I caught one of the first five pieces to use with a PC for monitor cloning and I don't regret the purchase, it's a hilarious projector in a low price range. The first thing I'd highlight is the excellent autofocus and tilt correction, they work really well, which is really handy if you'll be moving and rotating the projector a lot, just press the button on the remote and the image will calibrate. Auto calibration is also performed every time the projector is started (can be turned off) and there is a manual setting for fine-tuning the sharpness and keystone adjustment, so if you want to place the projector on a fixed position (ceiling, tripod), you can turn off auto focus and tilt correction after the ideal setting. The projection itself looks good and the image can be widely customised, from brightness, contrast, colour temperature, tint to sharpness and gamma, or choose from preset profiles (movie, sports, etc. ). I'd like to point out that at the official launch of the T1 Pro in the Philippines, there was a nice 700 ANSI lumens luminance figure (mistake or intention? See. photo), which is of course a lie, the projector handles 220 ANSI lumens, sufficient for darkened rooms, and for myself I can say that the image is clearly visible on a dark grey wall even with several ambient lights on in the room. The manufacturer also states 60W power consumption, but the official documentation states 75W power consumption, however, the actual measurement showed a power consumption between 50-60W, which is in the standard, but well, they have a mess in it. As far as cooling noise is concerned, I am very satisfied, the Yaber T1 Pro is much quieter than the competing Helmer SP 600, and is almost on par with the Xiaomi L1 Pro. The sound from the small speaker, cleverly placed in the stand, won't offend or delight, it will be enough for some projection at the cottage, but an external soundbar or bluetooth speaker will make the experience much better. Linux as an operating system compared to Android TV I initially perceived as a disadvantage due to the limited number of applications, on the other hand, the operation of the system is very smooth, without glitches, with immediate response to anything and in the end, for my way of using it with a PC, it is ideal, however, it is possible to connect a dongle/stick with Android TV as with the Yaber T2, if you can not do without it. In conclusion, at the introductory price of 3990 CZK it was a great buy and I can recommend it even at the current price of 4390 CZK, which is still better than buying directly from Yaber for 4579 CZK. If you want a decent projector for nighttime projection at a low price, go for it.
