Native Resolution

A projector's Native Resolution is the number of pixels the projector uses to create the image. The more pixels it uses, the higher the resolution.

Resolution is quoted in two numbers, such as "1920x1200," where the first number refers to the pixels horizontally across the screen, and the second number refers to the pixels vertically from top to bottom. This particular 1920x1200 resolution is also referred to as WUXGA. Each numeric native resolution format has a name like this to shortcut the need to quote the numbers. The names don't make much common sense but there are only a few of them in popular usage so they are easy to remember once you've gotten used to them.

How much resolution do I need?

High-resolution projectors are able to show more complex picture detail than low resolution projectors. In addition to giving you more acute image detail, since there are more pixels used to make the image, each individual pixel is smaller, so the pixels themselves become less visible on the screen. However, you will generally pay more for higher resolution.

Lower resolution projectors are much less expensive, but they can produce images that are just as bright and attractive as higher resolution machines. Unless you have a specific need to display complex images with a lot of fine detail, buying a lower resolution projector will be your best bet from a cost perspective.

Native Resolution Options

The current standard HDTV resolution format is Full HD 1080p, which is 1920x1080, a 16:9 format. This of course is the most popular resolution for home theater projectors, but it is no longer just a consumer/home theater format. Many people are buying HD 1080p projectors for business as well. There are many dozens of native HD 1080p projectors putting out over 5000 lumens for commercial and business use Here is a list of them: HD 1080p projectors over 5000 ANSI lumens.

However, in addition to HD 1080p, there are several other very popular native resolutions for business and commercial applications. They include the following:

WUXGA (1920x1200) - WUXGA is a widescreen, 16:10 aspect ratio format that is highly popular in commercial and business use today. WUXGA projectors have the advantage of being able to natively display 1080p HD signals as well as 1920x1200 content. The price of WUXGA projectors has dropped dramatically, making it a go-to resolution for both business presentation and video applications. Here is a list of them:

WXGA (1280x800) - WXGA projectors have the same widescreen 16:10 aspect ratio as WUXGA projectors, but they are lower resolution and are therefore less expensive, all other things being equal. They are certainly good options when budgets are a key factor as in K-12 classrooms. However, the very bright 1280x800 models can be ideal in large scale digital signage applications where brightness is king, and the subject matter being displayed does not demand high resolution presentation.

XGA (1024x768) - XGA resolution has been around since the 1990's, but it is still a highly popular format that a lot of folks are buying. Why? Unlike WUXGA and WXGA just mentioned, XGA is a 4:3 aspect ratio, so it has the format of the older CRT-type TV picture rather than the modern widescreen formats. XGA resolution is inexpensive which contributes to its continuing popularity. Many models are well under $500. However, there are also many large venue XGA projectors on the market that are ideal for signage and other applications where widescreen format is not desirable or appropriate and higher resolution is not necessary. Think about the display of lyrics to guide the singing of hymns in a house of worship for example--the text is very large so high resolution is irrelevant. And many prefer buying into the 4:3 aspect ratio for this type of material rather than widescreen.

SVGA (800x600) - SVGA projectors are very low resolution, and like XGA they are 4:3 aspect ratio. Their major attraction is extremely low price, with many available for just a few hundred dollars. SVGA can be a good option for Powerpoint presentations or signage applications where there is no need to resolve much fine image detail.

4K (3840x2160+) - The latest ultra high resolution products are in the 4K family, which is at least four times the resolution of HD 1080p. For those who can afford them they are highly desirable in home theater. But they also have excellent application in the display of very high resolution graphics. If you've got the money and the need for super high definition images, buying into the new 4K projectors may be your ideal solution.

Which resolution is right for you?

The big issue here is how complex your subject matter is. If you are routinely presenting large financial spreadsheets or complex architectural schematics, you need at least HD 1080p, probably WUXGA, or if your budget can tolerate it, possibly even 4K. If you have a lot of video content you will also want HD 1080p or WUXGA to match the source material available in HD format.

On the other hand, if you're planning to use your projector for Powerpoint pic charts, bar graphs and general business presentation, you don't need to pay extra to buy into high resolution equipment. WXGA or XGA resolution projectors are perfectly adequate for this kind of work, and the best solution for the money.

If you plan to use your business projector in a dual purpose role for video at home, you'll want to go with HD 1080p or WUXGA business models that have particularly good video performance attributes.

Once you have determined which resolution most suits your needs, you can go to the Projector Database to find all projectors in that resolution class. The list might be lengthy at first, but this buying guide will help you narrow down the list to find the projectors most ideally suited to your situation.

I have two long throw Infocus projectors with a long through lenses. our screens are 110" and 53' ft distance in our church. We need to replace them with either new or used in our budget.Help

Ed, there's a lot more that goes into this decision than knowing screen size and throw distance. I suggest you get in touch with local integrator or contact one of our authorized resellers to talk you through it.

our community theatre has currently an IN 42 In-focus large venue projector, it is limited to 1080i fed by component. Would like an idea of a current projector with HDMI input and other modern input features. The projector struggles to provide sufficient light output for current use.It is throwing the picture about 20 metres and screen size is approximately 6.5 x 3.5 metres high. Do not know what the roll down screen ratio is. Has a relatively new light source in it. regards A.J.Chalinor
Rob Sabin, Editor Posted May 25, 2019 8:47 AM PST
Tony,your IN42 is rated for 3,500 lumens brightness with a new lamp, and according to our projection throw calculator it's not really even capable of an image of that size from that distance (about 65 feet?. So even if you're mistaken about the precise detail here it's obvious that the projector is woefully inadequate to the task...and that's without even knowing if you are using it with modest ambient light.

If you've shared truly accurate information about image size (rather than overall screen size) you would need a really large and bright (and expensive) projector to pull it off. I'm guessing though, that if you've been making due with your IN42 it's a much less demanding setup in reality and a step up projector in the 5,000-6000 lumen range will probably work for you. You really should bring in an A/V pro to assess it though to be sure.



I don't know what your budget is, but I would look through the scroll of the projector Road Tests that you'll find on our homepage and look for something rated for 5,000 lumens or higher range. You probably want at least WUXGA resolution at this point, which is basically 1080p. If you opt for spending on one of the less pricey laser projectors that have come out recently, you'll be able to justify the higher up front cost by avoiding the purchase of new lamps later -- you never have to replace the bulb in these units, which is usually several hundred dollars per replacement. Also, if the 5,000-6,000 lumens is adequate to the task and gives you some real punch, and you get at least WUXGA resolution, you may expand your possibilities of renting your space for entertainment or business presentations/events to help recoup costs. You've had a 3LCD projector all this time and I'd recommend you stick with that for a couple of technical reasons given your setup. The Epson 610U($3,500 street price) would probably work well if you could swing that. But there are others out there in this brightness/resolution category that use lamps if you're looking to save money up front, as well as projectors offering resolution similar to your IN42 (WXGA by today's widescreen standards, 1200 x 800 pixels) that would cost less. The main thing here is lumen output mated with a projector that can give you the image size you want from your established throw distance. Measure those things out carefully, select a couple of projectors to look at, then find them in our Throw Calculator to see if you can get the image you need at distance.

Very clear and concise article, thank you. Our projector will be wuxga 9900 ansi lumen, but the screen ratio (an outdoor building) is closer to 3x4 (portrait). Documentation states it is possible to use the projector on its side to get a vertical image. The conetent (video, images, graphics) has been created to fit the building (mapping) in files matching 1920x1200. There is alot of black space either side. This means a lot of the projected image will be effectively not used (the part falling off the building). This works on site but I was considering using the same projector but in a resolution that matches 4:3 such as xga, so that more of the pixel area of the chips are used. Will this effect quality of image and will it increase brightness as more of the projected light will fall on the building?

To clarify: Using a WUXGA projector in portrait, changing the ratio from 16:10 to 4:3 to project content which is 4:3

Or am I barking up the wrong tree?

Thanks AR
Rob Sabin, Editor Posted Nov 1, 2019 7:49 AM PST
AR, I'm afraid I don't know the answer to this, other than to suggest that if you give the projector an XGA res image the detail will be considerably hurt and the likelihood is that the projector will simply mask or turn off the unused pixels on the chip rather than scaling up to use them. Perhaps you should try some experiments to see how the projector behaves.
