Optoma PT105 Gaming Projector Review

Marc Davidson, December 15, 2011


Although the Optoma PT105's price, technology, and resolution make pocket projectors the most appropriate point of comparison, that's only because there's nothing else quite like it. It's not even close to a pocket projector in size, and there are some important differences in functionality. It's much easier to set up, for example, thanks in part to its use of standard connectors instead of proprietary connectors and separate adaptors.

Much of the PT105's advantage in image quality comes from its lens. In fact, the lens is not only higher quality than any lens on a pocket projector, it is easier to focus, mostly because the larger case has room for a more easily controllable focus wheel.

Compared to more mainstream projectors, the PT105 offers low brightness and low resolution, but it also offers a much lower price. More importantly, the brightness and resolution are good enough for the intended purpose and a good value for the price. If you want a very inexpensive projector you can setup quickly for a game playing session the Optoma PT105 is a more than attractive possibility.

I bought one. Found it to be very good, exactly like the review said, down to the T.

The only problem? It died before I even reach the 10 hours mark. Sent it back to the service center, it worked like a charm. Brought it back home, it refused to power up. But once in a while, it will work. I tried different power sources, different connectors, even different locations, and if I get lucky and it is in a good mood, it will work. On most days, it just likes to play dead.

Optoma is one of the leading projector manufacturer in the world, so I have no idea what is happening. Maybe my unit is defective, but how can you convince the service center that your unit is defective when it worked perfectly while at the service center?

I know $199 is not a lot of money for a projector, but it is a lot of money for a paper weight that some times work as a projector.

The problem turned out to be a faulty power adapter. I found that out with the help of a friend. Bought a replacement at a local electrical shop. Everything works fine.

Also, Optoma doesn't seem to like responding to customer e-mails. It's like, my problem is not a problem and their defective product does not warrant any attention.

So, guess who will never buy another Optoma projector ever again? I'll also not recommend anyone to buy anything from a company that doesn't care about their customer or their own defective products.

The picture is beautiful for the price (HDMI), but frankly, this model's focus wheel seems to have a slight flaw that makes your image continuously go out of focus. From the comments I've seen across the interwebs, the complaints are similar: no matter how finely you adjust the wheel, your image will become slightly blurry (enough to distract from your experience) after roughly 20-45 minutes. Additionally, some users note that half of your image appears slightly sharper than the other half, no matter your adjustments. Regarding the focus wheel, I know of no trick/hack to correct this problem. I've opened my projector, taken the wheel out/apart, cleaned it, tightened screws, and have even tried to modify the interior of the case with something to either "catch" the lens or make it sticky to prevent slippage. I've even tried the simple solution of putting duct tape over the wheel after setting it. All to no avail! Simply put, if you plan to use it for anything exceeding 30 minutes, expect to get up from your chair and adjust the wheel. Kid-friendly, adult-irritating.
