    TFTCentral on "fake" HDMI 2.1 and the hdmi org's response saying that's fine

    If you have to pore through a specsheet in the hopes a device does something it probably doesn't do it. It certainly wouldn't do it reliably. Have some trust in the marketing departments of these companies. HDMI 2.1 means the HDMI consortium got paid, nothing more or less.

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    ABL and other protections are inactive during the WPB. So if you set things wrong initially the tube can be overbright in later phases. The initial adjustment is not made using instrument data, but the later ones are so if they don't line up redo it from the start. If you do the initial steps in...

    It's entirely possible. Any rich collector in Europe could have put up that amount and by then these were well known and sought after. But it was also supposedly in an attic for that long so the idea of it being "new" old stock may be a bit farfetched as it would've aged enough to be old old...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    Hey there, despite having done a WPB only recently I've already forgotten the precise details to this step. AFAIK if you meet the luminance targets on all the steps (high and low) you will be fine. It asks to track color accuracy with brightness on full white to confirm that, but contrast I...

    Philips Momentum 55' vs. LG CX

    Well the CX has ABL so on a bright white screen you will get a dimmer image than you are used to with an LCD. In typical viewing like movies or games it'll be about as bright or better than the one you had. It's plenty bright, it's just not 1000 nits like the new displays can do. The Philips is...

    Philips Momentum 55' vs. LG CX

    Well the CX is an OLED with "infinite" contrast and as many dimming zones as it has pixels, but it's not as bright. The Momentum monitor has no FALD so it's just 5000:1 VA contrast at best, though it gets up to 1000 nits maybe. The OLED is a bigger qualitative upgrade for you over your old...

    The tube and power caps still hold charge for some period of time that I can't tell you for certain. Maybe wear rubber gloves for some minor protection. It is fine as long as you don't critically fumble and contact those areas The MOSFETs are located across from the FBT at the bottom of the...

    I had a problem like that with a transistor in the horizontal deflection after a mishap in WinDAS. Q501 I think: The monitor would work until the transistor got too hot and completely shorted out with the burning smell being the first sign. Before I'd had that all figured out, I let it go...

    I attached the North American version of the FW900 service manual, but the components you are talking about probably are unchanged. Anyway I have no experience with that particular issue, but replacing enough relevant components will probably take care of it.

    Sony GDM-FW900 - NIB

    Yeah it's true. 60 nits SDR is an order of magnitude less than most people are used to coming from modern LCDs and the latest OLEDs. So it is dim. Also the instantaneous brightness of CRT is very high for each trace to to produce a coherent image. That's different from having a duty cycle that...

    Sony GDM-FW900 - NIB

    Yeah the total light output of a 48" OLED at 60 nits (cd/m^2) is approximately 2x higher than a 24" CRT (assuming the same aspect ratio) at 120 nits since the OLED has ~4x the area. At the same perceived viewing angle, however, the lux is the same (since the diagonal is only 2x larger). But the...

    Yeah laser projectors and rear projection are a pretty good but they have their own issues, primarily how you deflect the laser light still involves some form of physical device as the photons can't be electromagnetically diverted the way a stream of electrons can. There's also the speckle...

    Sony GDM-FW900 - NIB

    Honestly the FW900 (or any other modern CRT for that matter) doesn't look that great. It looks good, but from the hype job video that DF did (or didn't intend to do), people think it can make 720p look like 8K or something. It does not. Jaggies will still be jaggies at low resolution despite the...

    Yeah the bids are suspicious. Could be a rich collector or a troll. The fact that it was made a private listing means we probably won't ever find out. Even if the buyer were to pay 35K for the monitor, the fees would be exorbitant and the seller would have an incentive to make the transaction in...

    Sony GDM-FW900 - NIB

    Looks like it's been in an attic in Germany for 20 years, who knows if it even works. Private listing so no idea what the bidders are about. Will hit $5000 easy. A used model in what looked to be pristine condition sold for nearly $3500 in Japan just a couple of weeks ago. I'm sure there are...

    If you don't get any other opinions I would redo the soldering on that socket and clean up that residue. No clue otherwise. From some cursory googling it looks like the TVs can be fixed easily be replacing that IC, but didn't find anything relating to the FW900.

    Nothing premade unless someone can sell you something like what they mention here, but get yourself a reputable TTL adapter with a chip that is known to work properly with Windows 98 with whatever drivers and search the thread for the pinout. It's only three pins you really need. The 5V was to...

    Meanwhile here's an F520 FBT which definitely does not seem as compatible and the way all the boards are layed out is completely different.

    I was brainstorming on the basis of the observations about temperature and humidity. Maybe if moisture infiltrates the spark gap that would change the breakdown voltage, but if you're in nice and arid Utah with the heater on that oughtn't be the problem. Temperature and thermal and mechanical...

    I had that one time. Did not shut down the monitor or smell any burning but yeah I had to readjust it the raster since it got smaller after the pop. It was with a regular DVI-I analog output from the card so no chance it was an adapter issue. I think it has to do with humidity and temperature...

    I can kind of see the "crosstalk" implied here: Maybe the phosphor decay in the top part is what they mean. caption "CRT" at 20:39 of the above video (a5hun's XG270 review). Overall I think Mr. Rejhon is almost unimpeachable. If you have followed his work from Blur Busters onward he doesn't...

    Flight Simulator on a single display - how?

    Single screen is more than enough to practice instrument-based approaches which is what "serious" flight simmers do. Basically looking at your instruments the whole time like a commercial pilot would be doing without visual references. Triple-wides give you peripheral vision and the kind of...

    CRT vs LCD vs eyesight?

    It turns out that brightness is actually good for your eyes. Particularly in the high-energy range. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5233810/ The "damage" from staring at LCDs and CRTs seems to be more about prolonged viewing depriving you of the high-energy light radiation that...

    Thanks for the write up. I'm wondering why people are having problems with WPB now. I don't remember anyone having these issues a few years back. The successful ones I did were all on Windows 7.

    It's probably dependent on temperature and humidity and such. My opinion is that if the thing looks good after it stabilizes it should be fine, that's my penny for ya. Going to end up causing more problems trying to diagnose things on the basis of descriptions of what other people are seeing...

    There never were any pics posted so it could be so it could be entirely within specs, whatever they may be. As long as it looks good after warmup there isn't really an issue. WPB may help balance all the different numbers behind the scenes, but I haven't seen a definitive comparison between the...

    Lack of 16:10 options is DEPRESSING

    I prefer the way TFTCentral breaks down lag. The RTings times are actually confusing since they are relative. So yeah the lag for the CX is actually only 6 ms which is not bad at all (pic unrelated).

    Lack of 16:10 options is DEPRESSING

    AFAIK the RTings input lag numbers are accurate: https://www.rtings.com/tv/reviews/lg/cx-oled#page-test-results They use a custom board with a photodiode and synced output so they can capture the average lag on all parts of the screen. https://www.rtings.com/monitor/tests/inputs/input-lag The...

    Lack of 16:10 options is DEPRESSING

    CRTs do have on the order of nanoseconds of processing lag, because they don't really do any processing. That's not to say that the signal is going from your PC to the screen at that speed - that's still limited by the refresh rate and display timings. Which is I think where people get the whole...

    HP D8911 19" CRT losing red in integrated VGA cable (bad contact?)

    Yeah if it's not broke don't fix it... easy mode. The ferrite choke on the VGA blocks some EMI and the enclosure provides a convenient ground. The flyback transformer is where the anode cable runs back to: http://www.angelfire.com/oh3/ebjoew/Flyback.html You can see that there are caps in there too.

    HP D8911 19" CRT losing red in integrated VGA cable (bad contact?)

    Look, honestly you should go on badcaps or something like that where people have worked on hundreds of CRTs and could tell you off the bat what the issue is without a doubt. For general purpose CRT repair they have the knowledge. Logically it is probably a bad conductor in the cable. The high...

    Soooooo, anyone now considering an 8K TV after the 3090 DLSS demo?

    PPI of the 88" ZX is 100, the 77" is 110. That's the same as 1920x1080 at 22" or 20" respectively. You can be at 3 or 2' away and it will look like a personal IMAX. The 88" is $30k and the 77" is 20k. I'm sure some people have made that much just off of stocks during this big crisis.

    Help with Sony GDM FW900 - Ghosting like trail effect

    Yeah the whole thing is apparently anodized aluminum. Was "only" around $11,000 back in the day. I wonder if there are any in the US hidden in some old rich person's estate.

    Help with Sony GDM FW900 - Ghosting like trail effect

    If you calibrate the tube to a super dark black level things like bright white lamps and other objects in dark scenes will trail visibly.
