By limitations I mean the bandwidth provided by your USB ports will not work well with many games or anything that is graphics intensive. Not only do these options use up your USB ports, they also double up on using an adapter that will have limitations. Personally I would not recommend Option 4 or Option 5. Option 5 - Utilise two USB adapters and one Thunderbolt adapter and one HDMI adapter.Option 4 - Utilise two USB adapters and two Thunderbolt adapters.you could use one Thunderbolt > DVI adapter and one Thunderbolt > VGA adapter, and either of the HDMI or USB adapter options. Option 3 - A combination of options 1 & 2 above (i.e.Option 2 - Use a combination of two Thunderbolt > VGA adapters, one HDMI > VGA adapter, one USB > VGA adapter.Option 1 - Use a combination of two Thunderbolt > DVI adapters, one HDMI > DVI adapter, one USB > DVI adapter.I see the following solutions for connecting four of these particular displays: So the only problem you're likely to face is how you'd physically do this? If I assume you do, then you're in a situation where you want to use four external displays with a total of 5,242,880 pixels which is less than the official combinations supported by Apple. It's not clear from your question whether you were wanting to use the MBP in clamshell mode. However, this resulted in the MBP's fans spinning at more than double their usual speed when watching videos etc. I've also seen users connect three external displays while in clamshell mode. This is probably the limit of how much I'd recommend pushing things at these resolutions. This seems to work okay, although the fans do spin about 30% faster. 3440x1440) while also using the built-in display. safely using a single Thunderbolt display at higher resolutions (e.g.safely using two 27' iMacs in Target Display Mode (one using a Thunderbolt connection and the other a Thunderbolt/DisplayPort connection) without any problems (both in and out of clamshell mode).

3440x1440) with the MBP in clamshell mode without any problems whatsoever. Doing this results in about a 23% increase in the MBP's fan speed, but with no long-term damage/problems.

What I have seen instead are the following scenarios with the mid-2012 Retina MacBook Pro which uses the exact same setup (NVIDIA GeForce GT 650M and Intel HD Graphics 4000): I'm not aware of anyone who has tried connecting these MBPs to four displays at a lower resolution. However, unofficially you can exceed this. Officially these MBPs can support up to one HDMI display (at 1920x1080 pixels) while simultaneously connected to a Thunderbolt display (at 2560x1600 pixels), OR being connected to two Thunderbolt displays (both at 2560x1600 pixels). Hmmm, this is an interesting question because the monitors you want to connect to are only capable of a maximum resolution of 1280 x 1024.
