Well, my G90f's vertical collapse is pretty much permanent now. Hopefully, I can find a repairman to sort it out if I can't myself. It was an awesome experience while it lasted. After mainly using a CRT for months, everything feels so laggy and blurry on my LCDs... I don't think I'll be able to...

There are some especially good (high DAC pixel clock) DP to VGA dongles that are USB C instead of full displayport. There are full displayport options that are just as competent. But, there are less of them, and they seem to be out of stock more often than the good USB C options.

I know high horizontal scan rates are hard on CRTs in general. But, can they cause or lead to vertical collapse?

Hahahaa, me too. :smuggrin: That reminds me, Ashun recently published a great video on LCD response times:

True. ANSI contrast would definitely not be that good. But, not all images look like an ANSI checkerboard, so the huge potential contrast of 3400:1 can really help.

The point of zero-level blacks is for the cases where there is indeed enough black space for light-bleed to not drown it out as much. Sure, not all that common, but very noticeable in the instances where it is the case. My blacks really are still mostly zero level when I display the OSD. Of...

Ah ok- I have tuned it for zero-level blacks. Yeah, his was an IPS. I wasn't all that impressed, really. I commented on how low its frame latency was, but I didn't talk about how blurry things still were. LCD pixels just can't keep up with 240Hz where it matters for little details. But alas, I...

Hahaa. My friend recently got a laptop with a 240Hz screen and brought it over for some LAN. Of course, it still just couldn't compete with 720p 125Hz of my G90f in terms of motion clarity. Though, he was actually impressed with the colors more than that. But, that's probably just cause his...

Alright

Yeah haha. I'll still keep CRTs around when a display finally objectively trumps them in every way (minus flexible native resolutions. That's just physically impossible with anything other than a CRT atm), because of how legendary CRTs' decades of relevance were. Something to be remembered...

Alright. I'm curious how much life I can get out of it without replacing the IC chip, though. Even if I find the right part (no clue where to look yet btw), I'd probably hold off swapping it out just to see how long things would last. Unless that could cause issues for other components, then I'd...

Not in terms of motion clarity. It'll take awhile before any display is truly comparable. We've reached comparable black levels with OLED. We've reached comparable input latency with modern gaming TN LCDs. But, we have not reached low enough pixel transition or reset times to have comparable...

I see, ok. What does it mean if the vertical collapse happens only every so often, yet seemingly more often with higher horizontal scan rates, vs. being constantly vertically collapsed as long as the CRT is on- like in most of the examples I found on the net? Is it possible to repair this issue...

I see, thanks. From what I've read, it's an issue with vertical deflection caused by failure of the vertical IC chip. According to this article: https://riddledtv.com/journal/Vertical/ - I can fix the chip by re-soldering the bad connections. Would that be easier than just finding and buying a...

I have an issue where the top half of my ViewSonic G90f will go black as a very bright horizontal white line quickly swoops down to the middle of the screen. It only seems to happen at high horizontal scan rates, which is worrisome. Any ideas as to what this might be? It happens very seldom and...
