Windows 8 – The settings for the Samsung UE590 4k resolution can not be set to 4k

I just bought a Samsung UE590 Ultra High Definition 4K monitor.
I am using Windows 8.

If I go to my resolution settings for changing the screen resolution, a maximum of 1920×1080 can be selected.

Should not I be able to select up to 3840 x 2160?

Is this a limitation for my video card?
I checked my video card and it says:

Adapter Type:Intel (R) HD graphics

Total available graphics memory: 1664 MB

Dedicated video memory: 32 MB

This link here suggests that I should set up a "custom" resolution, but this option will not appear in the "Resolution Settings" dialog box in the Windows 8 Control Panel.
The maximum available resolution is 1080×1920 when connecting a UHD monitor with HDMI

Aftermarket lens for Yi 4k + action cameras

I have a Yi 4k + action camera and am on vacation overseas. I want to replace the standard lens that I believe is 150 ° POV because it has too much distortion.

Pixaero makes aftermarket lenses. But I'm having trouble deciding which lens to buy. The website strongly suggests a 3.4mm lens, which corresponds to a focal length of 18mm. That still sounds like a lot to me. Although the lens requires less than 0.5% distortion.

I thought that their 6mm lens would be better, because it has a focal length of 35mm.

I know that the first lens is good for landscape and wide-angle shots. But what about the middle and closer? The other problem is that the 3.4mm lens is 30% more expensive.

I used the standard lens to try taking a photo at an air show, but the plane was no bigger than points in the air. Will the 6mm give a decent video in all areas? Does the 3.4mm really have such an advantage.

Web Hosting – 4K high-bandwidth wallpapers app

I've got a wallpaper app with 10k + wallpapers with at least 1 MB for each wallpaper. The app is under test. Lately, I've noticed that only I needed around 15 GB of 1 TB bandwidth from my hosting plan for testing this app during a few days. The app brings wallpapers with specific API from my database, so what do you suggest to me to solve this problem?
Sorry, I do not know if this is the forum to post my question. Remember that and my bad english thank you.
Since Mr.Stephen Ostermiller has asked the website (server) is just a backend server that users can not see. It is only available via URL as an admin panel to upload or delete or manage wallpaper in general. I monitor the traffic through my apache2 access.log There are no unusual actions, and to make sure the app's cache is really big, I can delete it anytime after I use it. I think it's just my traffic.

Youtube – 4k 60fps – Deleting images (stutter / lag / freeze)

I try to see 2160p (4k 60fps) content on Youtube, but I experience a lot of frisky frames … d. H. The video freezes / stutters completely (the sound is fine).

The youtube example I use: Costa Rica – 4k 60fps – Youtube

If I look at the video in 1440p, it will play smoothly without dropped pictures. When switching to 2160p, however, the video is stopped / stuttered due to the large number of dropped frames (80%) (see below).

Exuberant pictures - 28 sec. - Youtube 4k 60fps

Therefore my internet (via cable) is stable and ok and I use the VP9 codec in combination with HTML5 and Mozilla Firefox / Microsoft Edge (same result). I do not use hardware acceleration.

My PC specifications:

  • MSI H97M-G43
  • Intel Core i5-4460 Boxed
  • MSI GeForce GTX 1080 GAMING X 8G
  • Crucial Ballistix Tactical BLT2C4G3D1608ET3LX0CEU
  • Seasonic M12II Evo 620W
  • LG 27UK850-W silver
  • Windows 10 Education (is Pro version) – Version 1803 – Build 17134.590
  • Nvidia driver – (NVIDIA 417.71)

So in my opinion it should be enough to watch 2160p videos on Youtube. The CPU is a bit stressed, but the load is 80%. The GPU barely runs because 2160p content requires a lot of decoding from the CPU.

Electricity (after 28 seconds) – Min – Max:
CPU - 28 sec. - Youtube 4k 60fps

Does anyone have any idea what is wrong / how to fix it (software setting or is it really the CPU)? Thanks for all the information!

Display – Does the Macbook 12 Inch (2016) support the output of 4K 60 Hz to an external monitor?

I have an ASUS PB287Q monitor. I connect my Macbook 12 Inch (2016) to Mattis via a Mini DisplayPort cable and a Belinda USB TypeC Mini DisplayPort / Mini DP adapter to the monitor.

In this configuration, I think a refresh rate of 60 Hz with a resolution of 3840 at 2160 can be obtained.

System Report - Display

I have also done the UFOTest and it seems that my refresh rate is 60 Hz from the result on this website.

UFOTest result

However, according to the official specification from the Apple website, the Macbook 12 Inch (2016) should not offer a resolution of 60Hz at a resolution of 3840 with 2160. It should be at max 30Hz.

Enter the image description here

So is it a true 60Hz refresh rate, which I get in a resolution of 4K (3840 x 2160), or do I get wrong information about the refresh rate from two different sources?

Am I missing something?

Can the Xiaomi Mi Box 4K stream videos from an external server using SMB or FTP protocol with external subtitles?

I'm seriously considering moving from my Android TV-based Flix TVBox player to the Xiaomi Mi Box 4K, as my current solution for playing / streaming video from an external server via the SMB or FTP protocol with external subtitles is not completely works.

Some software players (i.e., VLC) can browse network shares (others do not), but all fail when opening external subtitles, ie. H. They are stored in the .srt or .txt file with exactly the same file name as the corresponding video file. Subtitle viewing is only possible if embedded in video files that support embedded subtitles (such as MKV) or subtitles downloaded from

This is especially weird as it only happens with the SMB / FTP protocol. If you use exactly the same player on the local hard drive, everything works like a charm.

I would like to ask how it works with the Xiaomi Mi Box 4K?
