Grab yourself an Extron!

Picked up an Extron RGB 201 Rxi from eBay last week.

This unit was recommended to me as a way of centering the picture horizontally on my Blaupunkt which doesn't actually feature a H position pot on the chassis.

This crafty little unit only cost me $20 but it can do some amazing things! Firstly, it does the desired H position control very well. There is a HUGE range of adjustment available. There is also a V position control that shifts the image up or down one scanline at a time. Really cool. As a bonus, there is a Level Boost pot and a Peak Control.

The Level Boost is really cool for controlling how dark the scanlines are. With the control up high, the image tends to saturate and bleed. With the control down low, the scanlines are far more defined. Neat!

The unit also features a horizontal and vertical frequency readout on the front LCD. Very cool for confirming that your GroovyMAME modelines are delivering what they advertise:

Around the back, the unit features RGBHV on BNC connectors. It can also run RGBS meaning that I can possibly ditch my UMSA adapter in the future (provided I make up a BNC to SCART cable).

Overall, a very cool tool for those that are running native res and refresh. Highly recommended!
