10 Reasons For

Running Costs Are Very Low

The average running cost of the GT750ST is only £29 over 1 year based on average energy prices, which makes it one of the most economic to run 20000:1 contrast ratio data projectors that have been available for the last year.

Good Brand

20000:1 contrast ratio data projectors manufactured by Optoma have good reviews on average. We also checked the reviews for all data projectors (not just 20000:1 contrast ratio data projectors) and found that Optoma also has good reviews across its entire range.

Just Released Six Months Ago

This Optoma projector has only been on the market for six months.

Supports 3D

Like most of the other 20000:1 contrast ratio data projectors that have been on the market for the last year, the GT750ST supports 3D.

Chart Edit

Has a Built-In Speaker(s)

The GT750ST has a built-in speaker(s), as do most of the other 20000:1 contrast ratio data projectors that were launched around the same time as the GT750ST.

Chart Edit

1680 X 1050 (WSXGA+) Supported Graphics Resolutions

The GT750ST supports a maximum resolution of 1680 x 1050 (WSXGA+). That's 8% less resolution than the most frequently found supported graphics resolutions of 1600 x 1200 (UXGA). In addition, this data projector support supported graphics resolutionss of 640 x 480 (VGA), 800 x 600 (SVGA), 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 768 (WXGA), 1280 x 800 (WXGA), 1360 x 768 (WXGA) and 1400 x 1050 (SXGA+) and 1440 x 900 (WXGA+). The resolution of all projectors that have been around for a similar time to the GT750ST ranges from 640 x 350 (worst) to 4096 x 2160 (best).

Chart Edit

Quite Long Service Life of Lamp

Across all the projectors that came out in the last 12 months the service life of lamps range from 3,000h to 20,000h, and the average service life of lamp is 6,300h. At 20,000 hours, the GT750ST has a quite long service life of lamp compared to most of the other latest 20000:1 contrast ratio data projectors.

Chart Edit

Fairly Big Uniformity

At 88 percent, the GT750ST has a quite big uniformity compared to most of the other 20000:1 contrast ratio data projectors that were released in the last 12 months. The uniformitys of recently released data projectors range from 70% to 90%.

Chart Edit

Quite Quiet Noise Level

The quietest noise level of similar spec projectors that are a comparable age to the GT750ST is 22dB, the loudest is 35dB, and the average noise level is 31dB. With a noise level of only 22 decibels, the Optoma GT750ST has one of the quietest noise levels amongst data projectors of this age.

If you would consider a projector with a louder noise level then you might want to look at the DS348[pl_3381925_price] (29dB), or the DX349[pl_3434769_price] (29dB) both from Optoma.

8 Reasons Against

Does Not Support Full HD

The Optoma GT750ST does not support full HD. Most of the other recently released 20000:1 contrast ratio data projectors do support full HD.

We compared all the other projectors which also support full HD to this projector and we think the Optoma DS348[plb_3381925_price] is also worth considering.
