Televisions of a similar age and type to this television have depths of between 4mm and 97mm. The TE32278B30CXD has one of the thicker depths (77 millimeters) amongst similar spec televisions of this age.
We compared this TV to all the other 77mm thick TVs and we think the Philips 32PFK5300 which has better reviews is also worth considering.
If you are not worried about having a thicker depth then you might want to consider the 32PFS6401 (£329) (77mm), or the 32PHH4200 (77mm) both from Philips.
What does "depth" mean?
