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.

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

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...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
