Which exactly is the problem between the graphics card DVI and the display DVI

Quite simply, DVI can transmit analog signals and digital signals, and VGA can only transmit analog signals.

Your monitor's DVI only receives digital signals, (because it provides a VGA analog signal input interface, so it is not necessary for DVI to also support analog signals).

And your graphics card,It's not a good one.,His DVI only provides analog signals (just simply convert the analog signal VGA interface to DVI interface,Simply put, it's equivalent to a 5 yuan to buy a DVI connector on the VGA)

So you find out that VGA, no problem, there is a problem with DVI.

Note: (Of course, it is also possible that your graphics card is fine, and the DVI output also outputs digital signals, but the DVI interface of the display only receives analog signals) To put it bluntly, the display or graphics card has a compatibility that is not very good.

Do you take a DVI speaking exam? That card of your Sapphire should be two DVDi, right? Change the port,Change it in the shutdown state,Turn it on again after changing,If both ports are connected to this monitor, the display is not lit, and the other is on, that is, your monitor is not good

Also, they are tested with a line, so that it can be proved that it is not a problem with the signal line.

Also, is it that the bright display you replaced is large, such as 22 inches, and the small one that you are not bright, such as 19 inches

In that case, you have turned up the resolution of the system, which exceeds the display resolution of the 19-inch monitor, and the image cannot be output.

And the other colorful machine you use has a low resolution, so the 19-inch one can be displayed!!

Try it, that's all I thought of first!!

DVI-D graphics cards transmit pure digital signals, and the DVI interfaces on general LCD monitors belong to the DVI-D standard.

In addition to transmitting digital signals, DVI-I also has 4 separate signal lines to transmit analog signals, and the DVI-I interface can be compatible with ordinary VGA interfaces through a simple converter, using traditional CRT displays. DVI-I is an analog technology that modifies circuits, not true DVI.

Therefore, in theory, the DVI-D displays a clearer image than the DVI-I.

There are several DVI interfaces, some are mixed transmission of digital and analog signals, and some are pure digital signal transmission. The VGA interface can only transmit analog signals.

If you can't adjust the best resolution from DVI to VGA, you can buy a VGA to HDMI adapter to solve the problem.

Your monitor only has a VGA port,I'm sorry to tell you,It's best to change the monitor,It's not that you can't change the resolution,It's that if you use the VGA interface of the display, it's easy to produce water ripples and hurt your eyesight。

Dispose of this monitor, then buy a monitor with a DVI interface, and connect it directly with a DVI cable. It is said that you use a 760 graphics card, and it is also a mid-to-high-end user, and in terms of positioning, you shouldn't use such a shabby 19 wide.

In fact, even if it can be used normally, there will be water ripples when playing games, and now the new mid-to-high-end graphics cards have long abandoned VGA, which is the wheel of the times and cannot be resisted.

First of all, has your graphics card been upgraded? If you have upgraded, DVI to VGA supports 1440x900! But from what you've described, it doesn't seem like there's a graphics card upgrade, which is why it's happening!!

Judging from your description, based on experience, your DVI to VGA connector is not of good quality, you can change it. Or switch to an HDMI to VGA connector. It should work out.

You can buy an HDMI VGA cable.

Is DVI for DVI-I?

Only the DVI-I connector can be connected to the VGA display using the adapter interface.

Buy this adapter: DVI-I to VGA adapter.

Notice what line do you have now? Is it a VGA cable or a DVI cable?

When buying an adapter, look at the condition of the adapter.

You can buy roots on **.

VGA to DVI

Not expensive. <>

The purchased graphics card should have an adapter, connect the monitor VGA cable to the adapter, and the other half can be plugged into the DVI interface of the graphics card, if you buy the graphics card without accessories such as adapters, then you need to buy an adapter or the corresponding monitor cable.

<> use DVI to VGA, please see for details.

Go to the Internet and buy a DVI to VGA cable and come back and install it.

There is a DVI to VGA line in the computer market, so you can use it when you buy one and install it.

Go to the local computer city to buy a VGA to DVI interface, usually ten yuan.

1 Just buy an adapter and don't bother.
