Surface Connections, Cables and Adapters
DVI (Digital Visual Interface) There are three variants of the DVI connector: DVI-A, DVI-D, and DVI-I. DVI-A is an analog-only connection HDMI Because HDMI and DVI are similar, you can convert from HDMI to DVI by adding the appropriate adapter DisplayPort The signal that originates from a DisplayPort can be easily converted to DVI by using a DisplayPort to DVI adapter. However, the inverse is not true. When you have to convert a DVI signal to DisplayPort, you must use a Dual-Link DVI to DisplayPort converter. You can also use a mini-displayport to DisplayPort adapter. VGA

Depends on specific adapter. May improve by holiday.

It has a pixel density of 216 ppi. Surface Pro 3 can support a single external display of up to 4096x2304 @ 24Hz. The i5 and i7 variants can support up to two external displays of up to 2880 x 1800 @ 60 Hz each, and three displays (internal display is off) of up to 1920 x 1200 @ 60Hz each. Be wary of Dual-link connectors - Signal strength is significantly reduced which lends to the fuzzy picture experience. There are also a few connections the video signal has to traverse when the signal comes through the dock which will slightly reduce signal strength.
Surface Pro 3 screen is used along with 1x or 2x 24 external LCD monitors. We see that the default scaling setting for the Surface Pro 3 screen is 150% However the default scaling setting on most external monitors is 100%. The issue seems to arise from the fact that the Surface Pro 3 (12 @ 2160x1440) has almost double the Pixel Density at 216ppi versus a standard external monitor (24 @ 1920x1080) at 91.8ppi. It appears that the ideal configuration when using the Surface Pro 3 screen and External monitors would be for the 24 monitor to render at 100%, and for the Surface Pro 3 screen to render at 150%. When the scaling is set to 100%, then all the UI elements appear very small on the Surface Pro screen, but appear normal on the 24. When the scaling is set to 150% then all the UI elements appear normal on the Surface Pro screen, but appear very large on the 24 monitor. We have not found a way to set different scaling levels correctly for different displays, it appears windows only using a single scaling setting for all displays, in a multi monitor extend configuration. This is with the Let me choose one scaling level for all my displays setting is not checked.

Use the custom resolution tool to add 1080x720 @60Hz to the SP3 panel: http://www.intel.com/support/graphics/sb/cs-029478.htm#hdgfx 2. Attach all your desktop monitors and use the Display control panel to switch the SP3 panel to the new 1080x720 landscape or 720x1080 portrait mode 3. Windows remembers all the different multi-monitor configurations (topologies) that have been used in the past. 4. Once you unplug those monitors, the SP3 will go back to the native 2160x1440 mode. 5. Result: hi-dpi when using the SP3 close to your eyes in tablet/laptop mode, and low-dpi when using it further away where you can't see the individual pixels
