GroggyExpulsion:
If i wanted to customise the MS9 preset to perfectly suit the MS8 monitor in groovyarcade is it as simple as making the following changes?

// Nanao MS9-29
   ms929
   
      crt_range0  15450-16050, 50-65, 3.910, 4.700, 6.850, 0.190, 0.191, 1.018, 0, 0, 192, 288, 448, 576
      crt_range1  23900-24900, 50-65, 2.910, 3.000, 4.440, 0.451, 0.164, 1.048, 0, 0, 384, 400, 0, 0

// Nanao MS8-29
   ms829
   
      crt_range0  15450-16050, 54-60, 3.910, 4.700, 6.850, 0.190, 0.191, 1.018, 0, 0, 192, 288, 448, 576

"The MS8 has a very tight frequency band in 15K mode , absolute min of 15.450khz and Max of 16.050Khz , optimal is 15.750Khz , it also has a tight vertical range between 54Hz and 60Hz.When ever they are operated outside of this range there is push and pull amplifier ( part of the little Hybrid Sync Module )that attempts to clamp the frequencies within the safe range , so if it is being run and absolute min or max listed above the amplifier / clamping section is working at maximum , if you exceed these limits these chassis most of the time are able to cope when the chassis is in perfect working condition...There is no gradual or accumulative damage , they just work as normal and suddenly fail"

Important notes on how the TV works with this preset:

* The chassis runs at a fixed horizontal and vertical scan rate of 33.75khz / 60hz and the stock config is to digitally process all input signals to 1080i or 540p with varying amounts of lag. When the HDPT register in the service menu is set to 0, the chassis allows any ~33.7khz/60hz resolution over the YPbPr inputs to bypass the MID (scaler) and the TV operates as a zero-latency fixed-frequency monitor. (The HDMI or DVI-D inputs are not compatible.)


* Although 33.7khz signals can go unprocessed, the chassis is designed with intentional hardware overscan, so some of the active image is cut off on all sides. This is rarely an issue when using 1080i sources as intended, since they almost always account for the TV's overscan by keeping vital elements within a certain safe-area. For the preset, it only uses 480 active lines out of the 540p signal, which is well within the area remaining after the top and bottom are cut off. Just by using vertical size controls in the service menu, the TV can be set for 480p - 448p to fit the screen exactly. The preset then fixes the cut off area on the left and right by adding specific horizontal blanking time, so no horizontal geometry adjustment is needed. This makes it minimally intrusive to return to the standard geometry settings for HD sources.
Service menu changes - geometry reference is SNES 240p suite monoscope:

* Set the APSW register to 1 in the 2170D-1 category for 480p to fit the screen



* Increase the value of the VSIZ register in the 2170D-1 category for 448p to fit the screen


Overscan comparison (note the corners):

* Standard HDTV timings - NO service menu changes



* Switchres calculated 480p mode - APSW set to 1 with NO changes to VSIZ



* Switchres calculated 448p mode - APSW set to 1 with VSIZ raised
