Wells Gardner 27" Arcade Monitor: NO LONGER IN PRODUCTION


Please note, due to limited demand for CRT technology, Wells Gardner has discontinued all CRT monitors with no plans to start again. We cannot currently, nor anytime in the future be able to source Wells Gardner CRTs. We have kept this page online due to the numerous inquires we receive about availability.

The good news is that we've found a great replacement: please see the 29" CRT Monitor or HD LCD here.

Common Questions

How is your pricing so competitive?

A: We are using this same monitor in the X-Arcade Machine, so our volume provides a very competitive price.

What is a Monitor Bezel?

A: A bezel is the decorative black plastic material which covers the areas outside of the monitor glass to give a clean appearance to any cabinet. This bezel can be purchased and used with any 27" flat screen monitor. If you are replacing the monitor "only" and you already had a flat-screen monitor/bezel, you won't need to include the bezel. If this is a new project, or you are switching from standard to flat screen, you will need the bezel for $39.95

What Machines can this be used to replaced?

A: You can use this to replace any 25-27" commercial arcade machine and upgrade to the new digital flat screen.  This is also the monitor of choice for creating a MAME Arcade Machine Cabinet.  Please note you will need to purchase the flat-screen bezel for enclosing the monitor.

Should I use this display for the Mame Machine I'm building?

A: If your intent is to play classic arcade games, there is no better option. It's the industry standard, most authentic arcade monitor available. Lower-priced options exist, but none provide a performance even close to the Wells.  

Should I use an HDTV or Plasma/LCD?

A: This is by far the most misinformed question we receive. Other solutions using LCD or Plasma HDTV come nowhere close to delivering an authentic arcade experience.

HDTV displays are designed for the "16:9 Aspect Ratio," games will be displayed in blacked-out vertical stripes (Letterbox) on each side of the screen, and not provide authentic scanlines.

HDTV displays are incapable of displaying in the original arcade resolution and refresh rates from the 70's and 80's. The Wells is a tri-sync display, a small feature which is not incredibly expensive, but simply not available on any HDTV on the planet.

Leave your next generation game system connected to your big screen HDTV, use a real arcade monitor for your arcade machine.

Do I need any special transformer or adapter to power my D9800?

A: No. The Wells Gardner 27" arcade monitor plugs directly into an ordinary power outlet, just like any other computer monitor.

Do I need any special adapter for my computer?

A: No. The display plugs directly into your computer's video card. Note: The connection is VGA, not DVI.

Do I need to use scanlines with the D9800?

A: No. The display has natural scanlines; no software scanlines are necessary, providing authentic and realistic visuals.

Do I have to do anything extra to run Windows™ or OSX™ on the D9800?

A: No. The D9800 can run any os just like a standard computer monitor.

Can the D9800 display 32bit color?

A: Yes. The D9800 can handle 256-32bit color.

Can I play games or watch DVD movies on my D9800?

A: Of course, this is merely an industrial grade computer monitor.

How do I get my D9800 to run in EGA or CGA mode?

A: The D9800 features a change over adapter to allow for strict CGA or EGA input.

What is the warranty and how does it work?

A: If your monitor breaks within 12 months, we either ship replacement parts or a replacement. We also provide a pre-paid return shipping label so you don't incur any costs returning the defective unit. (48 States Only) Interational customers are responsbile for all shipping charges both ways.

How big is the 27" D9800?

A: 24" wide, 22" tall, 20" deep. Display size is 28.5", 27" viewable.

What are shipping charges?

A: The charge in USA 48 States is $69.95
