Change USB to VGA adapter, screen look dirty

[benjon]

I am using Vga audio set computer cable and connector in my computer. I buy this now Genietech VGA box and it will connect through component cables, do I need an adapter? because after that it looks screen dirty. actually the box has no direct component input, but only this video-in this is the adapter from this connector to components on the box. Can I have to buy separately? Please suggest.

It is because of bandwidth limitations of USB 2.0 connectivity are USB-connected monitors not for 3D applications. The CPU of the computer, the compressed video data sent over the USB bus and needed to be the obvious case of moving images much computing power. Computer games and other programs that require 3D graphics are not supported. If using several of these adapters, the demands considerable computing power of the computer. For standard video (not HD, a USB adapter for each computer monitor) at least computer with 1.6GHz Pentium M processor or single core 1.2 GHz class are necessary.

You need to check that the USB to VGA adapter consists of two parts. Without wires is not, because the VGA adapter requires extra energy and has a USB mini-B port. All knobs and LED indicator are also in the VGA adapter. The USB adapter draws power from the computer. Both parts have an external antenna for better reception. Transmitter and receiver must when playing 720p material (1,280 x 720 pixels) not more than five meters apart. The maximum range is according to the manufacturer up to ten meters. These ranges are also guaranteed only of sight. Likewise must be no frequency interference. The range is comparable with the Bluetooth standard. The maximum supported resolution is 1,600 x 1,200 pixels or 1,680 x 1,050 pixels.

Adding a second screen is now as easy as plugging in the vga adapter for multiple monitors. This USB graphics adapter I've already seen. They should also be limited by the performance. Power Point might have. I am using a ebay adapter but has a 24 +1 DVI - male. May be you missing the 4 analog pins. In the 24 pins, according to DVI-occupancy but only the digital signals. so you need to check it first and reply.

I have tested once with an old PC. The video card next to the VGA or DVI-I. From the DVI usually comes out a proper analog signal, if you stop taking a proper adapter with analog pins. That's what I wanted then a CRT monitor with a VGA port to connect to my surprise adapter. Except some flickering was not much. Second test was then with my new laptop with HDMI - DVI-D - adapter. And this miracle the adapter directly. The whole then back to the CRT monitor. was just as wrong. A computer of a real pure DVI-D output has not, unfortunately I have to test. In my opinion, the HDMI output to DVI adapter is equivalent.
