Gaming set to 1080p on a 4K monitor

[know of fence]

Look at the above pictures, aliasing is barely visible in the first, native res picture.

While with the scaled second picture from 1 foot away from your monitor you see aliasing jaggies around the high contrast edges of the face, ears, the nose. They disappear at about 2 foot away. That is the bloody difference! That's the kind of high contrast edges our brain uses to recognize patterns, and where resolution could be discernible.

Maybe we can all start an experiment and measure the individual distances at which aliasing becomes invisible. Distances will be lower still with higher PPI screens.

Being able to buy a 48" monitor or use a 48" 4K TV as you desktop, still would be nice.

I would hold off on a 4K monitor until next year. We should see them come down in price even more, have native support for HDMI 2.0 and DP 1.3, as well as having cured the early issues surrounding the scalars.

I have a 4k Panasonic TV with display port and it has a mode that scales 1080p by 4 pixels for perfect scaling. I haven't seen any pc monsters with this feature.

What reviews are you referring to? TFT shows input lag being pretty severe.

That's the review that got posted to the "2014 the year of 4k" thread here. I read it and thought I remembered another review claiming no input lag. Perhaps different firmwares or someone messed up on testing- not sure.

Weird that they can have such differences.

There is a 1 button HDMI device for 70 British Pounds (Leo Bodnar lag tester) that can measure input lag. AT's Chris Heinonen uses it even for 4K monitors, even though it puts out at 1080 test signal.

Measuring input lag in full (60 Hz) frames, like hardware.info does, is completely inadequate, that's something people tried before it was figured out. Also showing input lag results in multiples of 16,7 ms is stupid, or fundamentally wrong, it's an interesting thing to contemplate why, though it may go beyond the scope of this discussion.
