Static over DisplayPort (WHL #33F5)

Okay, I admit – this is a lazy one. But I’m busy playing Path of Exile :mrgreen:

Before removing the faulty Ednet DisplayPort cable from my desk, I gave it another shot and tried capturing the artefacts on camera. A tad difficult as I noticed that the most prominent stuff is only visible on a pure black (#000) background and is very much gone on colorful backgrounds or even patterned images. Which makes it quite hard to capture without the noise from the now pretty underexposed camera sensor. And the autofocus has nothing to focus on, because if there is, the fault goes away. […]


BenQ EX3501R, AOC U3477PQU and a faulty DisplayPort cable (WHL #33F4)

Well, who would have thought that the BenQ needed another blog post…

Last week, the line flicker described in got significantly worse. I switched graphics cards the week before (Radeon 260X out, 380 in), which resulted in a driver reset and one Windows boot for the short sighted, but it also caused a bit of movement on the cables, as my computer is rack-mounted. Flicker stuff was the same for a few days.

Then it got so bad that it not only had those intermittent lines, but there were entire blocks of lines just black, audio stuttered, and the entire screen went dark for a second every so often. […]


Waveshare 400×300 4.2″ three-color SPI E-Ink / E-Paper display module (WHL #38)

Bit of an upmarket item for today, not the usual Wan Hung Lo…had the honour to make that thing display some demo content for a side project at work. So…why not take some photos, publish the code, and get ahold of a similar unit for use at home?

So this is an e-Paper / e-Ink display, actually a module that consists of the display unit itself and a base PCB that takes the flimsy flat-flex connector, adds some passives and presents a more sturdy interface to the microcontroller that will be handling the thing. Also, the PCB is large enough to offer mount points on each corner. […]


Weißen 128×64 0,96 zoll oled lcd led-display-modul für arduino 0,96″ IIC spi kommunizieren (WHL #6)

…Hi :cool:

I know, it’s been a while. Busy working, busy moving, busy buying metric shittons of furniture that’s not easily available in my size (or budget, or space, or all of them) and takes ages for delivery. Although this city is considered large for German terms, it’s not easy to get what you want – you might as well live in a backwater town. Well, actually I moved to such a lovely place and I couldn’t be more satisfied :)

About the promised “organic” next post: Here it is, I’m back. I’ll also throw in the other headline descriptions, as I actually bought another one for me (which I will review now), and two more for a work colleague who already snitched my first unit. […]
