- I'm torn here. If I had purchased this solely for
TV use, it would be 5 stars all the way. As it is, I purchased it as a
PC monitor and here there are trade-offs, hence the 4-stars.
Yes,
this will do 4k@60Hz BUT not at 4:4:4 color. For the PC folks, 4:4:4 is
effecively 24bit color. I'm not a pro so I'm not sure if it's 4:2:2 or
4:2:0, but the yellowish fringing al ALL the single-pixel lines tells me
that it's not 4:4:4. Basically, if 4:4:4 where 24bit (8bits red, 8bits
green, 8bits blue), 4:2:0 would be more like 12 bits red, 6 bits green, 1
bit blue except that HDMI uses YUV which is luminosity (how bright),
hue (what color) and saturation (how washed out is the color). This is
because we are MOST sensitive to brightness, less to hue and less still
to saturation. The trouble here is that there isn't an equal amount of
data provided per color/sub-pixel and it can cause funny effects for
computer graphics that aren't noticed on video because video adjusts for
these variables AND is rarely as detail oriented in a unnatural way.
