2080 Pixel rate too low
The pixel rate is below the minimum rate supported by the
generator.
Increase the value of HTOT.
Increase the value of HRAT.
2090 Horizontal total not even
The generator does not support an odd number of total
pixels per scan line.
Make the horizontal period (in pixels) an even number.
2091 Horizontal total must be multiple of 4 at pixel
rate
The generator does not support horizontal pixel totals (active
+ blanking) that cannot be evenly divided by four (4) at the
given pixel rate.
Make the total horizontal pixels per line to be evenly
divisible by 4.
Decrease the pixel rate.
2130 Horizontal active too small
The number of active pixels per horizontal scan line is below
the minimum supported by the generator.
Increase the horizontal active pixels.
2140 Horizontal blanking too small
The number of blanked pixels per horizontal scan line is
below the minimum supported by the generator.
Increase the horizontal period (in pixels).
Decrease horizontal active (in pixels).
2141 Horizontal blanking too small
The number of blanked pixels per horizontal scan line (HTOT
- HRES) is below the minimum supported by the generator.
Increase the horizontal period (in pixels).
Decrease horizontal active (in pixels).
2150 Horizontal blanking too small
The number of blanked pixels per horizontal scan line (HTOT
- HRES) is below the minimum supported by the generator.
Increase the horizontal period (in pixels).
Decrease horizontal active (in pixels).
