When you output objects that have arrays in their properties, only 4 array elements are displayed, then an ellipsis truncates the rest:

 
PS C:\> Get-Process | Select-Object -Property Name, Threads -First 6

Name       Threads                    
----       -------                    
acrotray   {3160}                     
AERTSr64   {1952, 1968, 1972, 8188}   
AGSService {1980, 1988, 1992, 2000...}
armsvc     {1920, 1940, 1944, 7896}   
audiodg    {7436, 1460, 2192, 6784}   
ccSvcHst   {2584, 2644, 2656, 2400...}
 

To show more (or all) array elements, use the internal $FormatEnumerationLimit variable. It defaults to 4, but you can change it to the number of elements you want to display, or set it to -1 to show all elements:

 
PS C:\> $FormatEnumerationLimit = 1

PS C:\> Get-Process | Select-Object -Property Name, Threads -First 6

Name       Threads  
----       -------  
acrotray   {3160}   
AERTSr64   {1952...}
AGSService {1980...}
armsvc     {1920...}
audiodg    {7436...}
ccSvcHst   {2584...}



PS C:\> $FormatEnumerationLimit = 2

PS C:\> Get-Process | Select-Object -Property Name, Threads -First 6

Name       Threads        
----       -------        
acrotray   {3160}         
AERTSr64   {1952, 1968...}
AGSService {1980, 1988...}
armsvc     {1920, 1940...}
audiodg    {7436, 2192...}
ccSvcHst   {2584, 2644...}



PS C:\> $FormatEnumerationLimit = -1

PS C:\> Get-Process | Select-Object -Property Name, Threads -First 6

Name       Threads                                                              
----       -------                                                              
acrotray   {3160}                   
AERTSr64   {1952, 1968, 1972, 8188}                      
AGSService {1980, 1988, 1992, 2000, 2024, 7932}  
armsvc     {1920, 1940, 1944, 7896}
audiodg    {7436, 2192, 6784, 4540, 8040} 
ccSvcHst   {2584, 2644, 2656, 2400, 3080, 3120, 3124, 3128, 3132, 3136, 3140,...
 

When you set it to -1, the list is truncated only when the available space is consumed. To still see all values, explicitly use Format-Table and its –Wrap parameter:

 
PS C:\> Get-Process | Select-Object -Property Name, Threads -First 6 | Format-Table -Wrap

Name       Threads                                                              
----       -------                                                              
acrotray   {3160}

audiodg    {7436, 2192, 6784, 4540, 8040}                                       
ccSvcHst   {2584, 2644, 2656, 2400, 3080, 3120, 3124, 3128, 3132, 3136, 3140,   
           3144, 3232, 3240, 3248, 3260, 3268, 3288, 3304, 3344, 3492, 3552,
