E02 - black screen

Hello,

I build one Windows Multipoint 2012, I have 5 TS licences for Multipoint server
Also, I download the drivers from Microsoft site, Install them and after that I was able to see my Wyse E02 on the console.
The only thing is, I can’t see any on the screen… My keyboard cap/num lock light are ON. Did I miss something on the configuration? I’m using an old Dell 19”, when I start the E02, my light goes from orage to green and stay green so I know my screen receive something from the client. I was looking for a dell/wyse post screen or something showing the device is started..

Any help/suggestion appreciate.
