Is there an upper limit of resolution/refresh rate combos?

[LoserCard]

I had a strange issue where a custom resolution was only showing 2 out of the 4 refresh rates I had set in the option.txt file.

The resolution/refresh combos were:

2400, 1080, 60
2400, 1080, 90
2400, 1080, 120
2400, 1080, 144

Only after consolidating my list of needed resolutions/refresh rates to 21, the latter 2 options were available. Originally the option.txt file contained 91 rows (including the first "1" row). Is there an upper limit to the resolution/refresh rate combos?

Honestly, I didn't need all 91 rows, just thought this might be helpful to include in the readme if it is in fact a limitation of the IDD.

Did you leave a space (blank line) at the end of the options.txt file? And did you try using the XML in the beta file?

There is an upper limit to EDID files in Windows, so you may be hitting that limit.

I tested some resolution combo's to troubleshoot some issues I was having, maximum of 16 resolutions can be set in XML file
There could be other variables that affect this, but I don't need any more then 16 resolutions, I will attach XML
Last line in XML was duplicated until second display stopped showing in display settings
