This is my horizontal display setup. The picture quality is amazing for a 20+ year old 21" set. Golden axe shown here is emulated on the xbox with coinops.
Next I have SONY PVM set in the vertical position to accomodate vertical orientated games. Most of the vintage arcade games play in this orientation so I can use it for those as well as a huge library of vertical shooter/action games.
The image is pins sharp as per SONY standards and I could not be happier.
I kept my video scalers on standy should I need to display SD signals on a HD set. I plan to delay that day as long as possible.
The main screen on the front is a SONY commercial monitor built for long hours of use and maximum contrast. I have that running in 1080p through HDMI.
