VGA technology was prominent when it first came out. Although these days it is not highly preferred. It is still a very common connector type for monitors. Many monitors these days have mainly HDMI connections, but at least one or two VGA connections as well.
Most graphic cards these days do not include VGA ports anymore since other better connectors have taken over. But even then, cheap VGA monitors tend to find their uses at times. Some of the major concerns regarding VGA connectors is what maximum resolution they support. And if VGA supports 1080 p and higher resolutions? This article attempts to answer all these questions in detail.
The Maximum Resolution for VGA
The original VGA standard had a maximum resolution of 640 × 480. Although on most modern graphic cards, the resolution happens to be 2048 × 1536. This resolution does vary according to the manufacturer. VGA cable is capable of 1080 p and higher resolutions but it is not recommended for it.
The situation is not so bad for 1080 p as such since difference between VGA’s 1080 p and HDMI’s 1080 p will not be so apparent. But as the resolution goes higher than this value, VGA does not prove to be suitable.
VGA’s maximum resolution depends on the source, since it is limited by signal source and VGA cable’s quality. But the reasons for VGA not being recommended for 1080 p and higher resolutions are stated further below in the article.
Does VGA support 4K?
VGA’s maximum resolution is 2048 × 1536 which is 2 K. Hence, VGA can not support 4 K which is 3840×2160. To watch in 4 K, you will need HDMI, DisplayPort, or DVI.
Issues with Higher Resolutions in VGA
The most apparent reason why VGA is not recommended for higher resolutions is because it uses analog signals. Since most hardware today use digital signal, more power will be lost in converting the analog signals to digital. This will most likely diminish some image quality as well.
It is recommended to check the specifications of your graphics to determine which resolutions are supported over VGA.
Using VGA for higher resolution will most likely not deliver the HD quality you are hoping for. With analog connections the signal quality reduces as the distance increases. So if you still use a VGA connector you can keep the cable as short as possible to get the best quality that it can give.
Another very common issue with VGA connectors is display issues. You might have to deal with display issues like interference, flickering, dimness, false colors, signal cut-outs etc. You can’t enjoy high quality media with VGA connector so VGA connectors are more so recommended for secondary monitors and for watching media that does not require much attention to details.
Maximum Refresh Rate on VGA
Anything more than 60 Hz on VGA for 1080 p will be difficult to work with. VGA has been rated 85 Hz on (800×600) which is very low resolution and does not help the situation. Hence, a high refresh rate on high resolution is not possible on VGA.
To Sum it Up
This article attempts to helps you understand the limitations of VGA connectors and their usage. In the modern world, there is not much scope for VGA since they are unable to support high resolution and hence, the results are unsatisfactory.
Although You might still find them useful as secondary monitors for watching media that does not require to be high resolution. We hope this article was able to help you figure out if VGA connectors are useful to you and their limitations.
