Dp to dvi to vga connection works?

Pun1sh3r

I got 1 used rx 570 which has only dp port working but my monitor only has dvi-i port (shown in photo).but I am already using cable which is dvi to vga .so if I buy dp to vga female then connect vga male to it .will it work

Why would you want two adapters in this case instead of buying a DP to DVI cable?

Please just get a DP to DVI. Don't use Analog (VGA, 15-pin D-sub) in 2023.

Why . resolution is not any problem (for me it still 2014 )

Analog is a problem.

 

Modern GPU-s provide a digital signal. Modern monitors (LCD, OLED) are digital devices, they accept digital signals.

VGA is analog, so you have to have an digital to analog converter on the side of the GPU (or an active adapter) and then an analog to digital conversion on the monitor side.

Every time you do conversions, there is a loss in quality and an increase in latency.

Using conversions makes no sense since your GPU already has digital outputs (DVI, DisplayPort, HDMI are all digital) and your monitor has a digital input (DVI).

Oh that's make sense ok thanks

Its a better bet to remove one of the adapters, go for DP to DVI directly, less likely to fail as well. Less iffy to troubleshoot I suppose.

But it should work

I sometimes wonder how we went to space on only 4KB RAM, and we cannot fix a simple issue.

The RX570 doesn't output any analogue signals. Your DP to VGA cable has a converter chip which takes the clean good quality digital signal and produces an analogue signal (VGA) .. the DVI-VGA passive adapters just re-arrange the wires between connectors because DVI connector has pins to carry the analogue signals of VGA. 

So basically you'd convert from digital to analogue, then inside the monitor the signal would be converted back from analogue to digital. 

 

Your best option would be to get a DisplayPort - DVI cable.

The next best option is a DisplayPort - HDMI cable, combined with a HDMI-DVI adapter (passive, no reconversion)  - sometimes this is cheaper, or more preferable because you may be able to reuse a DisplayPort - HDMI cable in the future, while a DisplayPort - DVI cable is less re-usable.

Their is one problem most dp to dvi is of dvi-d but my monitor is dvi-i .can I use dvi-d on dvi-i

DVI-D means DIGITAL ONLY 

DVI-A means analogue only

DVI-I means digital + analogue  DVI-I  = DVI-D  + DVI-A

 

Single Link means maximum 1920x1200 at 60 Hz , Dual Link means maximum 2560x1600 at 60 Hz.  

 

As a side note, off topic, HDMI standard was designed in such a way to be backwards compatible, to make possible those cheap passive HDMI-DVI adapters, but the limitation is single link only, so those work at maximum 1920x1200 60 Hz.

 

 

So your video card outputs only the digital part, therefore your monitor will only receive the digital part. 

 

If your RX 570 has a DVI connector, you can use a standard DVI cable to connect your RX 570 to the monitor, because the monitor has DVI-I , which includes the DVI-D part. Card outputs digital, monitor receives digital, it works. 

 

You can't use a DVI-VGA passive adapter, because these passive adapters are  DVI-A / DVI-I  -> VGA , they just take the analogue signal coming through their own separate wires and rearrange those wires into the VGA connector, so because your DVI-D connector on the video card doesn't put any signals on those wires, there's no analogue stuff to route to the vga connector. 

 

If you have a DVI to VGA cable that works, most likely it's actually a cable that has a converter chip like the ones used in HDMI-VGA adapters, which basically converts the digital signal to analogue. It wouldn't work otherwise because RX 570 doesn't have the circuitry to output analogue signals through the DVI connector.
