As a supplement to my review Epson PowerLite Home Cinema 2045 3LCD video projector, I conducted a series of tests to see how well it De-interlaces, processes and upscales video from standard definition sources.

The following video performance tests for Epson PowerLite Home Cinema 2045 Projector were conducted with an Oppo DV-980H DVD player. The DVD player was set for NTSC 480i resolution output and connected to the 2045 via the Composite Video and HDMI connection option so that test results reflected the video processing performance of the Epson 2045.

The test results are shown as measured by the Silicon Optix (IDT/Qualcomm) HQV DVD Benchmark Disc.

All tests were conducted using the Epson's 2045 factory default settings unless otherwise indicated.

Screenshots in this gallery were obtained using a Sony DSC-R1 Still Camera.

Shown in the above photo is a look at the first of several video performance tests I conducted on the Epson PowerLite Home Cinema 2045. This test is referred to as the Jaggies 1 test, and consists of a rotating bar that moves 360 degrees within a circle divided into segments. To pass this test, the rotating bar needs to be straight, or show minimal wrinkling, waviness, or jaggedness, as it passes red, yellow, and green zones of the circle.

This photo shows two close-up views of the rotating line in two positions. The lines are fairly smooth. This means that the Epson Home Cinema 2045 is performing the deinterlacing portion of the it's video processing takes successfully (at least so far), thus passing this test.

In this test, three bars are moving (bouncing) up and down in rapid motion. This is referred to as the Jaggies 2 test. In order for the Epson 2045 to pass this test, at least one of the bars needs to be straight. If two bars are straight that would be considered better, and if three bars were straight, the results would be considered excellent.

However, as you can see in this result, the top two lines look smooth, with just a hint of roughness on the third line. As seen in the above photo, this is definitely a passing result.

However, let's take a second, more close-up, look.

Here is the second look at the three bar Jaggies 2 test. As you can see in this closer example, shot at a different point in the bounce, the top two bars shows a hint roughness along the edges, and the bottom bar shows very slight roughness. However, since this is close-up view, this is still definitely considered a passing result.

For this test, the flag-waving action, the color combination of white stars on a blue background, as well as red and white stripes, provides a good video processing test.

As the flag waves, any of internal edges between the stripes, or the external edges of the flag become jagged, it means that the 480i/480p conversion and upscaling would be considered poor or below average. However, as you can see here, the outer edges and interior stripes of the flag are smooth.

The Epson PowerLite Home Cinema 2045 pass this portion of the test.

By proceeding to the following two photos in this gallery you will see the results with regards to the differing position of the flag as it waves.

Here is a second look at the flag test. If the flag is jagged, the 480i/480p conversion (deinterlacing) and upscaling it's considered below average. Just as in the previous example, the outer edges and interior stripes of the flag are smooth. Based on the two examples shown, the Epson 2045 passes this test.

Epson Home Cinema 2045 Projector - Video Performance - Race Car Test

Pictured on this page is one of the tests that shows how well the video processor of the Epson PowerLite Home Cinema 2045 is at detecting 3:2 source material. To pass this test, the projector is tasked to detect whether the source material is film based (24 frames per second) or video based (30 frames a second) and display the source material correctly on the screen, avoiding any unwanted artifacts.

In the case of the race car and grandstand shown above, if the 2045's video processing is not up to the task, the grandstand would display a moire pattern on the seats. However, if the video processing is good, the moire pattern will not be visible or only visible during the first five frames of the cut.

As shown in this photo, there is no moire pattern visible. This is a passing result.

To see how this image should look all the time, check out an example of this same test as performed by the video processor built into the Optoma GT1080 DLP Video Projector from a previous review used for comparison.

For another look at how this test should not look, check out an example of this same deinterlacing/upscaling test as performed by the video processor built into a Epson PowerLite Home Cinema 705HD LCD Projector, from a past product review.

The test shown in the above photo is designed to determine how well a video processor can detect and resolve the difference between video and film-based sources, such as video title overlays combined with a film-based source. This ability is important. When video titles (moving at 30 frames per second) are laid over film (which is moving at 24 frames per second), this can cause problems a video processor as the combination of these elements can result in artifacts that make the titles look jagged or broken.

As you can see in this photo example, the letters are smooth (any blurriness present in the image is due to the camera's shutter) and shows that the Epson PowerLite Home Cinema 2045 can display a stable scrolling title image.

The image shown in this test has been recorded in 1080i (on Blu-ray), which the Epson PowerLite Home Cinema 2045 needs to reprocess as 1080p. To perform this test, the Blu-ray Test Disc as inserted into an OPPO BDP-103 Blu-ray Disc Player that was set for 1080i output and connected directly to the 2045 via HDMI connection.

This test detects the ability of video processor of the Epson 2045 to be able to distinguish between the still and moving parts of the image, and also display the test image in 1080p without flickering or motion artifacts. If the projector is going its job properly, the moving bar will be smooth and the lines in the still part of the image will be visible at all times.

To make the test more difficult, the squares on each corner contain white lines on odd frames and black lines on even frames. If the still lines in squares are visible, the processor is doing a complete job at reproducing all of the resolution of the original image. However, if the square​s are solid, and are seen to vibrate or strobe alternately in black (see example) and white (see example), then the projector is not processing the full resolution of the entire image.

As you can see in the photo shown above, the squares in the corners all display still lines. This means that these squares are being displayed properly as they are not showing a solid white or black square, but a square filled with alternating lines. In addition, the rotating bar is also very smooth.

The results indicate that Epson PowerLite Home Cinema 2045 does well at deinterlacing 1080i to 1080p with regards to both still backgrounds and moving objects, even when in the same frame or cut.

Here is a close-up look at the rotating bar in the test as discussed in the previous page. The image has been recorded in 1080i, which the Epson PowerLite Home Cinema 2045 needs to reprocess as 1080p, and the rotating bar should be smooth.

As you can see in this close-up photo, the rotating bar is smooth, which indicates a passing result.

Additional Test Results and Final Notes

Here is a summary of the additional tests performed:

Color Bars: PASS

Detail (resolution enhancement): PASS (However, soft from composite video input source that from an HDMI input source - both using 480i input resolution).

Noise Reduction: FAIL (Default Setting), PASS (Noise Reduction Engaged)

Mosquito Noise (the "buzzing" that can appear around objects): FAIL (Default Setting), PASS (Noise Reduction Engaged)

Motion Adaptive Noise Reduction (noise and ghosting that can follow rapidly moving objects): - FAIL (Default Setting), PASS (Noise Reduction Engaged).

Assorted Cadences:

2:2 - FAIL

2:2:2:4 - FAIL

2:3:3:2 - FAIL

3:2:3:2:2 - FAIL

5:5 - FAIL

6:4 - FAIL

8:7 - FAIL

3:2 (Progressive Scan) - PASS

Based on the tests that were conducted, the Epson PowerLite Home Cinema 2045 does a good job with most video processing tasks but does not do well with video cadence detection, and out of the box default noise reduction, which is typical of the Epson projectors I have reviewed to date.

My suggestion, don't depend on the out-of-the-box default video processing settings to provide the best result with analog, lower resolution, or interlaced video sources (such as VCRs, DVD players, cable boxes, or game consoles without HDMI connections). Definitely take advantage of the additional video processing settings that Epson provides with this projector when viewing non-HD sources.

As a further note, I noticed that when Epson's "Image Processing" function was set to "Fast", images tend to vibrate, whereas when set to "Fine" there was more, overall, image stability, and smoother motion.

In addition, to evaluate 3D viewing performance, I played the 3D tests provided on the Spears and Munsil HD Benchmark 3D Disc 2nd Edition and the Epson 2045 passed the basic depth and crosstalk tests (based on visual observation), although I did detect some occasional, very subtle, flickering, as well as a slight brightness drop, as a result of using Active Shutter glasses, but overall, the 2045 provides a good 3D viewing experience.
