Here are some pictures of the monitor with games running.
The XV29 seems to be working pretty well, however I've noticed some weird things about it, and I wanted to get some advice.
The image on it seems really good, and has only minor problems that don't really bother me. Also, I think these problems actually may be caused by the source, not the monitor; I possibly didn't notice it with my other monitors because it's harder to see on a smaller monitor.
Besides that, I've noticed the monitor making some sounds that may be normal, but they sound kind of weird to me. For one thing, any time the monitor is turned on it makes a slight buzzing sound, which seems to be coming from the middle to rear of the tube. It isn't very loud, but it's noticeable if you listen to it in a quiet room without any speakers on. I don't know if this is normal or not, though I can't remember hearing another monitor making a sound like that. I read somewhere that a buzzing sound from the tube might indicate that the enamel that holds the wires (I can't remember what they're for) that are attached to the side of the tube - that enamel might be cracked or damaged in some way, and is vibrating. However, I can sort of see inside the monitor between the slats on the side that are supposed to allow airflow (it also has a fan, I think, which is very quiet), and the enamel seems fine - I don't see any noticeable damage. It could also be caused by faulty caps, but all of the caps I can see look fine. There is some weird looking stuff on the board on the upper middle part of the tube, but I think it's just dust. I can't rule out the possibility that the dust is what's making this sound, or dust in other parts of the monitor.
I've also noticed some weird sounds when it's obtaining a sync or changing resolutions. It's a fairly quiet, but noticeable high pitched squeaking sort of noise (it's hard to describe), which usually lasts a second or two. I've also noticed it making a different sound with the N64 in particular; it's a similar kind of squeaking sound, but it also sounds like clicking, and it stops momentarily in the middle - which worries me a little, because it could mean that the monitor is almost failing to sync but still manages to do it. Again, I don't know if any of that is normal or not.
None of the things I described seem to affect the functionality of the monitor; everything seems to work fine, and the picture looks very good. I'm just wondering if any of these things could be indicative of a problem that might get worse over time.
Another thing is that, while most of the systems I've tried (GC, Genesis, DC, Saturn, N64, Xbox, SNES) work just fine, there are a couple that don't, as well as a couple that I haven't tried yet because I don't have the cables I need (and won't work anyway, until I built a new adapter). The ones that don't seem to work at all are my PC Engine and my MVS. The monitor seems to attempt to display a signal from these systems, but no image shows. I've tried both RGB inputs, and get the same result. The MVS is connected to a supergun, but the supergun works with my other JAMMA system (Sega ST-V), so that probably isn't the problem. Both the PC Engine and the MVS worked fine with my PVM over RGB, though I recently noticed the MVS's output looks a bit dark compared to my other systems. The PC Engine works on this monitor if I use the composite output from the IFU, but not if I use the RGB output from the CoreGrafx (it's been RGB modded). I don't know why these systems don't work, but I'm thinking it could have something to do with the sync output. What do you think could be the reason, and how can I get them working?
So, I really just want to know if any of those things I mentioned before are something I should be concerned about, and why the MVS and PC Engine don't work. Any advice?
