Wallpaper Quality?

Hello, I'm not the one who usually makes threads, but I'm just installing Windows 8 onto my Virtual Machine, and I noticed the default wallpaper is very low quality. I have OCD (I know, pftt), and I just can't imagine them shipping Windows 8 with a wallpaper like this. I'm just wondering, is it just me? I even looked up the default wallpaper online and saw it's the same quality (thinking it was virtual machines problem, but I was wrong).

If you look closely around the edges of the flower, you'll see the degradation. I know it's supposed to be some kind of blue that makes the effect that there's a breeze in the picture, but it really doesn't do it's justice.

Other than that, I love the OS. I'm just being nit picky, but the fact this made it into the RTM, I'm not very happy at. I worry about every little detail, I know I can just change the wallpaper, but this default wallpaper will be rolled to millions/billions of PC's...

I'm not complaining, I'm just shocked.. other than that, I love the new OS.

If it's intentional, then I wish they didn't do it :(, here's a 4 x zone of the most worrying part for me:

You don't know much about photography, huh?

http://en.wikipedia.org/wiki/Bokeh

This is completely normal and not a quality issue.

Yes, I know a little. I've seen Bokeh in the past, but I haven't seen such intention in past images of Bokeh applied photos. I might add that the other flower and parts are fine, it's just this area.

Quick question.

For how long will you be looking at this image? Surely when working/using your PC you don't see your wallpaper for 90-95% of the time.

Depends, I know I can just change the wallpaper. I was just glancing at it yesterday and thought it looked a little off. I'm very nit picky :p

I agree, the default wallpapers for Windows 8 are low quality. For starters they're all 1920x1200 (or the corresponding multi-monitor equivalent), so they look even worse when stretched to 2560x1600; they're also JPG rather than a lossless format like PNG. More importantly, they're all overly artistic and utilise excessive amounts of blur.

Personally I have a membership with Vladstudio because I love the wallpapers he has there - everything from cartoons to photos. I know wallpapers are very subjective but the problem with Windows 8 is that the included wallpapers are all very similar in style and objectively bad quality due being low-resolution JPG files.

How so? It looks to make like an intentional use of single focus photography.

That image clearly shows color replacement around the edges of the changes in color, as you would see then choosing a "Save for Web" in Photoshop and choosing a quality lower then 100% which then replaces/removes colors in the palette.

I've just noticed that, depending on how well your monitor reproduces colour it depends how much degradation you'll see. I've just plugged in another Samsung Monitor in, and it looks pleasant. The monitor on my Air which is also Samsung, shows the flaw more clearly, but I'd say colour on the Air is a lot better then this monitor :s. Think I'm going to calibrate to see what I can do.

Correct there is image compression. I never claimed otherwise. I was referring to the 'blur'. That's obviously an artistic choice regarding the focus used while shooting the image.

I beg to differ. The diagonal lines across the flower are consistent with a Tilt-Shift blur done in PS CS6.

It's a combination of the two - there's the excessive blur and post-processing (which is artistic); and there's the compression artifacts (which stem from the low resolution and lossy format). The end result? Wallpapers that are objectively low quality and stylistically objectionable.

Diagonal lines? I see standard image compression, but I don't see those, and I'm on a professionally calibrated monitor. Normally I'm the person who tears these images apart if I spot poorly handled PS work.

I actually discovered this just the other day. The OP is right - Windows automatically compresses your wallpapers when you set them. At least it does when you use custom wallpapers - I'm not entirely sure how Microsoft does it for the default ones. It stores the compressed file in C:\Users\[username]\AppData\Roaming\Microsoft\Windows\Themes - you'll notice that "Transcoded wallpaper" is significantly smaller than whatever the actual image is.

Through some trial and error I've found a way around it though. Assuming your wallpaper is a .jpg, you first have to convert it to a .png (I use the Gimp or probably even Paint works). If it's a jpeg then Windows will always compress it. How you need to set the background so that it's lossless seems to depend on your OS:

For Windows 8: Once it's a png you can just use File Explorer and right click -> set as desktop background. You can also use the Personalization menu from the desktop.

For Windows 7: The only way I could get it to not compress was to open the png in Firefox and right click -> set as desktop background. This works in 7 but creates artifacts in 8 - it's weird. I primarily use 8 so I haven't tested 7 as much.

The jpeg artifacts are particularly noticeable with vector art. I use this image is a test: http://fwallpapers.c...-background.png

You can see it for yourself - save it and set it via Windows Photo viewer - you'll notice the orangish curve in the middle has noticeable jpeg artifacting (even though the source is a png). Then try setting it via File Explorer (assuming Windows 8) - it's completely lossless. The artifacts usually aren't that noticeable - especially with nature photos and stuff; I'm just pedantic about my desktop backgrounds.

Edit: Huh, I thought using File Explorer caused compression for PNGs in Win8, but apparently it doesn't. I think it still does in Windows 7 though. The important part is converting it to PNG. Then just play around with different methods of setting it until the artifacts disappear.

    • SpaceX reportedly plans a Starlink mobile service for U.S. consumers

      By Karthik Mudaliar · Posted

      SpaceX reportedly plans a Starlink mobile service for U.S. consumers by Karthik Mudaliar SpaceX reportedly wants to sell mobile phone plans directly to consumers in the United States as part of a wider expansion of Starlink. According to a report from the Financial Times, SpaceX president Gwynne Shotwell discussed the plan with investors during the company’s recent IPO roadshow. The company is also said to be considering building a terrestrial mobile network to complement Starlink’s satellite coverage. The plan is quite different from how Starlink currently operates in the U.S. mobile market. SpaceX already provides satellite connectivity for T-Mobile’s T-Satellite service, but T-Mobile remains responsible for the subscription, billing, and customer support. A Starlink-branded mobile service would give SpaceX control of the customer relationship instead. It could also turn the company from a partner of traditional mobile operators into a direct competitor. T-Mobile also began testing its Starlink-powered satellite service in early 2025. The beta was initially limited to text messaging and was also available to some AT&T and Verizon customers. The service has since expanded to support limited data access through selected apps, including WhatsApp, Google Maps, AccuWeather, and AllTrails. It is designed to provide a connection in areas where normal cell towers are unavailable, rather than replace a conventional mobile network. However, if SpaceX actually has a plan to serve nationwide, it needs to do more than just satellite networks and actually support on-ground operations. It can also partner up with existing carriers and become a mobile virtual network operator (MVNO). With that said, SpaceX has already spent heavily to support its mobile ambitions. Just last year, the company agreed to acquire wireless spectrum licences from EchoStar in deals worth a combined $19.6 billion. EchoStar's spectrum includes AWS-4, H-Block, and AWS-3 frequencies that could be used for both satellite and terrestrial communications. According to a SpaceX securities filing, the Federal Communications Commission approved the transaction in May 2026, although it is not expected to close until late 2027. There's no official statement by SpaceX for now. Pricing, availability, and other details remain unknown. Source: Financial Times

    • The Trump administration doesn't want you to use OpenAI's GPT-5.6 without its approval

      By David Uzondu · Posted

      The Trump administration doesn't want you to use OpenAI's GPT-5.6 without its approval by David Uzondu Image via @realDonalTrump (X) As OpenAI prepares the release of its next model, GPT 5.6, the White House has instructed the company to limit the distribution of the software to a small group of government-approved partners instead of the general public, as it has done with previous releases. According to The Information, OpenAI Chief Executive Officer Sam Altman sent an internal memo to staff on Thursday explaining that the federal government will approve access "customer by customer" during an initial preview phase. Altman noted in the communication that this restrictive rollout is "not [their] long-term model" for software deployment, and the company plans to work toward a "more sustainable" distribution method later. CNN said that both OpenAI and the Trump administration view the capabilities of GPT 5.6 on the same level as Anthropic's Mythos and that government officials intend to "collaborate with frontier AI labs to develop shared approaches for addressing the challenges of scaling this technology." The latest restriction comes just weeks after the US Commerce Department decided to restrict Fable, a version of Mythos with extra safety "guardrails" to prevent users from exploiting software vulnerabilities. Not long after the release, though, researchers at Amazon found a way to bypass these restrictions, prompting an aggressive response from federal authorities. The government ordered Anthropic to cut off access for non-US citizens located outside the US, non-US citizens living inside the US, and incredibly, even Anthropic's own foreign-born employees. Anthropic now appears to be building a workaround to resolve this compliance block with an update to its Privacy Policy that introduces a category called "Verification Data" to handle KYC and Digital IDs. This setup could mandate digital identity checks to filter users by nationality, requiring a government-issued ID and facial biometric data. Who knows? Maybe in the future, you would have to scan your US Passport or State ID to prove your citizenship before you are allowed to chat with Fable 5 (or any other model).
