Yes, is possible now setting the contrast and the all display features with the PCIExpress VGA card, BUT: need to connect one small OSD PCB controller.
the OSD PCB controller is the same as the standard TFT display, where give the key: SETUP, Auto ADJ, +, -, Enter.
On the Groove Keyboards on rear side we have included ONE small witch for make the Auto Adjust TFT, BUT on MS cases ( developed many years ago) do not give one hole available for insert this AUTO Adjust switch.
Also on new Groove is not developed for support the 5 switch setting, just one in replace of the VGA out connector of the PCIExpress Card.
On request, I can shipping the OSD controller BUT then you have to open the TOP of the MS for make the setting.
After saved the new settin remain on Eeprom status.
Before we shipping the PCIVga, we just run it and auto adjust for the first setting, this is enough.
