graphics card - Why are my video colors getting messed up?


Since around October last year I've been having an on going issue with my HTPC where the color on video will randomly get messed up when watching full screen videos. The display ends up getting heavy pink or green tint to it or the colors appear to be inverted.


For example: Pink saturated image Green saturated image


It seems to happen most frequently when a video transitions between scenes or when entering/exiting full screen playback. It doesn't always happen however. Player software seems to be irrelevant, some seem to be more or less prone to it happening, but none are immune.


Turning the TV off and on again, or switching inputs will get the colors back to normal. Some players seem to detect this though and stop playback with no resume option. I presume for HDPC/DRM reasons. Sometimes after being fixed it will simply glitch again in a few minutes, other times it'll finish the video just fine (and typically glitch after leaving full screen mode).


What I've tried



  • Complete format and re-install of windows 10

  • New HDMI cables

  • New graphics card

  • Tried different HDMI ports

  • Cables are not loose


Setup details




At this point it seems like it is must be a TV problem, but I'm skeptical of that for two reasons. First, the TV's menu system seems to be unaffected. It still displays properly if opened when the problem occurs. Second, I also have a Roku (and previously a cable box) attached to the TV and neither of those have had any issues with their output.


Any ideas as to what is causing this, or what else to check for or try?



Answer



The solution to this problem seems to be to switch to AMD cards rather than Nvidia. I swapped in a AMD R7 250 and have been running it for a few weeks now without a single issue.


Prior to October when the issue started I had also been running an AMD card (HD 6570), which was swapped to a spare Nvidia card after it appeared to have stopped working.

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...
