Another person PM's me about the same. I told him to switch spectraview off and on again in OSD and then it worked for him. Try the same.
In the info tag, you should see under model SV 2690 after this change (instead of LCD2690WUXi).

This is the problem. I cant access On\off option for Specrtaview. If I press in TagE menu input+ down arrow, nothing happens.
