He I wrote somewhere that the one on one seemed to be independend on contrast but when I come to it I will look into the tube i looked at the screen. It certainly did ot get worse at low contrast maybe better at 720p not sure.

Red,
I forgot. Do you have a signal generator?

I do have a scope 150MHz and a 1 MHz digital signal generator and a 20 MHz analogue generator but no testpicture generator. Wish I had one because I suspect the input is filtered as it should be.

I watched tv on my screen for several years @720p in my living room. Was ok for me. Now it's time to switch to 1080p.
4K would be (maybe) the way to go in my dedicated home theater as the screen will be around 3m in width. |
While Kal agreed partially, i dont really agree at all. I have a 28" 3840x2160 screen on my PC, the difference is massive between that and a 27" 1920x1080, and even still noticably better than simular sized 2560x1440.
Despite the lack of content in terms of movies, those still look better due to no visible screen door, but for PC gaming or UHD photo viewing the difference is EASILY noticable, even from a distance.
To say it only makes sense of bigger screens is somewhat of an interesting statement, one could be led to believe you havent spent much time infront of one or you plain just dont have the eye sight to notice the difference, you wouldnt be alone on either of those, but in my experience i could not go back to anything less and still remain happy with the image quality.

Doesn't this really depend on how close to the screen you are. Really high definition makes sense if you are really close to the screen.

Yes and no, but like i said though, the difference is still quite obvious even at 3 meters

Case, when you compare those monitors, are they in all ways identical, except resolution.?

I thought Sony VPL-VW300ES would be a JVC killer with "only" 7000 Euro on the price tag, but apparently its missing out on a dynamic iris system. At least the prices are coming down a bit.. anyone at CEDIA should have closer look at this beast.

No, the two lower res monitors were IPS, one was $1,100, the UHD monitor i have is a TN, and still considerably better to look at.
If i compare to a TN FHD, the difference is HUGE.

Case,
So you are saying you can see a difference at 120" distance on a 28" monitor?
Wolf,
I believe the US isn't getting the 300. There has been mention of another pj, but that is all I have.

That's to bad, I would have loved to hear about it. Ah well, maybe someone in Germany has been to IFA and seen it.

Yes, i am, i thought i made that reasonably clear so im not sure why you would question it. And its obvious to my eyes. Id be really amazed if no one else can see the difference.
I have compared using a slide show of UHD still images.

The funny thing is I get this same effect tha people often describe as looking through a window at 720p when the CRT bandwidth is increased. I have seen a very big UHD screen and I was suprised too by the looking through a window effect with UHD source material. I think the lack of screendoor with digital leads to the same effect as the increase on bandwidth with CRT. I think I see it but I would have never believed it.

A very good graphic designer i know well also said she could clearly see the difference, even at that 2-3 meter range.

One thing I also noticed but I have only seen a few that is was very smooth but there was not much 3d effect. In the demo I saw a woman was walking in front of a wall. Both very sharp and as if two 2d movies played on each other. Everything was focused too. There was no single depth. But it could be the source material or the way it was filmed?

No idea, i have seen a couple demos in shops, some looking much nicer than others.
I used still images i downloaded from a couple different UHD websites and put them on slideshow.

with UHD material you have a 1080P color resolution, what happens if you put 1080P color resolution to blu ray.?

Not sure what you mean there. Do you mean set it 4:4:4?
