iShopping.pk brings you the best Price for Dell PC 3D Ready Projector (1430X) With 1 Year Official Warranty and Free Shipping all over Pakistan.
The Dell 1430X is what you might think of as a basic DLP data projector, but a surprisingly capable one. It doesn't offer an HDMI port, which means you're limited to analog connections; its native resolution is 1024x768; and although it supports computer-based 3D at 720p, the 3D is best thought of as an ancillary feature. Dell doesn't include any 3D glasses with the projector, for example, and if you need more than a few pair, you'll wind up paying more for glasses than for the projector.
When it comes to the basics, however, the 1430X delivers top tier performance. In my tests, the autosync feature did well enough with an analog connection that a digital connection wouldn't have improved the image all. And I measured the projector as notably brighter than its 3200 lumen rating. Add in the excellent data image quality plus niceties like the 1.2x zoom, a low running cost, and fewer rainbow artifacts for data images than most DLP projectors, and the 1430X is a pretty impressive choice.
Excellent data image quality: The 1430X scored extremely well for data image quality. The autosync worked so well in my tests that the image was as rock solid as with a digital connection even on screens that tend to show pixel jitter with analog signals. In addition, both black on white and white on black text was crisp and highly readable at sizes as small as 7 points.
Colors in all preset modes were just a touch dark in terms of a hue-saturation-brightness color model, but they were also well saturated and suitably eye catching. Color balance was a little off in the brightest mode, with a slight greenish-yellow tinge in some shades of gray. However, most projectors have problems with color in their brightest modes, so that's par for the course. With all other presets, the various levels of gray were suitably neutral.
Few rainbow artifacts with data images: Rainbow artifacts are always a potential issue for DLP projectors. Most models, including the 1430X, tend to show them less often with data images than with video, but the 1430X does particularly well on this score. Not only did I see the artifacts far less often for data screens than with most DLP projectors, I had trouble making them appear even when I tried forcing them to show up by purposely shifting my gaze back and forth across the screen. It's highly unlikely that even those who are most sensitive to these artifacts will see them often enough with data screens to find them annoying.
Brighter than promised with wide brightness range: The measured brightness on most projectors is less than promised. The Dell 1430X stands out for being 10% brighter than its 3200 lumen rating, at a measured 3520 lumens in Bright mode on our tests. That makes it easily bright enough for the 98" diagonal image I used for testing, and even for larger images, to stand up to the ambient light in almost any conference room or classroom.
Good (not great) brightness uniformity: The 1430X score for brightness uniformity is a little low, at 70%, but good enough so it's not an issue. As a practical matter, it's enough variation so I could see the difference on a solid white screen, with the lower left corner noticeably brighter than the upper right corner. However, when you break up the image with text and graphics, the difference is little enough that few, if any, people will notice it. It's highly unlikely that anyone will find it objectionable.
Acceptable connectivity: With no HDMI port or other digital connection options, the 1430X's connectivity is best described as a step above minimal by today's standards, but not by much. Connectors for image sources include two VGA ports for computers or component video, plus one composite video and one S-video port. In addition, there's a pass-through monitor port, an RS-232 port for external control from a computer or third party controller, and a mini USB B port for wired remote control.
Arguably the most important limitation is for audio, with only one stereo miniplug input, so you can connect audio from only one source. There's also a stereo miniplug output for an external sound system, but with only one input, the only thing gained by connecting though the projector is the ability to adjust the volume from the projectors' controls.
