Hi guys

Apologies if im posting in the wrong area.

My Son has what is still a really good 42"panasonic plasma on his wal, he uses this for gaming and now wants to upgrade from his 360 to an xbox 1.....but the plasma isnt HD. The one we have in the living room is but i dont want to let him game on that one. I know any signal would be downscaled if he used the xbox 1 on his current tv, but is it doable? I assume you can get converters? and if so what do i need. His tv has the usual array of av scart and vga connections.

Would really apprecaite some guidence on this,

Thanks
