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?

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?

How can I change the system font size in OS X?

I'm using a Mac Mini on big flat-screen TV for playing media. The small font size is really annoying when sitting far away. Is there a way to increase the system font size in OS X?

Why does text look so Horrible on my HD monitor?

I just bought a 1080p 22" Samsung Syncmaster 2333HD (connected via HDMI) and the picture and video quality is great but the text quality is absolutely horrible. This monitor has a built in HD TV tuner.

Even as I type now all the text in this text box as well as in the browser toolbar and start menu, etc looks weird - like it all has a white outline around it that makes it jagged and hard to read. It hurts my eyes just to look at it.

I am running my PC in the suggested native resolution of 1920x1080, so what's the problem?

Is this one of the unavoidable downsides of using a HD monitor? Is there a solution to the problem?

Why is vertical resolution a multiple of 360?

YouTube recently added 1440p functionality, and for the first time I realized that all (most?) vertical resolutions are multiples of 360.

Is this just because the smallest common resolution is 480x360, and it's convenient to use multiples? (Not doubting that multiples are convenient.) And/or was that the first viewable/conveniently sized resolution, so hardware (TVs, monitors, etc) grew with 360 in mind?

Taking it further, why not have a square resolution? Or something else unusual? (Assuming it's usual enough that it's viewable). Is it merely a pleasing-the-eye situation?

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?

Can I take a screenshot as vector graphics or at a higher resolution than native?

I need to take some screenshots of an application window. My laptop resolution is low, and I'd like to get high quality images.

Is there a way to grab the screen as vector graphics (e.g. EPS, PDF, SVG)? Alternatively, is there a way to take a screenshot with higher resolution than the native one?

My native resolution is 1366x768, while I'd need at least a resolution of nearly 4000x3000.
