P3 SVGA Query

I recently fitted a 23inch monitor to the SVGA output from the SVGA card in the P3, set up the resolution and it worked perfectly.
To save desk space today I purchased and fitted a 19inch LED monitor, the monitor wanted 1366x768 (or 1336) the nearest the P3 will give me is 1024. The monitor works ok but I notice a slight flickering, which is ok but slightly annoying.
Is there a reason that the software wasn’t set up for the resolution for small monitors? and is there a way I can reduce the flickering?

Re: P3 SVGA Query

I noticed a similar problem on a 1024x768 monitor. The flicker was
annoying on the waterfall section. A work-around was to turn the
waterfall averaging feature on in the SVGA menu, and set the averaging
value to the minimum (2). This eliminated the flicker and didn't smear
the waterfall too much.

Unfortunately, I wanted to use a higher value of averaging for the
spectrum display, and I didn't like the way it 'blurred' the waterfall.
My solution was to get a larger monitor which didn't have the obtrusive
flicker, turn off waterfall averaging, and increase the averaging
parameter to a value which I liked better for the spectrum display :-)

I'm using an "antique" 15 inch HP LCD monitor that I got with a computer
package ten years ago which also works fine, or so I thought.

I also get some flickering on the screen that I thought was just normal and
would have to live with it.

From what you say, maybe it's not normal.

Does anyone else notice the screen flicker? I've tried the monitor's menu
items but it's always there.

I had the same problem, Ross, with an old 15 inch
flat-panel monitor. Here is what Craig at Elecraft
suggested: "Turn on Averaging and set to 2. Turn
On Waterfall Averaging in the Menu. This will
resolve the "flickering"."

It worked :-)
