Best VGA cable?

[VirtuaShenmue]

so the cable should be "rgbhv to component"?

Converting RGBHV to component (or vice versa) will always involve some sort of transcoder circuit, it's not something a simple cable can do.

so it's also not a "cheap" I guess?

New update:

I got the vga2hdmi adapter that you guys suggested



The diagonal interference is gone BUT the image flickering/tremble remain

here's a video of the issue:

it's like a VHS tremble.
I tested this set up on two different Dreamcast, same result.
This issue didn't appeared while using the VGA cable directly on a VGA monitor, so it happens only while the signal is converted to HDMi.

So what could it be the reason and how can I solve this issue?

Hello guys

Lately I decided to get a VGA cable for Dreamcast, to use with an HDMI adapter.
Unfortunately the cable was very poor quality, showing heavy flickering (especially noticeable on text) and various diagonal lines.
Probably it doesn't have any shielding.

It's one of those chinese cable you can get on amazon, that users reviews says were pretty good...

Now before spending more money on other bad cables, and before resorting to the expensive solutions, do you have any suggestions for a cheap VGA cable that actually works and doesn't have video issues?

Thank you very much

i noticed using an vga to hdmi adapter lowered quality quite a bit compared to just using a straight vga

Not sure i dont have that flicker at all.. maybe the wall power socket or something you have connected

The lack of correct pixel aspect from all cheap HDMI cables (Kaico, Hyperkin, Akura cable from Beharbro, Pound etc.), was what made me look elsewhere for a good solution, whilst still being cheap.

I ended up on ebay and found a professional video scaler for £20. (Retails over £200). Couldn't be more happy with the image. Perfect output on every game I have thrown at it. Always the correct aspect, handles 240p titles perfectly, no artefacts. This scaler has a better video chip than what is found in an XRBG mini. Looks better than that, too.

Sure, you will have more cables to deal with, but I seriously recommend having a look for something like this, as they can be had for a decent price, and absolutely none of the HDMI cable solutions can compare to the image you get from them. If you do not have a direct VGA compatible display, or do not want to invest in the DCHDMI, then a professional scaler is the best option.

why bother with a vga->hdmi adapter?
cut out the middle man.

no fuss no muss. better looking than any VGA signal

Exactly the same as the cheap Pound, Kaico, and the other cables, just in a fancy acrylic box.
None of these can output the correct pixel ratio of the DC leading to jailbars and a moiré patterns on the screen. They also fail on various games when switching between different refresh rates.

They are a decent and quick option if you want a minimal setup, with acceptable but not great image, but they look terrible in comparison to direct VGA or a professional scaler that has advanced video chips. Exactly what all these HDMI solutions lack.

Also, stating that the Gekko is better than a direct VGA connection is false on every level. Even a modern cheap brand HDTV that has native VGA but poor upscaling from anything that isn't the displays native resolution would be superior to this.

I paired my scaler with a fairly cheap, but well-made/shielded DC VGA cable that cost less than 10 Pounds.

Better to remain silent and be thought a fool than to speak and remove all doubt.

i switched to the akura after seeing vertical banding in both a cheapo VGA cable and the hanzo - haven't seen it since & the image looks quite good to me so I had chalked it up to the signal. is the ratio not 4:3? looks it to me...

apologies for not adding "in my experience", i guess, but i appreciate the namecalling.

In my opinion one of the best is Akura from Behabros. I tried the scanlines switch...a nice addition but i can't stand scanlines, i prefer raw image...
