Full HD & HD Freeview. Great reviews. Also 51 'customer reviews' at Amazon, of which 43 are 4 or 5 Stars. Currently nothing to touch it for picture quality at this price.
Of particular value is that there's no Panel or Processor 'lottery' with the 40RV753. It contains an S-PVA panel & Toshiba's own processor, which is superior to pretty much any other used by sub-£500 TVs.
There's no home delivery service for this deal, so I don't think you can get 10% Quidco Cashback, as it doesn't apply to 'reserve & collect' deals.
Note that it's not 'LED' or 100Hz, & it doesn't have Netcast.
