try cvt:

$ cvt 1400 1050 60
# 1400x1050 59.98 Hz (CVT 1.47M3) hsync: 65.32 kHz; pclk: 121.75 MHz
Modeline "1400x1050_60.00"  121.75  1400 1488 1632 1864  1050 1053
1057 1089 -hsync +vsync

$ cvt 1400 1050 75
# 1400x1050 74.87 Hz (CVT 1.47M3) hsync: 82.28 kHz; pclk: 156.00 MHz
Modeline "1400x1050_75.00"  156.00  1400 1504 1648 1896  1050 1053
1057 1099 -hsync +vsync
