P3 SVGA display problem 1920x1080

[Mike K2MK]

I searched the archive and reviewed a 2012 thread on the subject of displaying the P3/SVGA on a 1920x1080 monitor. I thought this issue was resolved but I just puchased a 22" Asus monitor with a native resolution of 1920x1080 at 60Hz and the P3/SVGA does not fill the screen horizontally. It fills the screen completely vertically but leaves almost 1.5" of black screen on both sides. If I select 1440x900 it fills the screen fully. The 1920x1080-alt resolution produces an ill fitting display with unreadable text.

Hooking the monitor up to a PC produces a full display at 1920x1080.

P3 firmware is 1.26 and SVGA firmware is 1.16.

Are there any solutions out there or is everybody using 1440x900.

Mike,

If you read the P3SVGA manual, it states that "For faster screen updates
when using fixed tune
mode, we recommend setting the P3SVGA
resolution to 1440 x 900 or less. Note that
1440 x 900 will display correctly on
1920 x 1080 monitors."

That means that it will display a 1440 x 900 resolution OK on 1920 X
1080 monitors, but it does not mean that it will fill the display.

1280x1024 is about as high as I can push my 19" display
and have a full screen image that looks good.
I only use fix tune mode
ymmv

Hi Don,

I had read that note but it is in the current Rev D manual dated 9/30/12 which corresponded to SVGA firmware 1.10. There were two firmware revisions (1.14 and 1.16) in 2013 each of which added additional notes on 1920x1080 monitor compatibility. Plus the last thread on 1920x1080 monitors was in 2012. That suggested to me that the issue had been corrected in firmware. I just wanted to see if my experience was unique.

In the meantime, 1440x900 does work correctly and it does completely fill the screen. So it is satisfactory. The only negative is that the font size (even at font size 0) ends up being too large. If Elecraft wants us to use 1440x900 on a 1920x1080 monitor they should probably include an additional font that is extra small.

Hi Mike, The SVGA card uses an embedded VGA controller. This means that we're limited to two possible pixel clocks for the 1920x1080 resolution. Some monitors cannot sync to the pixel clocks and this causes the display to show the two black areas you noticed. Try setting manual mode on your monitor if it has the capability or try using a different monitor. We've had very good results using Acer monitors. 73, Paul
