A very professional question! D SUB to DVI

See if your monitor's interface is DVI-D or DVI-I. If it's DVI-D, you can't transfer it, if it's DVI-i, you just need to use a line with D-Sub to DVI to transfer.

The difference between DVI-D and DVI-I: Look at the largest needle on the side of the connector if there are four small holes around it. If there is, it is DVI-i, that is, it can be transferred.

Your laptop can't be connected to a display device with a DVI digital interface because it doesn't have a DVI digital interface.

This is because a digital signal can be downgraded to an analog signal by a conversion head, but an analog signal cannot be upgraded to a digital signal by a conversion head.

So, your request cannot be fulfilled.

Turn down the resolution of the apple of 23, I don't know if it's okay?

The Apple display only has a DVI port - try it with the D-Sub to DVI adapter, if it doesn't work, there is really no way.

If the notebook is older and the video memory is too small, it really doesn't support such a high resolution,I remember that the ATI Rage graphics card I used with 4M video memory can only support 800x600 resolution,If it's an integrated graphics card, make the video memory bigger,If you're using a relatively new notebook,It may be a problem with the adapter,Change a famous brand,For example, the quality of the D-Sub to DVI connector of the brand "Akihabara" is very good, I bought it for my friend.

The physical limit of the VGA line must be set at 1600 1200, and after this standard, the DVI line must be used to ensure that the transmission of images will not be interrupted and interfered with.

1 Reduce the resolution Using an adapter.

2 Use a laptop with DVI output.

Haven't seen that much support? /...Don't know if there's a patch

Comparison of the use of D-Sub and DVI-D.

The edges of the images and text output by the DVI interface are extremely clear, and the picture quality is sharp and delicate. The images and text output by the D-Sub interface are slightly soft, and the edges are not sharp enough.

Although the images and text displayed on an LCD with a D-Sub interface are not as sharp as those with a DVI interface, they are definitely better than most flat screen displays. This is all due to the superiority of liquid crystal technology. Here is another benefit of the DVI interface.

When using the D-Sub connector, you can see that there is an Auto option in the adjustment menu, which is used to automatically adjust the LCD to the optimal setting. When connected with the DVI port, the LCD will automatically adjust the screen after booting, and the user does not need to operate again, which is greatly convenient to use.

There is an Auto option in the OSD menu when using the D-Sub interface When using the DVI interface, there is no Auto option in the OSD menu.

But LCD displays with DVI interfaces are not perfect either. When the LCD uses the DVI interface as the image input source, there will be more or less "ash loss" problem. "Ash loss" means that the LCD display with DVI interface is a little worse than the D-Sub interface in grayscale display.

It is recognized that in DVI mode, the gray scale can only support up to 256bit, and the D-Sub mode can be higher than 256Bit, so the DVI mode of the LCD monitor will have some "ash loss" phenomenon compared with the D-Sub mode.

It can be seen that in the grayscale display, the effect of D-sub mode is better. In actual use, the phenomenon of "gray loss" is too serious, which will affect the picture effect, especially in the scene where the image is relatively dark. Therefore, when you buy an LCD monitor, you should pay attention to the problem of gray scale.

Generally speaking, if the phenomenon of "ash loss" does not affect the use, it is acceptable.

You turn it the other way around, and it won't work. If the graphics card does not have a DVI or HDMI interface, then you can only change the graphics card or the monitor.
