Default 1024x768 XGA vs 800x600 SVGA ???

Furuno's new 12" 3D display is 800x600 resolution at SVGA in comparision: Garmin's 12" 4000 series unit is 1024x768 resolution at XGA

(also note that Ray C120 and E120 are 800x600 SVGA; Lowrance 10.4" units are 800x600 VGA)

My PC knowledge tells me that the picture will be much better running higher resolution and using an XGA monitor.

i would think the higher resolution would be like regular TV vs. High Definition--i'm sure you'd agree that hi-def kicks butt over reg TV

Not sure how much better XGA is vs. SVGA, but i was under the impression XGA was newer and better technology.

Should the resolution play a significant factor for me in choosing my next plotter?
Does the pic/screen look significantly better on the Garmin vs. the lower resolution Furuno ?

At the 12" display size, I would not spend a lot of time worrying about the resolution unless you plan to watch DVDs on your plotter. The vector charts will look about the same at both resolution levels. There are many other factors such as the video board and software that have a big effect on display performance so honestly the best thing for you is to try out the units that you have in mind. More resolution means more to redraw each time the image changes (as when you zoom in or out or the boat moves) so it can have a negative effect on speed unless compensated for in other ways by faster processing.


I have the new Furuno NavNet 3D units and the image is very sharp and clear. To me it is not visibly different from the Garmin units -- but that is looking at charts, not photo or video.

The resolution difference is much more noticeable at larger screen sizes. That's why the Furuno "black box" NavNet uses 1024x768 since it can be used with 15" or 20" displays. I suspect one reason Garmin uses the higher resolution is so they can have common hardware for their 12 and 15 inch units, not because it is actually necessary on the 12".

Resolution is resolution - and the biggest benefit will come from having readable small text and the ability to display "fancy" graphics on screen - smooth curves etc. More pixels will typically result in a more pleasing user interface.

As Normans points out though the one DOWNSIDE to a higher resolution display is simply the amount of processing required to redraw the screen. In theory the manufacturer would have accounted for this but I know sometimes my 4212 seems a bit sluggish on the redraw and I am sure the sheer # of pixels has something to do with it.

So is it super-critical? No, but definitely take a good look at the displays in action before you buy. 800x600 would be more appropriate for a 10" display than a 12, in my opinion.

thanks guys for input. I'll try to compare side by side at a store when i get a chance.

any input regarding the diff. between XGA and SVGA? ;?

Sorry, misunderstood your question the first time - XGA and SVGA are not technologies, they are simply words to describe the different resolutions. Since you have the resolution numbers, they are a more accurate way of looking at things.

(in theory, vga means 640x480, svga means 800x600, etc, etc)

Here is a picture of my 4212 playing a movie, keeping track of the weather, and showing the depth.

I agree the resolution is less of a factor for this size of display. Its more important that the display brightness, contrast and anti reflective coatings are implemented correctly.

These factors make up the day light viewability of the display, which all manufacturers claim. Unfortunatley there is no published, real and consistent measure for all these attributes. So viewing the short listed displays in as close an environment to your own is worth doing if you can.
