VGA_VS and VGA_HS for Tpad

[Altera_Forum]

I had generated niosii core using qsys, this is the component declaration obtained, 

 ======== double_buffer_system u0 (  .clock_0_clock_in_clk (CLOCK_50), // clock_0_clock_in.clk  .clock_0_clock_in_reset_reset_n (KEY[0]), // clock_0_clock_in_reset.reset_n  .vga_controller_external_interface_CLK (LCD_NCLK), // vga_controller_external_interface.CLK  .vga_controller_external_interface_HS (), // .HS  .vga_controller_external_interface_VS (), // .VS  .vga_controller_external_interface_DATA_EN (), // .DATA_EN  .vga_controller_external_interface_R (), // .R  .vga_controller_external_interface_G (), // .G  .vga_controller_external_interface_B (), // .B  .pixel_buffer_external_interface_DQ (), // pixel_buffer_external_interface.DQ  .pixel_buffer_external_interface_ADDR (), // .ADDR  .pixel_buffer_external_interface_LB_N (), // .LB_N  .pixel_buffer_external_interface_UB_N (), // .UB_N  .pixel_buffer_external_interface_CE_N (), // .CE_N  .pixel_buffer_external_interface_OE_N (), // .OE_N  .pixel_buffer_external_interface_WE_N () // .WE_N  ); =========  This is the HSMC I/O i have, ======== module double_buff(   //////////// CLOCK //////////  CLOCK_50,  CLOCK2_50,  CLOCK3_50,   //////////// KEY //////////  KEY,   //////////// I2C for HSMC //////////  I2C_SCLK,  I2C_SDAT,   //////////// SRAM //////////  SRAM_ADDR,  SRAM_CE_N,  SRAM_DQ,  SRAM_LB_N,  SRAM_OE_N,  SRAM_UB_N,  SRAM_WE_N,   //////////// HSMC, HSMC connect to LTC - 8" LCD/Touch/Camera //////////  CAMERA_D,  CAMERA_FVAL,  CAMERA_LVAL,  CAMERA_PIXCLK,  CAMERA_RESET_N,  CAMERA_SCLK,  CAMERA_SDATA,  CAMERA_STROBE,  CAMERA_TRIGGER,  CAMERA_XCLKIN,  LCD_B,  LCD_DEN,  LCD_DIM,  LCD_G,  LCD_NCLK,  LCD_R,  TOUCH_BUSY,  TOUCH_CS_N,  TOUCH_DCLK,  TOUCH_DIN,  TOUCH_DOUT,  TOUCH_PENIRQ_N  );  ==========  I have no idea the VGA_HS and VGA_VS from the core output connected to. Can someone help?

_HS stands for "Horizontal Sync" 

_VS stands for "Vertical Sync"  These signals are used to align the RGB pixels on the screen. (VS will reset to the top of the screen, HS will reset to the left of the screen)

The problem is, there is no vs and hs input for tpad.

The tpad from Terasic only makes use of the data valid signal and does not use H-Sync or V-Sync. If you are lucky, your controller will put out the proper data valid pattern for the display to operate properly. 

 All that said, just let those two outputs be unconnected and hope for the best.
