Hello,

Please may I get some help with a V/S display issue?  With the setup listed below, I am seeing the VRI MCP Combo II (in A/P display mode) not follow the selected V/S if the V/S is negative. P3D, the VRI MCP2 and the PMDG aircraft track V/S together fine (when in V/S mode) if the V/S value is positive. If its negative the VRI display just shows zero. 

LINDA 3.3.5.1363
P3D 5.3.17.28160
PMDG NGXu 737-800 BCF
FSUIPC 6.1.8 
VRI MCP Boeing Combo II version 1.100

Scenario: CMD-A engaged, SPD mode engaged, level flight, then select a lower ALT, press V/S mode, turn V/S knob anti-clockwise. PMDG displayed V/S on the glareshield goes negative as expected, VRI display stays at V/S 0. If/when V/S is engaged and positive, it is displayed on VRI MCP correctly. So in summary, The issue is specifically with selecting negative V/S, which is not displayed on the VRI MCP.

@rpvirtual thank you for the report. I am unable to test the PMDG737 for P3D due to having no licence (out of date). I cannot help at this time.
