Given that Optoma's GameTime projectors already focus on games, you might wonder why the company needs a separate line of PlayTime projectors, like the Optoma PT105. The answer is that Optoma's GameTime projectors are for serious gamers, while the PT105 is for more casual use. In case you have any doubts, the projector is packed in a box that's decorated with a photo of two young children, with one holding a video game controller.

Don't misread this to mean that the PT105 is a toy. To the contrary, it's pretty impressive for the $199 street price. However, it's important to judge it in the right context.

The PT105 is basically a pocket projector in a much bigger case. It's built around a DLP chip paired with an LED light source, just like most pocket projectors, and Optoma rates it at 75 lumens. That makes it brighter than many pocket projectors, but not as bright as some. Its connection options are limited by most projector standards, but generous for a pocket projector. Finally, the native resolution is low for what you might think of as mainstream models, but typical for a pocket projector, at 854 x 480.

Despite all of these similarities to pocket projectors, the PT105 offers a solid step up in image quality thanks to it's being big enough for a better lens than can fit in a pocket projector's tight dimensions. All this makes the PT105 an intriguing and inexpensive option for game playing, and to a lesser extent watching movies.

Strong Points

Good data image quality. Odds are you won't be tempted to use the PT105 for business, but only because the PlayTime logo might look unprofessional. Even so, data image quality still matters. And the simple truth is that the projector does better with data image quality than any number of pocket projectors meant for business.

Keep in mind that games are visually a cross between data and video. Like data images, they include screens that demand fully saturated, eye-catching color and readable text. Like video, they include subtle gradations and movement. That means good image quality for games requires good quality for data and video too.

In our data tests, colors qualified as both bright and well saturated in terms of a hue-saturation-brightness color model. In addition, fine detail was suitably crisp for the resolution, and color text on color backgrounds was easy to read even in an assortment of color combinations, an issue that's particularly relevant for games.

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.
