Unable to set a higher resolution

Since I’m new I couldn’t comment on this post. I’m stuck, thanks in advance.

Below is the information:

image quality – What approximate resolution did Beta SP correspond to?

I know you can’t really say that a non-digital format such as VHS and Betacam (or LP for sound) have a resolution but it should be possible to give an rule-of-thumb estimate, shouldn’t it?

Wikipedia gives some number (300 for Beta and 340 for Beta SP) but that sounds too low doesn’t it? PAL and NTSC was 575 and 625 lines and Beta (SP) was used for that, wasn’t it? Why this discrepancy?

display – Increasing resolution for external monitors

I am running Ubuntu 20.04 on XPS 15 7590 and I got two 27″ Samsung Monitors that are docked to my laptop. While my laptop easily gets a resolution of 3840×2160 (16:9), the 2 monitors only get 1920×1080(16:9).enter image description here

And due to this, everything in the monitors is incredibly zoomed in.

Is there a fix for this? I should get better resolution on 27″ monitors than my 15″ laptop.

display – ask for solution: using macbook pro 13′ (2019) in lower resolution in windows (1280×800)

I know the native resolution for MacBook pro 2019 is 2560×1600. using this resolution makes every thing very small in windows 10 and its needed to use scales (for example 200x).
another solution for this could be using lower resolution.

Using 1280×800 seems perfect because it is exactly half in each dimension and it is expected that it does not need any adjustment because each four pixel maps to one pixel in this resolution.

but it seems there is a problem in firmware of LCD controller of MacBook that makes the screen blurred in this resolution.

any solution would be appreciated.

3d – Proper sphere to triangle collision resolution

I am working on a 3D game. For simplicity sake, the player is currently represented as a sphere. I have implemented an intersection test between a sphere and triangle, which returns a packet containing the collision depth and normal.

Simply moving the sphere along the normal with a magnitude of the depth works fine, but there are several problems. Sometimes the player just clips throught corners and walls, and you cannot go up slopes, since gravity is pushing you down.

I’ve also tried combining the collision normal and depth of all the current interesctions, although this doesn’t make any difference.

There is no problem with the intersection code, I just want to know how to handle the collision in a fool-proof way.

display – MacBook Pro (16″ 2019) Does Not Recognize Correct Resolution

I’m having a rather annoying issue with my MacBook Pro 16″ 2019 device since upgrading to macOS Big Sur. Every time I plug my device to my 4K monitor into the device (via USB-C to USB-C, or USB-C to DisplayPort), macOS will show a maximum resolution of 1600×900 but my monitor’s recommended resolution is 3840 x 2160.

Photo shows the Display setting screen, with resolution of 1080p selected

I currently have a workaround to resolve the issue which is the following:

  1. I switch from 1080p resolution to 1600×900
  2. Un-plug the cable, and plug it back in again
  3. Then switch to 3840×2160

This process can be tedious and take a while to complete (between switching resolutions). Is there any solutions which people are aware of?

These are the details of the device and monitor

  • macOS Version: 11.2.3
  • Model: MacBook Pro (16-inch, 2019)
  • Processor: 2.3 GHz 8-Core Intel Core i9
  • Graphics: AMD Radeon Pro 5500M 4GB
  • Monitor: BenQ EW327OU

These are the things which I’ve done to date

  • I can’t pin the issue on the monitor, as I’ve been using a MacBook Pro (2017) with the monitor for a week or so without a single problem.
  • Used ColorSync to repair any issues with the monitor profiles
  • Used various other cables such as HDMI, USB-C to USB-C and USB-C to DisplayPort.
  • Reset NVRAM and SMC
  • Re-installed macOS
  • I can’t reproduce the error in Windows via Bootcamp, so I’m confident it’s OS related.
