Haha didnt mean to offend you. By normal consumer I meant some consumer they are not bothered much by the technical aspect of a TV as long as the TV is good enough to watch under normal circumstances.

But if you have to ask what's the difference, the panel on the GX800 is brighter than the GX740. In the official spec from the website, the GX800 has Super Bright Panel Plus whereas GX740 has Super Bright Panel (not plus).

This simply mean the GX800 has brighter panel and produce great picture quality even under bright lit room. But not to say the GX740 is terrible, just the GX800 performs better. I hope this helps
