchBar and Radeon Pro 460 with 4 MB does not support DisplayPort Multi-Stream Transport (MST). MST allows the daisy chaining of supported monitors.
I got a USB-C to DisplayPort cable from Amazon and connected it to my first Dell UltraSharp U2515H.
The display finally mirrored my MBP, but I had to move USB-C ports seemingly to “wake up” the monitor or MBP. Then I activated the DP1.2 mode on the U2515H since by default DP1.1a is the factory setting.
Then I connnected the video out of the first UltraSharp to the video in of the second UltraSharp. For this, I used the Dell-provided DisplayPort to mini-Display Port cable. I then activated DP1.2 on the mDP port on the second monitor (not sure if I had to do this but thought it made sense).
The second UltraSharp came to life and displayed a mirror of the first UltraSharp. My laptop screen showed one desktop while both UltraSharps displayed a second (mirrored) desktop. The MBP recognized one external monitor, not both.
I also tried using a DP-to-DP cable to interconnect the two DP1.2-compatible monitors together, but that didn’t change the results (yes, I activated DP1.2 for the monitor’s DisplayPort). My MBP is running macOS Sierra 10.12.5.
Now the Dell manual states that only a single external display with resolution of 2560×1440/60Hz is supported by MST, and that’s the native resolution of the Delll UltraSharp U2515H. So there’s that. I tried reducing the resolution of the Ultrasharps seeing if that had any effect, but nope.
So either MST isn’t supported/implemented in the Mac OS X software or Mac hardware or I need to try this again using monitors with lower resolutions. Or most likely, I need to forget MST and go the old fashion route of using two video connections to two monitors.
A Varied Shopping List
- Yonex Voltric 5FX racket
- SanDisk 32GB SD Card
- DisplayPort to DisplayPort cable to daisy chain two MST displays
- USB-C to DisplayPort dongle
Hope this covers it.
Coffee Day 16
All good things must come to an end, and Day 16 marks the end of this memorable, caffeinated voyage to Japan.
My canned coffee drink was sadly dumped at Haneda Airport when we had to go through security for a second time. Having gone through security at Hiroshima, I figured it was safe to buy bottled drinks. But when changing to international travel at Haneda, there was another screening with typical restrictions. So there it went. Instead, I conclude this series with a playful artistic cup of my Starbucks Chocolate Cake Frappuccino with Matcha Shot.
Coffee Day 15
What coffee does a day in Hiroshima bring? A Beans & Roasters Caffe Latte for the Nozomi ride.
Coffee Day 14
Driving from Kyoto to Osaka led to a rest stop where a Wonda Black kept me company.
Again, I didn’t want a drink that could go bad during the day so bitter black it was.
Pieology Kailua Now Open
Don’t exactly know when the new Pieology in Kailua opened for business but have no doubt that they are open. Here’s the photographic evidence.
You can find Pieology Kailua at 151 Hekili St. across the street from Target.
Coffee Day 13
With a new sticker affixed and majority of the labeling in Japanese, I tried this drink and thought the Wonda did live up to its slogan of “Wonderful Coffee.” This drink has the right balance of coffee and sweetness. Enough coffee flavor with some expected bitterness but with just the right amount of sweetness. The appearance is dark so I’m assuming very little to no cream. Probably my top pick overall.
Coffee Day 12
A hot day in Kyoto warranted two drinks in order to keep cool. After walking from the Saga Arashiyama station to the Togetsukyo Bridge, I got an European black coffee via the Georgia brand. Nothing special, but because the day was just beginning, I didn’t want anything with cream that might spoil in the heat of the day.
After more exploring followed by the jaunt back to the train station, I got an energy boost from this Wonda drink that I couldn’t interpret.
Good enough on a sunny day!
Coffee Day 11
Seems like my coffee picks are suiting my tastes more and more. Today’s pick is Suntory Premium Boss “The Mild.” And yes, I guess I like my coffee mild since I like this drink. It’s not too sweet, mildly bitter, but more importantly, it tastes like coffee. I easily finished this drink in no time.
Sometime during the day, I also picked up this sweet Georgia drink.
As the picture indicates, this light brown drink is creamed, and it’s good. But because of the diary, the drink is thicker. Oh, and yes, the bottle is smaller for the typical 140-yen rate.
Coffee Day 10
Today brings Tully’s Coffee Barista’s Latte. For whatever reason, I was thinking of a Starbucks drink full of sugar and cream. Not the case at all. This is espresso and some kind of creamer. Smoother than a straight up black coffee and with a muted bitterness. I just need to adjust my expectation for this drink. I’d get again instead of a coffee.
Coffee Day 9
Today featured a double hit. Sure, I was fatigued by the constant on-the-go. But really, the opportunity and experience of trying a new drink couldn’t go unpassed.
The first drink was more for thirst purposes, but I think I found my favorite canned drink in this maroon can. The Georgia European is slightly sweetened and has cream making this drink easier to drink.
My second hit of the day was opportunistic and commemorative. While waiting for my first Shinkansen ride, there was a Doutor coffee shop in the train station. Handed an English menu since pointing at drinks on display wasn’t working, I got an iced Honey Au Lait which was ready immediately after payment. Very nice! But it kept me awake during the long ride to Kyoto.
