If you're trying to send the data to the monitor digitally, and you're trying to do it with the monitor's DVI port connected to a DVI to VGA adaptor (which is connected to the graphics card) then this won't work since VGA is strictly an analogue interface. The converter will turn the DVI port into an analogue connection.
So, unless your DVI port on the graphics card works, then the TFT LCD monitor cannot receive digital signals.
Alright. With the PC off, hook the monitor up to a DVI port on the graphics card using the DVI cable. Make sure the cable is connected properly, and firmly at both end. Then turn the PC on. If you don't see the POST dialogue on screen or the Windows OS splash loading screen during boot, then check your monitor's onboard display settings and see if there's an option which allows you to switch between analogue (VGA) and digital (DVI) interface.
