Purchase of 4K Display (Dell P2715Q)

I bought Dell 4K Display P2715Q. I’m using with New Macbook (12 inch) and Vaio Z Canvas.

DELL P2715Q

It is difficult to set up. Many problems had happen. It might be because of large bandwidth usage.

Screen flickering with Included cable

This problem had happened when connected with Vaio Z Canvas. The cable connecting was the cable which converts mini DisplayPort into DisplayPort.
Sometimes screen flickering happend, sometimes it became blank screen. Sometimes becomes stable. They happened in any resolution mode.

I noticed that it became stable when putting up the cable little bit. I think connectors or cable around connecter had broken, so I purchased new cable. I bought Cable Matter’s mini DP to mini DP cable from Amazon.
My display became very stable when using this cable. This flickering problem was caused my the included cable.

Some people said the included cable was wrong at some review sites (Reviews for P2715Q at Yodobashi Camera, thread of this display at 2ch and so on.)

Unstable when 4K

This problem was also happend when using with Vaio Z. Sometimes I could not select 4K resolution mode. Or sometimes become unstable when select 4K.

This problem caused by combination of Vaio Z Canvas and Windows 10. I updated my BIOS Firmware at Vaio’s site (BIOS R1090VE Windows 8.1/Windows 10アップグレード用) then this problem had dissapeared.

Few flickering when using with New Macbook 12 and HDMI 4K30p

This problem was rarely happened. This combination was almost stable. But sometimes white screen flickering happened repeatedly (about 30 seconds period).
This was because of 7m long HDMI cable which I used. I had shorter (2m) cable, so I switched cable to it, then this problem had dissapeared.

I bought 4K monitor, but no machine can play 4K60p contents

I cannot see any 4K60p contents smoothly.
I had not any PC’s which could play 4K60p movies. My Vaio Z Canvas could not too. Dissapointed.

No problem with Linux

I’m using this display with Linux on Vaio Z Canvas, no problem happens after installing BIOS update firmware. I could use as 4K 60Hz with Gnome3 normally.

Misc.

I had used 2K Dell monitor. New 4K display is lighter than my old display. My display arm became able to move up and keep. Light thing is good.

Also USB 3.0 Hub functionality is a little bit useful. Good.

Vientiane: Central Bus Station has been Moved (2015/10/14)

BUS-EC

Central Bus Station (CBS) in Vientiane had been moved. CBS has many buses which goes to north Thailand and many places in Laos.
Maybe this is a temporary moving because of construction of new bus station building. New temporary bus station is located about few hundreds meters from original place. So it could go by walk.

List of destinations

There was a sign like this:

Information sign about Bus station (Maybe)

I cannot read Lao language (Tell me if this is wrong understanding) but maybe this is like this:

Under construction

CBS is under construction. Bus station divided two places. Please go there.

CBS1 (North) has buses depart for:

  1. Laos – Thai International Bus
  2. Bus 29: Dongdok
  3. Bus 23: Thangon
  4. Bus 20: Dongkhamxang)
  5. Bus 32: Donepamai

CBS2 (South) has buses depart for:

  1. Bus 14: Friend ship bridge (* and also goes Buddha Parl)
  2. Bus 08: North Bus Terminal
  3. Bus 30: Thongpong – Tadthong
  4. Bus 32: Phontong
  5. Bus 33: Nongtha
  6. Bus 49 Nongteang)
  7. Bus 05 Namxouang)
  8. Bus 06 Pialard
  9. Bus 19 Paksap

North Stop (CBS1?)

Buses for Thailand etc. departs from here.

This is a little bit south from original position. Not far from.

This is a photo of CBS1. It becames a litlle bit messy, and tight place.

CBS North (CBS1?)

CBS North (CBS1?)

South Stop (CBS2?)

Buses for Friend Ship Bridge (Border gate place for Thailand), Buddha park etc. departs from here.

This is a little bit fat from original position. It is a road side bus stop rather than “Bus Station”.

So be careful if you will go Vientiane now.
