    How would the PVM-2950Q and the NEC XM29 handle luma as sync?. From reading the datasheets for the LM1881, it looks like it can only strip sync from CVBS (Composite Video). Thinking of picking up one of these 2 down the road if they ever show up for sale around me.

    So since you're getting a QM, I'm assuming you're in Europe somewhere. I have a US model 2950Q and it does not accept a composite video signal as an acceptable composite sync source. You'll need to use a sync stripper. I have used the cable from retro gaming cables with the built in stripper and it works great. You can also save a few pounds and build your own if you're handy with a soldering iron. I have multiple PVMs and I didn't want to spend $60 for a cable for each monitor, so I built two of my own. :)

    Actually in Australia, not Europe :)

    I could build my own sync stripper but I think I'll just get the premade cable for now. I've only got one PVM that needs the BNC to SCART, my other one has SCART and accepts everything :)

    What's the 2950 like? I'm a bit excited, will be picking it up on the weekend :)

    I like to call it a "Pro-sumer" model. The 600 line tube is much better than any consumer grade Trinitron TV of that era, even the XBRs. But the picture quality isn't as good as a PVM-1954Q/PVM-20M2*/PVM-20L* or a BVM. It's very much a studio or presentation monitor, great for viewing in a professional environment, but not for any sort of post-production or color correction work.

    Well, I don't plan on doing any post production work, it's purely for RGB gaming :) My 2730QM looks great, only 400 lines I think and doesn't do svideo or component, it also has no controls for size and position, well, there are, but only trimpots inside. The 19 and 20 inch PVMs and BVMs are a bit small for my liking. My 27" is a nice size and the 29" should be even better :)

    Got my 2950QM today, love it! It's in great shape and the screen is perfect. Is there any way to find out how many hours it's been on?

    My c64 looks so good on s-video, the best it's every looked. RGB and component are also amazing. I think that's it for CRTs for me now, I've finally found "the one". Long may it live, I'm not sure how easy it is to find someone to repair if the unthinkable happens.

    Unfortunately PVMs do not have hour counters, so there's no way to tell how much use it's gotten. What year was it built in? Mine is from 1995. If you have the means, I recommend changing out the capacitors, even if the picture is good. The 2950Q/QM chassis is built closer to consumer specs compared to the rest of the PVM lineup. Most capacitors are only 85 degree, rather than 105, meaning they won't last as long under harsh conditions.

    I would like to ask if the PVM-8020 supports PAL input. (I have a fairly short window of time to buy one, so a prompt response would be appreciated). Thank you for any assistance.

    PVM-8020 is a really old model that doesn't support RGB. I can't find any info on it, but I know that the PVM-2030 and PVM-2530 from that same generation do not support multiple formats, so it would be safe to assume that if you're buying a US model 8020, it probably won't support PAL.

    Thank you. That's unfortunate, but good to know.

    How can I learn how to use the service menu? My 2950QM is great, but I'm a bit fussy, so it could be better. The picture curves in a bit towards the bottom, especially on the bottom right. I can get into the service menu, but have no idea what I'm doing in there :)
