Yes there is but as I said before it is more expensive/hassle that just buying a new freeview+ box.
First you'd need something like this:
http://www.amazon.co.uk/RCA-SCART-Ad.../dp/B0035XB4Z4 (yellow connector is composite video)
Edit: this connector might actually be the wrong direction. You'd want one that goes from SCART to composite or s-video)
Then:
http://www.amazon.co.uk/dp/B00083Y72...SIN=B00083Y72Q
(Note you need Composite to VGA NOT VGA to Composite) First one I found with a quick search, might be able to find some cheaper ones but, remember, it must be composite to VGA not the other way around (vga to composite converters are super cheap but are useless for what you want to do)
Of cause you'd still need some way to listen to the sound which now would be in the form of a L+R audio on the white and red plugs on the RCA/SCART adapter.

The signals are exactly the same actually. Both VGA and SCART use component video signals. The only difference is the horizontal frequency output by the device. It is perfectly possible for a VGA monitor to display output from a SCART device if it accepts the horizontal frequency. However, in this case the monitor does not.
Also you'd be surprised at the amount of TVs that still do post-processing even if you tell it not to/configure it yourself. Although I'm not denying you can get better quality panels in TVs than some monitors.
