Posting my XP37 Plus here for sale. It has gone through many restorations and repairs to the internals. The outside front bezel has been cracked, as you will see in the pictures, but the integrity of the case has not been harmed. It is not brittle in the slightest, and is holding up to be sturdy. The back of the case or sides have no damage at all. I do not have the skill to repair this bezel, so I will leave it to the next owner. I will include pictures here and the write up that I made for the monitor's mods and repairs. But here is a brief outline:
January 2024 - Initial Inspection and Fan Mod: We took it fully apart and inspected all the boards as well as installed the Noctua fan mod to the monitor. No other repairs were done at this time.
May 2024 - Fully recapped the power board minus 3 caps to fix issues with the power delivery system. Since it is the hardest board to get to, we prioritized doing this and the monitor remained stable until today.
April 2025 - Fully recapped the Dynamic Focus, Flyback, and HV board. Recapped the neckboard minus 3 caps. Applied electrical tape to the transformer on the HDef board to prevent any noise from coming out of it.
Write up:
A brief introduction, this is a very rare large CRT presentation monitor capable of a 96kHz maximum horizontal frequency. It's the only obtainable presentation monitor on the planet capable of a frequency this high, among the only ones at this size. It is also capable of 15kHz, meaning it takes 240p natively through RGB. It is 15kHz, 30-96kHz. The vertical maximum is 120Hz, allowing a resolution of 720p@120Hz or 1440i@120Hz. I believe it to be 1 of 4 known samples in the United States, and there are around 10 or less known worldwide.
I repaired and restored this monitor with the best of my ability, and the great assistance of one of the best CRT calibrators and repairmen on the planet - slick. I flew him in, and we worked the best we could on the monitor. He is known for working on many high level CRTs and being flown out for calibration or repair.
The power board on this monitor is known to be the absolute hardest board to get to on this monitor, because you have to strip everything down and tilt the tube forward to unscrew the cage. We have fully restored that board, minus about 3 caps. There will be no need to maintenance that board in your life time. I was responsible for recapping the neckboard and dynamic focus/high voltage boards. Those were easy enough to get to and diagnose by myself. Every board except 1 has been serviced, fully recapped, and scanned to the best of our ability without a service manual, because one does not exist for this unit.
Upgrades that were done include a full Noctua fan mod overhaul, courtesy of a good friend. He instructed me on how to rig the fan controller board to allow for installing other fans. I am unsure where this mod originated from. Before, the monitor was quite loud with the old industrial fans included. Now, with the case fully on it is quite silent. There is a very faint hum because the power board fan is very strong, though it is still a Noctua fan. This one and my friend's XP37 are the only ones in existence with anything of the sort.
The monitor has a remaining issue that we cannot fully fix due to the service manual being absent. -The dynamic focus circuit will still have moments where it will defocus parts of the screen for less than a split second and go back to normal. I am not sure if this is normal behavior, because other XP37 owners have not observed this beast closely enough to point it out. My friend will get back to me on if his does this. The focus circuit has been fully serviced, and the flyback is healthy. This is a minor issue.
These are the only issues that remain after doing our restoration to the monitor.
The monitor will be perfectly to D93 and D65, both color profiles on the RGB1 and RGB2 inputs will be color calibrated so you may switch between them at your leisure. As you can see, there is damage to the outer case on the front. I am not sure exactly how it received this damage, as I bought it from a Studio a while back. There are very light scratches on the screen as well that are absolutely not visible while the screen is on. They do not rainbow. The bezel can likely be fixed with the correct means, but I decided to let the new owner decide if they will keep it as is without disturbing the original material, or attempt to fix it. It absolutely does not impact usage of the monitor and is purely visual. The back and side casing of the monitor is in perfect condition and has no damage.
As for my opinion, this is definitely the sharpest slot mask monitor of this size I have ever seen (aside from a friend's 32" NetTV, but it has VM that effects the picture). The pictures featured in the ad are in 240p and 480p. The monitor is absolutely amazing in both those resolutions, but it can also handle high resolution very well. Upon request, I can show you pictures of 1080p, 1600p, or 1440p and the likes. It's the only presentation monitor obtainable that can do 1440p. I like to use interlaced resolutions on it through my computer, since it has a VGA input I can directly connect it and do anything I want 30kHz-96kHz. And I keep consoles connected to the RGB 2 input. It's a very amazing monitor, but I am exiting the space. Please if you have any questions or would like to set up a demo, do not hesitate to let me know.
I would appreciate serious buyers only to ask for an in-person demo. At your request, I can give you specific pictures of grids, test patterns, or any specific games I may have. Specific pictures of the unit itself.
