XR-48A90K - using a DVD with this TV

[Harry21]

I use quite an old Sony DVD player with this TV I recently purchased. I wonder if anyone can tell me DVDs marked 'ultra HD Blu Ray region free' can be used on this player, BDP S370, - or whether the benefits of the disk (especially picture) would not be apparent when using this particular player?

Hi @Harry21   It is not clear if you have an old BDP-S370 (2010) or thinking of buying one?

I think I bought it in 2015. Would there be any indication on it whether its old edition or never?
