1080p through VGA input

[seiny]

Is it negative in any way to use the VGA input instead of say DVI on a 1080p monitor?

Some snobs will say it's bad. But honestly I have two monitors side by side right now. One using dvi the other vga, both using 1080p. I see hardly any difference. There will be many posts saying otherwise, just try it for yourself and see what you think.

 

Edit- 1500 posts, woot!

It worked for me, i didn't see difference between HDMI and VGA in 1080p.

contrast ratio is terrible and bad color reproduction is what i noticed when I personally tried it out.

may just be me, but when my GPU is at full load and displaying through VGA, I get weird distortion, but when I output through HDMI, it's fine.

1080p over a VGA works fine, but you shouldn't use it. Always use a digital connection if you can.

Well this monitor I have only has VGA out plus I kinda got it for free so I can't exactly complain

Another thing is the display doesn't look so great, how do I optimize it? it's looking a little dull and washed out on windows 7

 

The previous PC it was on was windows 8 and there was no problem, looked good, saturated

The problem is that analogue connections like VGA can be influenced by many things, the signal is never perfect and the image quality and accuracy can easily be degraded depending on the cable length and quality. On a digital connection that is not case, the signal arrives and is interpreted as intended.

 

Think about how stupid this sounds... your graphics card generates a digital signal which it then has to convert to analogue so that it can be sent over VGA, then your monitor has to re-convert it back into digital so that it can process the image and display it. Wouldn't it be better if it was just sent digitally in the first place?

VGA is analog RGB, so cable and connector quality often have a detrimental effect on color accuracy. you get what is called "crosstalk" between color channels sometimes, especially as cable lengths increase, adapters are used, or connectors wear out.

HDMI, DVI, DIsplayPort etc. are all Digital connection where VGA is analog.

with digital the difference between a 1 and a 0 is very obvious and a bit of interference will have no effect. on VGA transmitting 8 bit color, 244 and 245 are not so different and interference may cause the color accuracy to falter.

VGA will carry 1080p signal but it is less than ideal because it's analog nature allow interference to play a part in the signal so color accuracy is held back.

conversions between analog and digital are almost always lossy, so converting twice is twice as lossy, as your GPU and Monitor are digital(unless you are using a CRT)

There must be something I can do? Besides a new monitor of course

Ran VGA 1080p for 4 years, now I'm running DVI 1080p for the past year. No difference to be honest (except that the new monitor is LED) but VGA does give very good quality up to 2m of cable length. At 5m or more you will notice quite a bit of degradation in quality.

Here's something: I recently tried to hook up a 1080p TV to a PC trough VGA and it only went up to 720p. :mellow: After that I used HDMI and it displayed all 1080 of the p's.

Did you even read the thread?

I mean on a monitor that only has VGA, the best possible image for the monitor is through VGA, so go for it. if I was buying a new monitor I would guy something with HDMI, DVI, or preferrably DIsplayPort, but for a free monitor you can't really complain.

If I had a decent LCD laying around that was only VGA, I would probably use it as a secondary screen.

That's normal, tv's normally don't scale well when connecting to pc's and it may be your tv is not full 1080p

You quoted me before I got to add more info.  It's full 1080p. After the VGA I used a HDMI cable and it worked normally, at 1080p.

The best thing you can do without upgrading your monitor is use a short (not excessively long) good quality VGA cable.

Fine :rolleyes:

What should I be looking for? I have a 1 meter (approx) standard cable that came bundled with a monitor

My monitor doesn't have a DVI port. And my GPU only has DVI ports. I'm using a DVI-to-VGA adapter. I guess it can't get worse than that, can it?

 

I can do everything I need without a problem. However, my laptop screen is so much brighter than my monitor. I guess it has to do with the technology of the new screens though...

I've been wondering about that as well, it's like the laptops are brighter and clearer and these monitors have a brownish look on white pages

I guess we've just not been using really good monitors so laptops look so good to us, haha!
