First, you need to confirm whether the VGA cable is normal or whether it is connected normally.
Then follow the steps below"
1.Please make sure that the output resolution of your laptop is set to the true resolution supported by the projector (1024*768 is the best), and the refresh rate is set to 60Hz;
2.Again, please right-click on the blank space of the notebook desktop and select "Properties" -> Settings -> Advanced -> Troubleshooting" = > "Hardware Accelerator" and drag it to the "None" state (the default is "All"), click OK;
3.Finally, you only need to press the function combination key of the laptop keyboard to switch, generally the FN+F key (the key combination of different brands of notebooks is different, generally a key in F1 F12, with icons similar to two monitors on it).
4. If none of the above methods can solve the problem, it is not ruled out that there is a compatibility problem between the projector and the notebook, you can try to update the graphics driver of the notebook, or connect the projector to a desktop computer, set it to use it at the same resolution and refresh rate, and confirm whether there is an image output, so as to confirm whether the projector itself functions normally.

Depends on the size of the room, the number of people, and then choose the brightness, the distance of the projector, if the number of people does not exceed 3000 lumens almost, depending on your specific situation, I have qq information.

There are two scenarios: one is hardware failure; The second is software settings. Two solutions: one is to leave it to others to deal with, such as calling Sony service**, WeChat***, etc.; The second is to deal with it yourself.
The likelihood of something going wrong with the hardware shouldn't be very high. Consider whether you've recently used an external microphone to record and the software settings haven't been adjusted, or if the audio function has been muted. It is also possible that the sound was recorded, but it is not possible, you can copy the recorded file to the computer for analysis.
If you haven't used an external microphone before, you can consider connecting an external one, find a random headphone with an inline control, and try it with an adapter.

Hello landlord.
The Sony has a sleek and fresh look, with a lot of periscope lenses, touchscreens, and colors to choose from, using German Carl Zeiss lenses. Sony's T-series is sleek and innovative, with a larger touch screen and colors that outshine consumers, especially female consumers. Sony's W series is based on the T series, using telescopic lenses and non-touch LCD screens.
Sony's W series is a mid-to-high-end practical consumer household model series, which mainly uses good imaging hardware and software, while the T series is mainly not very strong in appearance; Sony's H-series are quasi-professional non-SLR telephoto digital cameras; The Sony S series is a low-end digital camera series for home use. If you want to buy a camera with a periscope lens, Sony's T series has the most models; If you want to compare it with cost performance, you should choose the W card digital camera series.

Sony's cards are MS cards (memory sticks), memory sticks, which are memory hardware developed by Sony itself, which can be used on almost all products in his own home, including cameras, camcorders, PSPs, computers, etc.
In the case of Canon cameras, the SD card used to be more popular, and it was jointly developed by some companies such as Panasonic and Toshiba.
In fact, it can be seen that these companies are competitors, and the two cards are not the same model, of course, they can't be mixed.
It's like the bullets of the AK47 and the M4 carbine are not interoperable.
-
Sony has a dedicated one, what is it called.
There are also those that support SD cards at the same time.
-
Not necessarily, Sony is generally dedicated to itself and is cheaper.
-
Absolutely not! Sony digital camera memory cards use Sony's dedicated storage device, memory stick memory
Stick, Canon's use an SD card, and these two devices are not universal.

Sony's digital camera has E62:20, which is a hardware failure of the anti-shaker, and you need to contact the after-sales service for disassembly detection;
The first to introduce the concept of image stabilization was Nikon Corporation of Japan, which introduced a pocket camera with vibration reduction (VR) technology in 1994.
The following year, Japan's Canon launched the world's first lens with an image stabilizer, the EOS 75 300mm F4 IS, where IS is the abbreviation of Image Stabilization System, which is customarily referred to as the "image stabilization system".
There are three main types of image stabilization: optical image stabilization, electronic image stabilization, and photoreceptor protection (CCD).

After connecting to the computer, turning on the Sony camera will prompt you to select the memory, if you don't choose it, of course, it is not reflected on the computer, it is recommended that it is better to use a card reader, which is more convenient, and the speed is faster than reading directly on the camera.
-
Obviously, the hardware is a problem, and it is repaired to find the local Sony after-sales service.
-
Remove the battery directly, remove the battery and install it again, and try to restore the factory settings if it is not good.
-
If you have a problem, first go to your local Sony customer service repair station. Get the right medicine.
If it's only Sony's***, then choose EX500, if it's another brand's ***, choose Senhai, CX400 has good sound quality, adapts to almost any machine, EX700 I despise, not to mention EX500, of course, if it's with Sony's own front end, the first choice is EX500
Both machines belong to the classic model.
The key to buying a camera is to look at the size of the CCD, which is the same for both machines. >>>More
