Why doesn't htc vr have a picture?

1. How to solve the problem of HTC Vive lighthouse bracket? I learned at the HTC Vive Summit that the HTC Vive Lighthouse has a special support. Even after searching for a long time in China, I still can't find an access channel, and I also found that other friends who use HTC Vive have encountered this problem. So I can only DIY one myself. According to the use requirements of the lighthouse, as long as it is fixed at a height of two meters, the laser emitting surface of the lighthouse should be about 0/20 degrees away from the wall/kloc, and the distance between the two lighthouses should not exceed 2. 5m。 HTC Vive originally came with a pair of small universal brackets that can fix the lighthouse on the wall, but considering the flexibility, it is better to choose a movable bracket. So, we removed the brackets of the two fill light lamps in the studio, and then fixed the attached small universal bracket on the fill light lamp bracket with adhesive tape to realize the universal adjustment of the lighthouse, and that's it (although it's a little ugly, make do with it. . . The effect is as follows). Of course, this is not the only way, as long as you can find a bracket about two meters high. It is also a good idea to choose a tripod with a fixed camera or DIY a pair of pipes yourself. Two. What happens when drawing a graphics card below 0 with GTX 9? Officially recommended, the lowest graphics card to run HTC Vive is GTX 9 paint 0. Since the adapted host hasn't arrived yet, let's try it with a computer with ordinary configuration for the time being. CPU, memory, etc. It basically meets the requirements, mainly because the graphics card is not good (the graphics card is NVIDIA GT Luer 0). Therefore, in the process of equipment inspection, although the handle and lighthouse are normal, the head display can't be recognized no matter how it is configured, and the indicator light of the head display keeps flashing red. Later, I found a game book with better configuration to test. The graphics card is GTX-50M. During the whole wiring process, everything went smoothly, and the head indicator light was in a green and normal state. After the platform starts, the head display is still unrecognizable. A screen in the head-mounted display can display the projected image of the host computer, but it still cannot be used. This is largely because the official only adapted GTX-9 graphics cards with 0 and above, and others. 3.20 Error Code 20 Error Code is a conventional HMD (Head-up Display) error message. The main reason for this error is: 1. The video card has not been updated to the latest driver version: 2. The graphics card is GTX9 drawing model below 0; There is a problem with the HDMI cable connection. In short, it is to prescribe the right medicine, check every mistake and solve it quickly. I wonder if my friends have ever encountered this kind of error code. This error occurred many times in the installation process. Later, according to the code error, it was found that it was an official USB driver problem in China. After the head display is connected to the host, the host will automatically install the USB driver of the head display. If the operation is improper, problems will occur: 1. The host USB port is damaged, and the solution is of course to try again with another USB port; Two. The network connection in China is not smooth. If the network in China is not good, the driver download may be interrupted. Please keep the China network open at this time. Three. Anti-virus software startup, etc. If the anti-virus software or driver wizard is started in the background during the automatic installation of USB drivers, the software may prevent the installation of drivers. At this time, it is best to close this kind of software before operation. Some problems encountered in use. "The head mounted monitor is enabled, but it is not located." This is likely to happen if HTC Vive is used in an environment with obvious reflective objects. The reason is that the lighthouse uses the principle of laser reflection to locate the head display and other equipment. If there are such reflective objects in the environment, such as mirrors, polished floors, glass ornaments, etc. , which may affect the normal work of HTC Vive. The solution is simple, that is, get rid of all the reflective things in the room or change rooms or go outdoors. At first, the room could not be used because of the glass wall and reflective floor. Later, the floor was covered with a yoga mat, and the glass was covered by the wall, so it returned to normal. ) 2. Please try to avoid shaking the lighthouse bracket. When you experience HTC Vive, even if all irrelevant things in the venue are removed, sometimes the game is too fierce and it is inevitable that you will encounter other things, so you need to pay special attention not to shake the lighthouse bracket. Because there are physical equipment such as motors in the lighthouse, if the lighthouse shakes too much during work, it may affect the normal positioning of the equipment and lead to misoperation of the application. Although the system itself has the function of "protective wall", in order to experience smoothly, it is best to take some avoidance measures, such as making the area a little farther from the lighthouse or making a protective fence when delineating the safe area. Three. The handle is not recognized. If you can't recognize the handle just after installing it, one reason may be that the handle is dead, which is reflected in the fact that the indicator light is red when the handle is started, so you can recharge it at this time. Another reason is that the firmware version of the handle is low. If there is such a problem when the system identifies the device, a prompt will appear. At this time, just connect the handle to the computer with a data cable, and then click the firmware update to solve the problem. However, there is such a problem. For example, a handle firmware is normal and a handle needs to be updated, but the system does not prompt which one it is, and the handle end does not display it accordingly. At this time, you can only try one by one. If you are prompted not to update after connecting to the host, it is another handle. Some unsolved problems how to make headphones and external speakers display sound at the same time? In order to improve the experience of users and onlookers at the same time, we hope that the partners who play and watch can hear the sound in the game at the same time, but we have no choice but to find a way to solve it, either headphones or speakers.
