4k vs HD

[pauland]

I am just looking forward to wimbledon, not really a tennis fan, but if/when it happens then things will be on the mend...

like behzad said - its a tricky subject... if You have a really expensive computer monitor, say at 4K native resolution, and you drop the resolution down to HD [1080p] then it will still look pretty good; but a cheap monotor will not

it sounds like you have a good TV

[as you may have noticed my implied point is - is the TV upscaling your video, or is it downscaling its resolution to match....]

LOL definitely not downscaled!

I sometimes take a picture from some TV programes because I want to keep a still reference. On every TV besides this one there's been a moire pattern - it's not present on the 4K set.

Here's the sales blurb:

• 4K UHD Processor: Powerful 4K UHD Processor Optimizes Your TV’s Performance by Upscaling Every Show, Season, and Scene With 4K Picture Quality
• Enhanced Detail with HDR: 4K Depth of Detail with High Dynamic Range Lets You See Shades of Color That Reveal More Detail than Hdtv Can Deliver

It's the top of the range of cheaper Samsung TVs.

Super pleased with it. I think the range has been superceeded in 2020 by the 8000 range.

there is a universal law that you cannot make a slik purse out of a sow's ear - that you cannot enhance beyond what is actually there....

what the TV is doing is overlaying the 1080p onto the 4K - now that is not downscaling in one sense, but it could be seen that way in another

the increase in the number of pixels that the 1080p source can use is a bonus.. but you are still just seeing 1080p, stretched neatly onto a 4k platform so to speak - the subtlety that a 4K original would have is not there because it never was

In the future that's not going to be entirely true because I expect at some stage to see AI processing working to such a degree as to go beyond pixel manipulation, but also shape recognition to resynthesize an image to what it thinks it should be. Of course, if there is no way of recognising what's on the screen it can't do that but I do expect it will synthesize say a chair leg using the low-res version to show a high-res equivalent - a bit like reading a fuzzy number plate and substituting a sharp one.

Hmm.

First of all I never claimed that "stretched" HD is equivalent to 4K.

The TV is doing rather more than using four pixels in place of one. It's resampling the image.

I'm not going to have an argument about it, the picture looks far better on the 4K set than it did on my old HD one and that's even true for the older SD resolution.

I'm an animator Paul - I know about resynthesizing stills to produce motion - ok that is not quite the same as your AI point - but extrapolation is extrapolation whichever way you look at it [pun intentional]

resampling is extrapolation, only as good as the algorithm in use; I'll grant there are some damn good ones in play today

Does your icons on your monitor go any smaller with a 4k monitor,? would love them to be a little smaller so i can fit more in. Especially with photoshop and spreadsheets

[behzad]

Belmare I don't have 4k but in win 10 you can change under Display, change scale and layout you can change the size of text , apps and other items

Dear Xara Designer Pro users,

We’ve heard you!! Our desktop application Xara Designer Pro+ (get more information here and here) is ready to take off into the universe of high resolution

Therefore, we’re in search of volunteers who want to test Designer Pro+ on their 4k monitors or HD Laptops for one week.

When: Testing starts this Thursday, 06/11 - next Thursday 06/18

How: Volunteers will get access to our Designer Pro+ HiDPI beta version. The beta-version has full functionality scope and you can use it the way you use your current Designer Pro version. Whenever you encounter a bug or problem, you can take screenshots and feedback it directly to us.

Interested? PM me here on TG or write an email to: evak@xara.com

We’re looking forward to having you on board!

Thanks,
Eva
