I have 2 lumagen scalers at home.
Up until now I have been using the HDQ as a scaler and enjoy the advantage of D/A converter that it has.
The disadvantage of the HDQ are
1. Can except up to 1080p 24Hz (i need 60Hz)
2. Limited gamma corrections.
therefor. Im thinking of changing to the other lumagen that I have (Radiance XE 3D).
I will need D/A converter
Does the simple and cheap converter do the job?

The item pictured has a male DB-15 plug that usualy associates with devices with VGA INPUT not output, so I'd say this one is a VGA->HDMI converter and not a HDMI->VGA what you'd really need

You're using an analog display? Which one?

I would stay away from very cheap ones as that kind of negates the point of using a good quality scaler if you're following it up with the cheapest D -> A converter. Moome makes some good quality ones for CRT projectors and may have other solutions too (You can email him at moome@curtpalme.com).

I've had the white chinese HDMI converter, in its stock form it did not properly resolve 800x600 in bandwidth, but it was able to handle 1080P72Hz signal, though it was specified only for 1080P 60Hz.
After removing the output filters on the RGB lines then the bandwith increased a lot, so much it could properly resolve the 1080P 72Hz (with some inherent peaking), but the output is not very strong either. I think this is probably also based on the chinese EP94Z1E converter chip.
