Epson PowerLite 1751/1761W: Compact, Light-weight Projector for Traveling Professionals


Epson PowerLite 1751 3LCD Projector:

Epson PowerLite 1751 is an affordable 3LCD projector for offices/traveling professionals. It’s compact, light-weight and sleek. There maybe projectors that are smaller than this model, but if a projector is too compact it might get heated up faster and that might reduce its reliability. A dual-purpose projector like this can be used at offices and can be carried around. The Epson PowerLite 1751 3LCD projector also comes at an impressive price, considering the features it offers and the popularity of Epson in the projector market.

Highlights/Notes

  • Brightness: 2600 Pixels. Epson has the same white & color brightness levels. Frankly, 2600 Lumens is a lot of brightness! It is even possible to use this projector in a large auditorium (with lights switched off). In board rooms/conference rooms you can use it comfortably with lights switched on.
  • Resolution: XGA (1024 x 768). Resolution is a very important parameter in choosing a projector. Higher the resolution, better the images/text. XGA should be sufficient for normal applications. That said, if you have a higher budget, it maybe better to buy a WXGA projector. Higher resolution will make a projector future proof. With the falling prices of projectors, you’ll most probably be changing the projector in a few years (instead of changing the lamp, etc.). Hence, it is fine if you deliberately want to invest less (in this model), as it should be sufficient for most applications today.
  • Technology: 3LCD (3 chip). Between LCD and DLP projectors, LCD projectors have a better color reproduction capability. The images look brighter and the colors look vivid, natural and beautiful. DLP projectors can give a sharper image (good for reading small text). But since the image is going to be projected on a large screen anyway, LCD projectors might be a better option for corporate/business presentations.
  • Lamp/Lamp-life: 230W Lamp, 4000 Hours of lamp life (in normal mode). Lamp life is an important consideration because lamp is a consumable and you need to change it after its life-time. Most manufacturers do not give a warranty/give a limited warranty on lamps. Also, the brightness of any projector lamp decreases with increasing usage. 4000 hours maybe more than sufficient for most business applications for a few years.
  • Screen Size/Distance from the screen: 30″ – 300″ / (2.4′ – 28.8′). Should be sufficient for most applications. It has a decent throw ratio.
  • Keystone correction: When you keep the projector on your table and project it on a screen that is above the table-level, you get a trapezoidal image on the screen. While this projector automatically corrects the vertical keystone correction, there is a manual horizontal keystone correction, as well. Try not to use the horizontal keystone correction as far as possible (it can break the image/text). Try to place the projector straight to the screen, instead.
  • USB Plug n Play: Instead of connecting the bulky VGA cable, you can just connect the USB cable and start projecting (video). The only issue with this feature is, there are so many other devices that require a USB port at any point of time! It is better to take both the VGA cables (which are not that bulky) and the USB cable for your presentations. This feature is available for Mac & PC.
  • PC free presentations: Even though some projectors like this may support PC free presentations, they have some limitations like the file formats supported, limited functionality, etc. Try to use your laptop or a PC available in the venue as much as possible.
  • Contrast ratio: 2000:1. While some DLP projectors claim a higher contrast ratio, be aware that contrast is measured differently in LCD and DLP. Color reproduction is always better in LCD projectors.
  • Focus/Zoom: Manual Focus, Manual Zoom (1:1.2). Don’t go with auto-focus models. Manual focus is important for the best clarity.
  • HDMI Input: Yes. HDMI is a good option if you want to play HD videos. HDMI cables can carry both audio and video in the same cable.
  • Speaker: 1W. Though there is an in-built speaker in most business projectors, they are almost there as a formality. Do not use it unless it’s an emergency and you don’t have any speakers to connect to, in the venue. Alternatively, consider buying a decent laptop (external) speaker.
  • Heat/Noise: Every projector makes some noise and generates heat. It is for this purpose that they are ceiling mounted. But the noise level of this projector is lower than most others in the market.
  • Security: Kensington Lock. You can physically lock this projector, if you want to! It’s an excellent option for traveling professionals. Kensington lock slots are also available in many laptops. You must use these things if you travel frequently.
  • Instant Off: If you accidentally shut your projector, the fans will still run for sometime to cool the lamp (in this projector). Generally, try to keep the main power on (for a couple of minutes) after you switch off the projector. It cools the lamp and hence increases the durability of the lamp.
  • Dimensions/weight: 11.5″ x 8.3″ x 1.7″ (W x D x H)/ 3.7 Pounds. It’s a boon for mobile workforce!
  • Warranty: 2-year warranty for the projector and 90 day warranty for the lamp. I hope you noticed the lamp-warranty part. Normally lamps from good brands like Epson don’t fail, but you need to be ready to replace it if it fails anytime after 90 days. Just budget an eventuality cost (hopefully you won’t ever incur this cost before the 4000 hour lamp-life).

Epson PowerLite 1761W 3LCD Projector:

For a small additional cost, you get excellent value with the Epson PowerLite 1761W 3LCD projector. The features/specifications of this projector are similar to the Epson PowerLite 1751 projector, except three important differences –

  1. Native WXGA (1280 x 800) resolution: Of course, the projector is backward compatible with lower resolutions (without any loss in image quality) and it is also forward compatible with higher resolutions (but there maybe a small loss in image quality). Higher resolution is very important in projectors, especially as the native resolution for monitors/laptops keep increasing frequently.
  2. Wireless Connection with PC/Laptop: Wireless connectivity for projectors (with PC/laptop) is a great idea because you don’t have to go near the cable & connect the projector to make presentations/change slides. You can just present from where ever you are, within the room. Wi-Fi has a decent range (over 100 feet). There are some limitations to projecting wirelessly (like you may have to install a software beforehand and you may not be able to present certain media forms like video, etc.), but it is a nice feature to have, especially in a business projector. The built-in wi-fi adapter is 802.11 b/g/n compatible.
  3. Aspect ratio: 16:10 (Natively supports both 4:3 and 16:9 modes). This projector is great if you want to show videos/watch movies as it natively supports the 16:9 aspect ratio, which is common for videos. Especially, HD videos.

I suggest you to buy the 1761W projector over the 1751 projector, considering the small cost difference between them.

Buy from: If you live in the United States (US), you could buy this projector from Amazon.

1. Epson 80-inch dual aspect ratio tripod projector screen (16:9, 4:3).

2. Epson universal projector ceiling mount.
