said tower having a tower width, a tower depth and a tower height; said housing having a housing width, a housing depth and a housing height; said tower width being less than said housing width and said tower height being greater than said housing height; said tower width being greater than said tower depth and said housing width being greater than said housing depth; said tower having a forward surface and a rear surface, and left and right side surfaces interconnecting said forward surface and a rear surface, left and right side edges defining said interconnection; said surfaces defining a chamber; said chamber being adapted to contain a computer adapted to control said display; said chamber being adapted to contain a power supply adapted to power said display; said computer and power supply creating a heat source; said rear surface being formed and arranged to define at least one aperture; closure for said at least one aperture being formed and arranged to define a top vent and a bottom vent; said rear surface defining a plane; said top vent and bottom vent being oriented one vertically above the other in the same plane; said chamber being adapted to contain a fan to move cooling air so as to transmit heat from said computer and power supply exterior to said chamber; said cooling air traveling on a first path passing generally horizontally after passing through said bottom vent, a second path generally vertically past said heat source, and a third path generally horizontally to exit said top vent; said computer being located between said top vent and said bottom vent so that said cooling air passes said computer; said flow direction being substantially limited to said first path, second path and third path and alternative paths being substantially limited; said display mounting apparatus further comprising a second computer mounted within the tower between the first vent and the second vent; and a second large format display coupled to a mounting arm and receiving signals from the second computer. ### Claim 2 (depends on 1) The display mounting apparatus of claim 1, said fan being controlled so as to operate continuously at or above a non-zero minimum speed so that a positive pressure is maintained within the chamber between the first vent and the second vent. ### Claim 3 (depends on 1) The display mounting apparatus of claim 1, wherein the computer is mounted vertically above the fan. ### Claim 4 (depends on 1) The display mounting apparatus of claim 1, further comprising a third industrial PC mounted within the tower between the first vent and the second vent; and a third large format display coupled to a mounting arm and receiving signals from the third industrial PC. ### Claim 5 (depends on 1) The display mounting apparatus of claim 1, wherein a thermostat controls the fan at the non-zero minimum speed when an ambient temperature is below about forty degrees Fahrenheit and at a maximum speed when the ambient temperature is above about ninety degrees Fahrenheit. ### Claim 6 (depends on 1) The display mounting apparatus of claim 1, wherein the thermostat is pulse-width-modulated. ### Claim 7 A display system comprising: an upright pedestal meeting IP56 weatherproofing standards and including a first vent for intake and a second vent for exhaust; said upright pedestal having one vertically oriented axis on a rear surface; said second vent is formed and arranged so as to be connected to said pedestal vertically above said first vent and on said axis; a mounting arm coupled to the upright pedestal; a controller mounted within the upright pedestal above the first vent; said controller being a heat source; said controller being positioned between said first vent and said second vent; a continuously operational fan mounted within the upright pedestal adjacent said first vent; a large format display having a display width, display depth and display height, said large said display being mounted outside the pedestal to the mounting arm and receiving signals from the controller; cooling said large format display being independent of said flow; said pedestal having a pedestal width, a pedestal depth and a pedestal height; said pedestal width being greater than said pedestal depth; said pedestal height be substantially greater than said display height; said display system further comprising a second controller mounted within the upright pedestal above the first vent; and a second large format display coupled to the mounting arm outside the pedestal and receiving signals from the second controller. ### Claim 8 (depends on 7) The display system of claim 7, wherein the fan operates between a minimum speed and a maximum speed to maintain a positive air pressure within the upright pedestal; a flow of cooling air entering said first vent horizontally inwardly and said flow changing direction vertically upwardly; said fan imparting movement of said flow vertically upwardly until said flow changes direction horizontally and outwardly so that said flow exits said second vent; said horizontally inward direction, said vertically upward direction and said horizontally outward direction being the substantially exclusive directions for said flow without dividing or substantial eddying. ### Claim 9 (depends on 7) The display system of claim 7, further comprising a thermostat that controls the fan at a non-zero minimum speed when an ambient temperature is below about forty degrees Fahrenheit and at a maximum speed when the ambient temperature is above about ninety degrees Fahrenheit. ### Claim 10 (depends on 7) The display system of claim 7, further comprising at least one gusset plate mounted within the upright pedestal above the vent. ### Claim 11 (depends on 7) The display system of claim 7, further comprising a third controller mounted within the upright pedestal above the first vent; and a third large format display coupled to the mounting arm and receiving signals from the third controller. ### Claim 12 (depends on 7) The display system of claim 7, further comprising a router providing communication between a remote network and the controller. ### Claim 13 A display system for use in an environment having a horizon comprising: a column configured to support one or more large format displays; said column being sealed so as to be weather resistant and including a first vent for intake and a second vent for exhaust; said column having one axis perpendicular to the horizon; said second vent is formed and arranged so as to be connected to said column vertically above said first vent on said axis; a controller mounted within the column and configured to send display signals to the one or more large format displays; a display housing is mountable separately from said column; a fan mounted within the column and positioned vertically below the controller, the fan operating continuously at or above a non-zero minimum speed to maintain a positive pressure within the column; said column includes said first vent positioned below the controller and a second vent positioned above the controller; said controller being a heat source cooled by air flow passing in said first vent and turning from a horizontally inward direction to a vertically upward direction with no substantial portion diverting to a direction other than said vertically upward direction; said air flow receiving heat from said controller while passing in said vertically upward direction; said heat added vertically upwardly ascending heat flow turning to a horizontal direction to exit said second vent perpendicularly to said vertical axis, with no substantial portion diverting to or from a direction other than said vertically upward direction, said display system further comprising a second controller mounted within the column above the first vent; and a second large format display coupled to the mounting arm outside the column and receiving signals from the second controller. ### Claim 14 (depends on 13) The display system of claim 13, further comprising: a gusset plate mounted within the column between the controller and the fan. ### Claim 15 (depends on 13) The display system of claim 13, further comprising a speaker mounted within the column and receiving audio signals from the controller. ### Claim 16 (depends on 13) The display system of claim 13, further comprising a router providing communication between a remote network and the controller. ### Claim 17 (depends on 13) The display system of claim 13, further comprising a thermostat that controls the fan at the non-zero minimum speed when an ambient temperature is below about forty degrees Fahrenheit and at a maximum speed when the ambient temperature is above about ninety degrees Fahrenheit.
