A video apparatus has a first connector (28) for outputting first RGB signals (R42, G42, B42), a second connector (38) for receiving second RGB signals (R2, G2, B2), and an On-Screen Display circuit (26) generating third RGB signals (ROSD, GOSD, BOSD). A RGB generator (46) generates fourth RGB signals (R46, G46, B46). A first RGB switch (40) is connected to the second connector (38) and to the On-Screen Display circuit (26) for receiving respectively said second RGB signals (R2, G2, B2) and said third RGB signals (ROSD, GOSD, BOSD). The first RGB switch (40) outputs fifth RGB signals (R40, G40, B40). A second RGB switch (42) is connected to the first RGB switch (40) and to the RGB generator (46) for receiving respectively said fifth RGB signals (R40, G40, B40) and said fourth RGB signals (R46, G46, B46). The second RGB switch (42) outputs the first RGB signals (R42, G42, B42). A process to control such a video apparatus is also proposed. <IMAGE>
