I also got a VGA to HDMI adapter, that works even on 720x400 and 320x200, and also a HDMI capture stick. Also the old VGA-HDMI adapter I had (that broke, the problem was yellow tint on image and blue channel was absent) didn't supported 720x400 and 320x200 video modes. Now with the new VGA-HDMI adapter I can capture old DOS games and see the PC BIOS.

Does it convert 70Hz to 60Hz or pass it through as is ?

Can you share a link ( or at least some keywords that one can use to find it) to where you got it from ?

I don't know if it's converting 70 Hz to 60Hz or if pass it thorugh as is, but it works. Also, this adapter (1st picture, the new one) I got it from some Romanian marketplace. Try to find VGA to HDMI adapter as keywords.

I hope you are more lucky than me with that capture stick, two broke on me because they overheat very much.

Yes. I am lucky with that capture stick, it doesn't overheat very much, it is warm or hot sometimes, but not too hot to be untouchable, but it works. I am satisfied with it.

Hello all!
I just bought a DSC-301-HD for a decent price and I wonder if the output will be sharper than my RGB-HDMI-300-a, has anyone compared the two?
For reference, I'm using the 300-a to capture my 486 PC VGA output (using a ezcap Gamedock Ultra as the capture device)
I also have a Gefen ext-vgaaud-2-hdmis and the image quality is spectacular, but it has some really annoying notification when the resolution changes that can't be turned off.
Any thoughts?

I had no luck at all with the cheap sticks, in terms of dos resolutions and frequency. Did the job though for 640*480 and up though in win98,.but I doubt these cheap sticks are the best available option for this purpose.

I picked up an Altona At-500d with version 6.03 firmware. It is happy with dos resolutions and frequencies. Inability to adjust sharpness, and it's as fuzzy as the cheap sticks.

Mine doesn't seem to have the colour issues others have mentioned in this thread. Black is black. Reasonably happy with it.

Hola - how does your DSC-301-HD compare to the RGB-HDMI-300?

Sorry for the stupid question, I am new to that topic. Is the Extron DVS 304 RGB Scaler a suitable solution to do scaling from 320x200 to a VGA-connected monitor ?
