4k tv with Chroma 4:4:4 under $600
I have $500 in Amazon gift cards and are able to pay $100 extra for a 4k tv to use as a monitor for my laptop (for audio/video editing and some writing) so I think it would be best to have a tv capable of Chroma 4:4:4.
My eyes are on the 40-inch Samsung 6500 which was under $600 a few weeks ago but right now is over $700 including tax which is too much for me so I'm open to other brands. Smart capability is not really important.
Also important: Since I would like to use my Amazon gift cards it would have to be pricematchable (is that a word? ;-) to Amazon.
Thank you for hints and tips.
PS: As a non 4:4:4 I have the Seiki 4k 42-inch but I'm not sure if that's really usable for what I do (I work long hours) so feedback on that would also be really appreciated.
