How To Adjust Epson Projector Screen Size

[Mireille Kreines]

Manualadjustment should require only a few steps. Having a physical adjustment button or slider on the projector keeps you from having to go into the menu to change your settings. Automatic adjustment is an even greater benefit, allowing instant alignment with no need for user control of any kind. Most projectors have some degree of adjustability, but some are more advanced than others. Here are some methods of positioning your projected image:

When a projector is not centered directly in front of the screen but tilted or angled toward it, the resulting image will be distorted into a trapezoidal shape. However, keystone correction will correct this so the picture will be perfectly rectangular. This can be done manually or automatically.

With automatic keystone correction, the projector will automatically detect and correct the distorted image, with the touch of a button. A vertical keystone correction aligns the distortion on the top or bottom of the image, and a horizontal keystone correction aligns the distortion on the left or right side.

Lens shift allows the lens to move vertically and/or horizontally within the projector to provide a perfect, straight-edged image with uniform focus. This allows for more flexible installation and placement options for the projector, with no loss of resolution. A vertical lens shift allows the projector to move the image up and down, and a horizontal lens shift allows a lens to move from side to side.

Like keystone correction, lens shift corrects the distortion of the image. However, lens shift has no loss in the quality of the image, since there is a physical movement of the lens to account for the adjustment rather than an alteration of the image itself for the correction.

Optical zoom is a function of the lens allowing you to increase the image optically without distortion or loss of image quality, while digital zoom, which simulates optical zoom, is a function of the projector allowing you to enlarge a portion of an image.

Some projectors have lenses that can be changed. if a projector allows for optional lenses, you have greater flexibility on where you can position the projector in relation to the screen. Lens options allow users to choose the motorized lens most suited for their environment, and a quick-release lever allows for easy lens exchange. Using optional lenses, projectors can handle projection distances near and far.

Looks like Kevin has you covered, but yes the zoom is more for fine adjustment to get the projected image to match the screen how you like it. Each projector has a throw distance range that it will need to be mounted within that range based on the desired screen size.

You have two ways to correct the problem of the projected image not filling your screen. You can either zoom in with the projector to make the displayed picture larger or you can move where you mounted the device further from the screen. Obviously using the zoom feature will be a much easier solution.

If the image on your screen is slanted it means the projector or screen isn't level left to right. This is caused by the roll of the projector being skewed. To adjust this, make sure your projector is level.

If the projector is leveled to the screen and the pitch is accurate, but one side is shorter than the other, then the issue is the yaw of the image. To correct this the projector would have to be turned to the right or left until the corner comes in line going too far would shrink the other side. This will make the edges squared off.

Some projectors have the ability to shift the image into a specific position using lens shift. To do this make the image squared off using the corrections above then lens shift the image into position and zoom in to fill your screen.

Projectors that have lens shift enable you to have flexible placement without needing to be perfectly aligned vertically or horizontally. This can eliminate some of the challenges you would face with the pitch, roll and yaw of the projector.

In giving presentations from my MacBook Pro on an Epson Data Projector (VGA connection), there is I have invariably found a decrease in the display dimensions. Initially only part of the previous screen area shows, but can be reset to fill the smaller screen.

Failing all else I could record and show a movie or temporarily change the stylesheet, but my question is whether there is any way of changing the resolution of the data projector display from my Mac.

Your projector probably has a maximum native resolution of XGA or 1024x768 (standard iPads have a resolution of 1024x768 points). Some projectors will allow you to send a higher resolution signal and scale it down for you. Most projectors I have seen don't do a great job, but it at least functions. To see if your projector will do that:

The other option is to purchase a VGA scaler (For example, the Kramer VP-426 takes VGA input and then outputs VGA). You need hardware that will take one of the various formats your Mac can output and output at XGA (1024x768). What the hardware will do is let your Mac output a higher resolution, forcing the web page to render the "desktop" size, but output it to the smaller resolution projector. But honestly, purchasing a scaler for this purpose is overkill.

To get the most out of the quality components used in the LS11000, it is also equipped with a new video processor called the ZX Picture Processor. This is Epson's most advanced video processor. It handles real-time color and contrast adjustment, HDR tone mapping, frame interpolation, and resolution enhancement to ensure source material is reproduced as the content creator intended.

While the metadata in HDR10 content is static, in HDR10+ and Dolby Vision content, this metadata is dynamic. Since the luminance information for each scene is embedded into the content as dynamic metadata, tone mapping can be optimized scene by scene or frame by frame. This helps the projector faithfully reproduce the HDR images as intended by the creators.

HDR content is currently distributed mainly in HDR10 and/or Dolby Vision, but Amazon Prime Video has announced support for HDR10+. There is also a limited number of 4K UHD Blu-ray discs available, and a select number of UHD BD players from companies like Panasonic support it.

The LS11000 is equipped with a blue laser phosphor light engine. Epson says the laser light source in the LS11000 has a rated life of 20,000 hours at full power. This means owners can enjoy several years of nearly maintenance-free operation.

While brightness is important, it is deep blacks and high contrast that separates a premium home theater projector from a standard unit. Epson claims that when laser dimming is enabled, the LS11000 has a dynamic contrast ratio of 1,200,000:1.

While the additional features and enhanced performance found on the LS12000 justify its $1000 price premium, for many customers, the less expensive LS11000 might be a better fit. For example, someone placing the unit on a shelf projecting onto a 16x9 screen in a room with some ambient light. The Home Cinema LS11000 is arguably the best home theater projector priced below $4000.

Except for color, the chassis of the white Home Cinema LS11000 looks nearly identical to the black Pro Cinema LS12000. So, if you read our review of the LS12000, you will notice that a lot of the information on this Hardware page is similar.

The LS11000 is larger than most single-chip DLP projectors but is it is more compact than most native 4K projectors. The LS11000 is approximately 20.5 inches wide x 21.9 inches deep x 16 inches high and weighs about 28 pounds.

The top of the projector has status lights. On the left side of the chassis, there is an air intake vent. On the right side of the chassis, along with the power and input buttons, there is another air intake vent covered by an air filter.

There is a pair of HDMI 2.1 (HDCP 2.3) inputs. Both HDMI inputs are 48Gbps, supporting 4K HDR up to 120fps. We should note that while the inputs can support up to 48Gbps, the HDMI inputs/outputs found on most A/V Receivers, video switchers, and gaming consoles are limited to 40Gbps.

There is a USB-A input with 5 Volt- 2.0A, which is enough output to power/charge a streaming media player. The second USB connection is a 300mA power port designed to power an active copper or optical HDMI cable.

The LS11000 does not dynamically tone map HDR content. However, you can quickly access the HDR adjustment settings via a dedicated button. This makes it easy to fine-tune the HDR tone mapping based on the movie/scene.

The menu images shown in this section represent only a small number of all the sub-menus available. I tried to show a couple more notable sections found in the sub-menus (image, setting, networking, etc.).

The menu system of the LS11000 is well organized and easy to navigate. There are a lot of settings on multiple pages, so I like that many of the picture adjustments can be directly accessed via discrete buttons on the remote control.

Like the Pro Cinema LS12000, I reviewed previously, the picture quality of the Home Cinema LS11000 was very good out-of-the-box. In fact, the color reproduction of the LS12000 and the LS11000 looked and measured similarly. There are five different preset SDR picture modes available, I found the NATURAL mode was the most accurate.
