display - Philips Brilliance monitor periodically shifts screen by 2 pixels and cuts off screen borders

I noticed a strange issue with my new Philips Brilliance 242B7 (23.8") monitor: more or less every 5 minutes, the image moves 2 pixels vertically or horizontally.

The problem is that when the image moves, the border in that direction is cut off by 2 pixels. Here's some picture (taken obviously with a smartphone, since a screenshot from the OS wouldn't show the issue).

Lower border normal:

Upper border normal:

Left border normal (this is an icon left-aligned on the desktop):

Switching the monitor off and on again solves (temporarily) the problem.

There is no "adjust picture" or similar option in the monitor settings that I could try to use.

The monitor is set to 2560x1440 (native resolution) and is connected to the computer via DisplayPort. The computer has a NVIDIA GeForce GTX 1080 graphic card.

I run Windows 10 Home, and here's is a post from a Mac user having the same issue on a Philip Brilliance 258B6QJEB monitor: http://www.insanelymac.com/forum/topic/315894-weird-issue-with-my-gpu-or-monitor-image-moving-1-px/

What could be the cause and how to fix it?

Answer

Based on nothing more than an educated guess - & not remembering the actual technical term of it initially - this would appear to be a hardware feature of the screen itself...

Pixel Orbiting.

A screen-saver mechanism intended to prevent burn-in on static images.

It's accessed via the OSD according to the manual, page 8 - available from Philips https://www.download.p4c.philips.com/files/2/242b7qpteb_00/242b7qpteb_00_dfu_eng.pdf

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
