resolution interview questions

Top resolution frequently asked interview questions

Maximum resolution through VGA/DVI/HDMI(/etc)?

I know the original VGA standard was meant to output 640x480 and that other standards over the original VGA connector are developed to output a higher resolution. (SVGA, XGA, etc.) But I was wondering if there's a specific limit to the resolution that the VGA connector can take.

Furthermore, are, and if so how are for example DVI and HDMI limited on resolution?

Why does 1366x768 resolution exist? [duplicate]

This question already has an answer here:

I know that there's a previous question about this but it doesn't have any real answers despite having been viewed 12,400 times, and the fact that it's been closed. With that in mind...

Why in the world is 1366x768 resolution a real thing? It has an aspect ratio of 683:384, which is the weirdest thing I've ever heard of while living in a 16:9 world.

All screens and resolutions I've been familiar with have been 16:9 aspect ratio. My screen, 1920x1080, is 16:9. The 720p that I'm familiar with is 1280x720, also 16:9. 4K that I'm familiar with, 3840x2160, is also 16:9. Yet 1366x768 is 683:384, a seemingly wild break from the standard.

I know there are plenty of other resolutions all over the place, but 1366x768 seems to dominate most of the mid priced laptop world and also seems unique to the laptop world. Why don't laptops use 1280x720 or something else as a standard?

What is the difference between 1080p, 1080P and 1080i?

Many times, I have seen resolution of 1080p and I know that it means 1080 pixels but I also have seen specifications on some HDTVs to be 1080i. So, I want to know the exact difference between them and whether 1080i video quality is available for the laptops too.

I googled and found out that at some sites, they mention 1080P rather than 1080p. Is there any difference between the two or they represent the same thing?

Rev1: Now I know that 1080p means 1080 horizontal lines of vertical resolution in a progressive-scan video

What are the differences of watching a 1080p and a 720p version of the same media on a 720p screen?

Say I have 1280x720 pixels on my screen and the current resolution is set to 1280x720 as well. What are the differences between the 1080p version and the 720p version of the same media? Is it noticeable to an end user (a non-video expert or enthusiast) ?

Clarification Edit: The question was in regard to .mkv file format rather than YouTube videos.

Dual monitors on Windows - How do I set a different DPI or text size on each monitor?

My laptop is a 15" wide screen running at 1600x1050, and in addition to that I connect an external 19" LCD which runs at 1280x1024. The problem with this setup is that if I increase the text size to make the laptop screen readable, the text on the external LCD is huge. Normal text on the LCD results in tiny text on the laptop.

What options do I have to get around this?

How can I take browser screenshots at a higher resolution than my browser supports?

I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 4000x3000 pixels. My laptop's screen has a native resolution of 1400x768. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work?

Set DPI of individual applications in Windows

Is it possible to set the DPI of individual applications in Windows?

I want to increase the DPI of one or more applications but not the entire system.

Can this be done?

Windows 7 display profiles shortcuts for switching monitor setups

I have 3 monitors attached to my 8800GTS, which can only use 2 at a time. I use 3 different setups:

  • single screen (1)
  • dual screen (1+2)
  • single screen + TV out (1+3)

having to click screen resolution and select different screens etc is a bit of a pain, and to get round this I used to have an autohotkey script that opened up the NVIDIA control panel and select a different profile. However in W7, for some reason everytime I select a new profile it seems to mess up all the settings/not work at all.

I was wondering - does windows7 have any built in commands for selecting monitor 1+2, or 1+3 and just 1?

I'd love to have 3 shortcuts on my start menu like I used to!

On Ubuntu 9.10, where is the xorg.conf file in Karmic Koala?

I am trying to change this xorg.conf file that I used to modify under Ubuntu 9.04, so it can have the higher resolutions of my monitor. Under 9.04, the monitor was unknown, and I had to key in all resolutions in the file, and although it is found under 9.10, 9.10 does not have the highest resolution that my monitor can sustain.

How can I change such a setting? Is xorg.conf moved, or replaced?

Remote Desktop Zooming

Using Remote Desktop from a device with a hi-res screen (say, a Surface Pro) is decidedly tricky - as everything displays 1:1 scale and so looks tiny.

If the machine you are remoting into runs Server 2008 R2 or later, you can change the dpi zooming setting (see here).

But for older hosts, that doesn't work.

Using normal Remote Desktop, you can connect with a lower resolution, say 1280x768, and turn on smart-sizing. However smart-sizing can scale down (to display a huge desktop in a small area) but does not seem to scale up (to display a small desktop in a big area).

Using the Windows 8 Remote Desktop App, you can zoom - but you cannot set the default resolution of the host.

What I want is a lower resolution in the host, scaled up to fit my screen.

So both of those are close to what I want, but dont quite work. So question is:

Does the Remote Desktop App allow screen resolution to be set somehow? Is there some other Remote Desktop client that can handle zooming better?

Aging eyes, screen size and resolution

I have a 19" monitor with a native resolution of 1600x900. This provides crisp clear text, but it is too small. My vision is not as good as it once was. In order to see easily I have reduced the resolution to 1280x720 and have chosen LARGE fonts. The text is larger but not as clear and it makes me scroll my screen horizontally because it doesn't "fit" the screen

If I graduated to a 23" monitor with a native resolution of 1920x1080 with a normal font would that fix my woes? How would the text size on my 19" 1280x720 LARGE font compare to the text size on a 23" 1920x1080 with regular font? .

Ubuntu on VirtualBox can only show resolution of 800x600 - how do I change it?

My monitor is 1920 x 1200 and the computer is running Windows 7.

Using VirtualBox and Ubuntu 10.04, the screen of the Ubuntu can only be 800 x 600 or 640 x 480. Is there a way to change that.

I resized the VirtualBox window and Ubuntu still thinks the max is 800 x 600.
