This software requires no expertise in terms of monitors and LCD-s, nor any expertise in the field of screen technology.

It is a fairly simple and small test program that can be of great benefit to all PC users. IsMyLcdOK is primarily designed to quickly become the main feature of the program and that is the search for dead or paralyzed pixels. # Pixel Tester with different colors and gradient:

Testing for dead pixels is very simple ) from the Category Test Tools for Windows IsMyLcdOK does not have to be installed and can be executed easily from the desktop,Īnd can be carried on a small usb-stick or other memory device. Many manufacturer's provide the highest industry standard dead pixel policy. Leung says he will be "contacting Surjtech directly," presumably with the hope of getting a new Pixel laptop so that he can continue his USB Type-C cable reviews.IsMyLcdOK is a small program but effective solution to easily check for dead/paralysed/stuck pixels on LCD monitors. If only Surjtech had put as much thought into the actual electronics as the moulded strain relief.
Well-made with High Quality: Best quality cable in the market - aluminium alloy connector & high density braided nylon net for long-term use The combination of sturdy construction with a flexible jacket and USB 3.1 Type C connector with molded strain relief provides a cable with reliable performance and long life.

Considering the three other compounding issues, though, it sounds like Surjtech just doesn't know how to make a USB cable.Īnd finally, for a few more laughs, I dug up the original Surjtech cable product page from the Google cache. If the miswiring was the only issue with the cable then Surjtech could plausibly defend this as a one-off manufacturing fault. It is NOT actually a USB 3.1 cable, even though it has a blue connector on the A side and SuperSpeed logos. The Vbus pin on the Type-A plug is tied to GND on the Type-C plug."Īnd that's not all! Later, after posting about his woes on Google+, Leung found a battery of further issues:Ģ) 10 kΩ resistor instead of 56 kΩ resistor used.ģ) resistor hooked up as a Pull-down instead of a pull-upĤ) Wire is COMPLETELY missing SuperSpeed wires.
The GND pin on the Type-A plug is tied to the Vbus pins on the Type-C plug. What he found was really quite shocking: "it appears that they completely miswired the cable. To find out what sort of devilry had fried his gear, Leung then analysed the cable with a breakout board and a multimeter. (As far as Verified Boot is concerned, the controller might've been compromised in some way.) Advertisement Unfortunately this meant that the laptop could no longer boot up: because Chrome OS's Verified Boot tech could no longer verify the embedded controller, it would only boot into recovery mode. Upon further analysis, Leung found that the cable had killed the Chromebook's embedded controller, a chip that manages tasks such as keyboard initialisation, USB charging, and reading temperature sensors. Not only did the cable kill the analyser, though, but it also fried both USB Type-C ports on Leung's Chromebook Pixel: "Neither would charge or act as a host when I plugged in a USB device such as an ethernet adapter." I tried resetting the Twinkie analyzer and having the firmware reflashed, but it continues to exhibit this failure," Leung wrote. Basically, as soon as the cable was plugged in and turned on, it completely fried the Vbus line on the Twinkie USB PD analyser.
When testing a Surjtech 3M USB A-to-C cable, the cable was so bad that it fried his Chromebook Pixel laptop and two USB PD (power delivery) analysers.Īt the time of publishing, it looks like the Surjtech cable has already been removed from Amazon, but Leung's review lives on. Benson Leung, the Google engineer who moonlights as a tester of dodgy USB Type-C cables, has sadly performed his last act of tech vigilantism-at least for now.
