How do I know my monitor is not lying? Calibrate a Monitor using the SMPTE Color Bars

Calibrate a Monitor using the SMPTE Color Bars

On professional studio monitors: calibrating your NTSC monitor is done by activating blue channel only.
Some monitors use a grey scale which is what is pictured in this article.
To begin, send the SMPTE color bar pattern to a monitor.
The color bars may be generated in a signal generator or studio camera.
Some non-Linear Editors such as Apple's Final Cut Pro or Adobe Premiere contain bars and tone generators that can be placed on the timeline.
For best results, the monitor should be allowed to warm up before calibration and should not have too much direct light falling on to the screen.
If the monitor has a Degauss button, it should be used to reset the magnetic field on the monitor.
Then, the monitor is set to show only the blue channel of the picture, which on a professional monitor is done by selecting the Blue Only option.
On an older monitor without a Blue Only option, the red and green color channels can be turned off to achieve the same effect.
The resulting picture will appear in different shades of blue or gray.
The aim is to make the color and brightness of the alternating vertical bars match with the smaller rectangular bars underneath them.
The phase and chroma controls on the monitor are adjusted until as close a match as possible is obtained.
Once adjusted, the red and green bars are turned back on.
Brightness (or luminance) is adjusted by the "pluge" pattern of three small grayscale bars which is located beneath the main red bar.
The picture is too bright if all three bars can be distinguished, and too dark if none of the bars can be distinguished.
Ideally, the brightness should be set so that only the right-most bar is visible.
The contrast control should be adjusted so that the 100% white reference square in the lower left is bright enough to appear as white.
If the dark squares on either side appear to glow, the contrast is set too high.

Group Series: Auto Share Content Problem

If you can telnet on port XX into your Polycom Group System then run this command I have attached. You should be able to do that with putty. You can turn the option of auto show content on and off. I have tested this many times myself and this option stays the same even if you reboot the system. If you do a hard reset on the unit will need to turn the option back off.

How to Change the Channel ID on a Polycom Remote

How to Change the Channel ID on a Polycom Remote
ID settings: Default factory is Channel 3

Polycom HDX Remote     |     Polycom Group Remote

Before starting, please note: 

If the remote control is set to Ch. 3, it will control a Polycom system set to anyChannel ID.

• The Polycom Touch Control virtual remote control is always set to channel 3.  If you're using it, it automatically disables the IR remote.  Smart Pairing does NOT have any affect on the IR remote settings.  Using a virtual remote control application like VTC-Remote does not have any affect on the IR remote settings.
• The Power button works on each HDX system within the range of the remote control, regardless of the Channel ID settings.
• If you're using the remote control (and not the web UI) to change the Channel ID, it's easier to set the channel on the endpoint first and then change it on the remote control .
• Unless you're in the process of changing the Channel IDs, the first thing to check when the remote control isn't working are the batteries.  Either recharge or replace them, depending on your type of remote control.



To set the channel on a Polycom HDX remote, use one the the two procedures below:  

On a Polycom HDX, from the remote control using the on screen menus, choose:

System>Admin Settings>General Settings>System Settings>Remote Control/Keypad>Channel ID {0..15, default = 3}

On a Polycom HDX from the web UI, choose: 

Admin Setting>General Settings>System Settings> and scroll down to the Channel ID {0..15, default = 3}

After setting the channel on the endpoint, you must also use the procedure below to set the channel ID on the actual remote control too.  (From Chapter 10 of the Administrator’s Guide for Polycom HDX Systems). 

Note that the channel you select will be displayed in the remote control LCD window. 

 Once complete, test your remote control.

To set the channel on a Polycom Group Series,  the configuration must be done through the web UI.  Browse to the IP address of the Group Series.   Choose 

Admin Settings > General Settings > System Settings > Remote Control, Keypad, and Power> and set the Channel ID {0..15, default = 3}.

After setting the channel on the endpoint, you must also use the procedure below to set the Channel ID on the actual remote control.  (From Chapter 9 of the Administrator’s Guide for the Polycom RealPresence Group Series). 



Once complete, test your remote control.

 

Troubleshooting:  

If your remote control doesn't seem to be responding after changing channels, press and hold the power button for 2 seconds (HDX) or press and hold the hangup button for 10 seconds (Group Series).  These should respond regardless of channels.  If they do respond, then either the remote control or endpoint are misconfigured.  To recover, set the remote control to Channel ID 3. 

 

If connected, a Polycom Touch Control disables the IR control of its endpoint. 

Is there anybody out there?
