What does xga resolution mean




















The first option is to stretch the content to the aspect ratio of the screen, but this distorts the image and rarely produces good results. The second option is to display the content in a letter box. This means that the content is displayed in it's proper aspect ratio with black bars in the unused areas of the screen as shown on Figure 4. When the resolution is annotated by numbers it's pretty easy to determine what is low and what is high, but very often the industry uses abbreviations that they understand, but that might be quite confusing for some users.

So let's talk about the most common screen resolutions for mobile different devices and clear the geek lingo in the meantime. Figure 5. VGA was the first video graphics standard to become common and a lot of the new ones are based on it. It was first developed for computer monitors, but nowadays these resolutions are considered as pretty low and even smartphones usually come with resolutions from the higher end of this standard and the newer flagship devices even go beyond.

In the beginning the aspect ratio was the base of everything, so the standard VGA resolution of x has that ratio. So VGA is the base and it's used as a base of other lower or higher resolutions.

Going into lower resoltuions, this standard resolution can be modified to have half or quarter the pixel count. You will notice that the numbers don't need to double for the resolution to double and every time the numbers double the number of pixels quadruples like on Figure 5. This means it actually has four times the pixel count of VGA.

The resolutions that are part of the XGA are nowadays used for computer monitors and tablets while QXGA might be used in higher end computer monitors only while tablets haven't really reached them yet. HXGA is a standard that is currently being advocated for for ultra high resolution ussages. It's important to note that modern TVs and some of the mobile devices and even computer monitors use the HD High Definition standards instead of the VGA variants despite the fact that some resolutions might be very similar.

HD will be covered in detail below. All of the resolutions in this group are quite popular not only in TVs, but also in mobile devices like smartphones and tablets and of course, some computer displays. Actually all of the high definition resolutions use the aspect ratio which makes it a far clearer standard than VGA, XGA and so on.

It can be viewed as a building block for the rest since if you put 4 nHD frames in a 2x2 arrangement, you will yeald a resolution of p and if you arrange 9 nHD frames in a 3x3 arrangement, you will yeald a resolution of p. Additionally, this standard provides options for resolutions that are even higher, which are usually used in high-end TVs, smart TVs and 3D TVs that require very high detail.

All the resolutions part of the HD standard can be viewed in table 5. Figure 6. The correlation between different resolutions' sizes pixel count and aspect ratios. When I had cataracts I played with the resolution on my monitor considerably, trying to find something I could read without glasses.

Coupled with changing the font size, I finally found a setting, but writers beware! After eye surgery I'm back to a normal resolution on the screen, making sure that it matches the screen aspect ratio. I use a large monitor plugged into a laptop, and the monitor doesn't match the laptop ratio, so I have to reset it on the rare occasion I go mobile with the computer if I want it to look right. Personal Finance. Welcome to HubPages. Table 1. So far, so good. The confusion arises when you take the aspect ratio into the equation as well.

Mix this with higher-resolution devices your laptop may have an HD screen already and the normality in meeting rooms that bigger is better and the demand for full HD or higher is truly warranted. Full HD projectors — or p — have become incredibly popular, while 4K UHD resolution is now no longer the preserve of cinemas but can be found in office projectors and of course, top of the range home cinema projectors.

However, there are great value options at each level that make it easy for users to stick within their budget while achieving the best image quality possible. Moving further up the scale, some Full HD home cinema projectors can cost well into the thousands. If you move from here into the bottom end of the 4K market, will you still be getting everything you need?

Check out the tables below for a comparison. The thing you need to remember is that every projector has a "native" resolution sometimes called "true resolution";.

That's the maximum number of pixels it can actually project. So an XGA resolution projector can only display , pixels at a time whereas a UXGA resolution projector can display 1,, pixels and a native 4K resolution projector jumps all the way to 8,, pixels.

It also affects the compatibility of your projector with your computer and how efficiently they work together. If your computer is sending a signal to the projector that is WXGA and your projector has XGA resolution, this causes a bit of a problem.

Most projectors have the compression technology which we explain below, so you'll still see an image. Most computers sold today run in p resolution as standard, but the market is quickly moving towards higher output resolutions. Spend the time checking your input devices resolution to match it up to your projector where possible.

However, to cope with it they will "compress" and adapt the image that is received into fewer pixels. The result is that some of the original pixels are "shared" across the same pixel that the projector displays. This is less important with photos and video because you don't notice it so much, but with text, it's a very different story. In short yes but the honest answer depends on what you need the projector for. S-PVA panels all use true 8-bit color electronics and do not use any color simulation methods.

Hi, I am planning to buy a dell latitude laptop and I have the option to choose between xga and sxga screen,but I am confused with the type of screen I should go with. Please advise which one I should go for. Regards, Arindam. In reference to article , WVA means wide view angle, nothing more.

WVA is defined at least be HP as being a viewing angle greater than degrees. WVA has nothing to so with resolution. Your email address will not be published. April 20, at am. Omar Barakat says:.
