hdmi - My display is blank when I turn on my HDTV connected to Media Center


When I turn on my TV, it's often the case that the screen is blank and I have to unplug / plug the HDMI cable connected from the Windows Media Center to a Samsung LED TV.


This problem only occurs when the Media Center has played content that contains HDCP data (which is the case if you are using an ATI Digital Cable Tuner or OCUR device).


The card is an ATI HD4550 and the OS is Windows 7.



Answer



Ok, here is a solution that works 100% of the time for me.


1) Buy an HDMI Detective Plus


This gadget basically gets programmed with your TV's EDID and then fakes your Media Center into thinking the TV is on 24/7. Genius


2) Go the software route


Prerequisites



  1. Harmony Remote (Logitech)

  2. HDMIOn.exe


First, you need to ensure that you get the latest Media Center remote configuration file for your Harmony Remote. You can find this device under


Device type: Computer -> Media Center 
PC Manufacturer: Microsoft 
Model: Windows Media Center SE

and includes the ability to send Media Center keyboard commands such as Win+1, ALT+1 etc


Then you need to configure the Activity for your Media Center "Watch TV" action to include an additional remote command, which is to send Media Center a custom keyboard shortcut. Since I am using Windows 7 I selected Win+1 to launch the first item in my taskbar


Now you need to download HDMIOn.exe and place it somewhere on your Hard Drive and then pin in to the TaskBar in the corresponding location that you are using for the shorcut.


Alternativley you can create a shortcut for HDMIOn.exe and assign a shortcut key like ALT+1 to that shortcut.


Now when you press the Watch TV Activity on your Harmony remote, the HDMIOn.exe app will launch causing your HDMI handshake to get resent.

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...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

performance - Single Threaded Qaud Core v.s Hyper-Threading Dual Core

Let's say we have two CPUs, One is Quad Core 3.2 Ghz with 4 Cores, and We have a Dual Core 3.2 Ghz with 2 Cores with 2 threads in each Core (Hyper-Threading). My assumption as a programmer will be, the 4 cores 4 threads should perform faster than 2 cores 4 threads since the second CPU needs to switch between threads in order to emulate 4 cores while the first one doesn't need to perform such switching as each core can perform independently and individually. I want to confirm that my assumption is true, if not please explain why one is better than the other. Answer I do believe thats true - since hyper threading does share some elements - specifically the main execution resources, you'll be able to run 4 full threads at once, rather than waiting for those resources to be freed up. The point of HT is to get better performance with a smaller use of die area - your quad core would generally be a bigger chip - say almost twice as large, than a non HT dual core chip, while a HT...

freeze - How do I stop windows 8.1 from freezing when the screen locks

This happens to me on a regular basis if I leave the computer for upwards of 10 minutes. It didnt do so at first but started after a couple of days. This is possibly related to further windows updates although nothing seems to tie in obviously when looking at my update history. I have to hold the power button in to power off. If the screens have switched off aswell they wont come back on, if they haven't I see the login picture and can move the mouse pointer but nothing happens and no combination of keyboard mashes or mouse clicks lets me see the login prompt. In the event log (type event viewer into the start menu) under system before every Critical problem (me powering down the machine without restarting) I get distributedCOM errors talking about this guid: "The server {BF6C1E47-86EC-4194-9CE5-13C15DCB2001} did not register with DCOM within the required timeout." I also get the same error for this 1B1F472E-3221-4826-97DB-2C2324D389AE. This seems to be a common theme and...
