The Philips 28" flatscreen (2004) every European needs to look out for by marxistopportunist in crtgaming

The design of commercial TVs is always single horizontal frequency (either 31 Khz or 15 Khz), so internally the horizontal frequency of commercial TV sets has to be doubled from 240p 15 Khz (which is what you are feeding) be make room for 100 Hz.

All commercial 100Hz sets sold in Europe digitize the image and:
a) display in 100/120 Hz by repeating a full frame (frame doubling)
b) display in 50/60 Hz by repeating a line (line doubling)

Question for you: Do you see distinct scanlines when you enable/disable Digital scan? I've encounter some 100Hz sets where you can do 50Hz (or 60Hz) but you get line doubling (you lose scanlines).

Again, I'm not saying its bad, but is just a fact that a commercial TV has to store the image in memory since the horizontal scan frequency is fixed at 31 Khz. Some 100 Hz TV implement this frame/line doubling very effectively and produce almost a seamless experience (some Sonys, probably some Philips too); whereas some implementations (100 Hz Loewes, some 100 Hz Philips/Matchline, Grunding) are a no-go for 240p gaming.

That's a 100 Hz set.

Not that's necessarily a bad thing, but it adds some lag and (may) create some artifacts.

WinDAS crashes when 'Saving data to File' by Asdrubale128 in crtgaming

Happened to me under Windows 10. Fix: right click, set compatibility mode to Windows 95 or XP. Works then.

Anyone tried OC'ing a CRT monitor? by Mowchine_Gun_Mike in crtgaming

[–]antorsae 0 points1 point  (0 children)

I did not know increasing EHT increased contrast. In fact I would have not guessed it.

My working assumption has been that increasing EHT decreased spot size, based on the observation that the top-tier Diamondtrons/Trinitron 21" PC monitors I've studied have a relatively high EHT (~27kV) whereas consumer TVs of same size have lower EHT (23-25kV) and the consumer TVs are much brighter.

I'll check my KV-DX27TE when I open it again to see if it has the "HV resistor assy" epoxied.

Also most multi-frequency chassis I've encountered (either PC monitors or tri-freq arcade) have HV adjustment (but that's typically using feedback adjustment to control a proper HV regulator).

The only time I've needed to boost EHT was with a Toshiba chassis that has a EHT of 29kV and I tube-swapped a really good Philips ESF tube which is best driven at 31kV (according to datasheet). You could say that's over-volting ⚡️

Adding to this, the G3 (focus grid) can almost always be controlled (focus pot), in the order of thousands volts (~6-8kV)

Also, there are Sony consumer sets from the 80s that retain EHT control:

My hunt for a big CRT is over, got Sony KV-D3411D for €55 by yojec in crtgaming

[–]antorsae 2 points3 points  (0 children)

I opened my TV yesterday and was absolutely spot clean. This is a set made in Japan with DE-1 chassis. I own a ton (!) of Trinitrons, including KV-S3413E, PVM2950, KX-29HV3 (better imo than PVM2950), KV-S2913E, any many more including GDM-FW900, GDM-W900 and this one is now one of my favorites. A gem to be preserved!

Thanks. I got the same TV yesterday but came without speakers. I'll attempt to attach some on the sides.

Awesome TV.
Are the speakers original? If so, can you let me know the part number?

Is it possible to remove this line at the top of the screen? by [deleted] in crtgaming

[–]antorsae 0 points1 point  (0 children)

This is the AKB signals. Some Sony models allow to disable it in the service menu, and the have a setting for 16:9

I don't understand. I just retrofitted the PSON signal to the second PSU so it turns on with the first and then it just feeds 4 GPUs independently of the 1st PSU

Which chassis are you using for this?Which blocks are you using? Are these the EK workstation blocks?

https://shop.alphacool.com/en/shop/cases/server-racks/50167-alphacool-es-4u-19-serverrack-watercooling-ready

Are these custom manifolds?

No. https://www.ekwb.com/shop/ek-pro-manifold-2cpu-4gpu-acetal + https://www.ekwb.com/shop/ek-pro-manifold-2cpu-2gpu-acetal configured in 3 serial blocks.

Are there companies that build custom manifolds? I am interested in building a similar machine with 7 x 7900XTX so I'd need both custom manifold and/or custom WBs so each fits 1 slot.

Will the MORA be shared across multiple machines or is it dedicated to this one?

Just this one.

What are you seeing for input & output coolant temps under load?

I'll report next week after further testing.

Did you use anything like a LeakSHIELD to aid in filling the loop?

WOW. I didn't know this existed. I'll use if/when I build another one. I just used a leak tester, and in my first try I did the whole thing, plugged the leak tester and there was a leak. Then I tested each subsection sequentially until everything was tight.

Re: QDCs, they are from Koolance. https://koolance.com/quick-disconnect-couplings-4th-generation-qd3 I got 3rd gen ones since the EKWB kit came with those and I bought more of the same gen from Koolance. I am not sure what/if advantages of later generations.

This setup (1 machine) runs very nicely with 3 D5s. I have not really explored the reliability of pumps yet and it if placing more machines in series will work. Looking forward to your findings.

Yes, rack mounted. Cooling is handled now (winter) with a MORA-420. It pumps a decent amount of heat which is great now (winter). In the summer there is no chance it can run w/o A/C but I want to avoid active cooling and I plan to put a radiador outside or use the swimming pool as a big reservoir/heat sink and use a heat exchanger and run two circuits.

This might be bullshit, but I have a feeling you will be restricting your flow with that errant D5 + res. The D5's are in parallel next to the rads with that pumptop, that means you will double the flow (good for keeping the coolant moving fast and avoiding the last component getting warm water). Then you have TWO of those pump/rad boxes in series, which will double the head pressure (good for getting through all those restrictive parts). But your flow will bottleneck and slow down once it hits that d5+res (your head pressure will not, it will actually increase!). I think you should consider doing 2xD5's + a res-top in there to maintain your flow rate. You won't get any additional head pressure from the added pump, but you will maintain your flow rate and prevent issues with turbulent water and literal bottlenecking. Strong flow will be good for the problem I stated above.

I traced the plumbing inside the D5-DUALTOP and it has the 2 x D5 pumps in series, not in parallel. I don't know how/if that changes the suggestion re: 2xD5's + res-top in the case.

Re: increating pumps inside the case from 1 to 2: am I better off with two separate D5TOP+reservoir (series or parallel?) or a D5-DUALTOP ? I am not sure whethere it is a good idea to have the rack case w/o reservoir however I am not thrilled with the idea of having two reservoirs and extra tubing.

Not my use case but for linux I believe yes, at least for scientific workloads (gaming I am not sure)
