This is just like the modern projector market today! There are so many cheap projectors that claim to be 1080p because they can accept a 1080p signal, but are in reality somewhere between 160p to 960p depending on how cheap and crappy it is.

Even if a cheap projector has an actual 1080p chip it will still look bad because they use cheap plastic lenses. A genuinely good 1080p projector with a precision glass lens will produce significantly better detail than a cheap 4k one. Never judge a projector based on specs.

@Cowclops I got a $30,000 Barco 1080p projector with a $9,000 precision lens for $1,000 on eBay. 10,000 lumens and it's noticeably better than my $5,000 4k JVC. DLP doesn't degrade and it looks amazing. It's a way better tech than LCOS or LCD. I've learned that you can not have high contrast without high brightness. And most projectors that claim high contrast are simply dim and sacrifice shadow detail for blacks (you can't actually use). Now Oled is in a league of it's own. Once they make an affordable 150" oled I'll never use a projector again.

I worked for RS for almost 6 years, ending my career as a store manager in Pacific Beach, California. It was during the high point in computer sales. I could see the competition building & our quality dropping, so I went to seek my fortune in other ways. I, like you loved Tandy products. But by the 1990's there was little left to love.

But have no doubt when the Sensation 1 came out there was nothing else like it. RS had invented something they thought they could control.

Another fun Tandy 1000 RLX fact! The 40MB hard drive it came with is the Seagate ST351A/X - the last stepper motor hard drive ever made, and the largest 8-bit IDE drive ever made. To save cost, the drive also stored its internal BIOS on the platters themselves, and setting the jumpers wrong wipes the BIOS out, bricking the drive permanently. Working ones can fetch a pretty penny online (lots of dead ones available, though).

I hated this limitation. I filled up the 40MB drive quickly, and found I could not upgrade. The limitation had to do with the Tandy 1000 RLX being what I called a "fake AT". Prior to the AT, PC and XT motherboards did not support hard drives without an add-on controller, which provided its own BIOS. IDE drives did not require a BIOS, as AT computers had IDE support in the BIOS on their MBs. The RLX 1000 did not have BIOS support for IDE drives. But Seagate made two IDE drives with onboard BIOS, a 20 MB version and a 40 MB version. That was something else that made these computers and hard drives unique.

It's really not Tandy being cheap, it's people being cheap. They liked Tandy machines because they were cheap. That cheapness came at a cost. That cost was Tandy computers were junk and they were non-standard. The positives that you see with Tandy machines is because the machines were close to 10 years newer than a 5150. It's easy to forget that by the time the T1000s were selling really really well, the PC was already years old. They were generally lower speced than any other PC on the market other than other 5150 clones.

I most certainly remember flipping through PC catalogs back in the day, and them listing the various monitors they had available, along with their dot pitch. I learned early on about dot pitch and how a smaller dot pitch yielded a much higher quality image. My experience was with the IBM PS/2 line of monitors, I had an 8512 which had a .41 dot pitch, but was a 14" monitor. I also had an 8513, and while that was a smaller monitor at only 12", it had a .28 dot pitch. Much higher quality image. Nevertheless, I ran the 8512 for years, most notably connected to an IBM PC/AT 8MHz model with VGA graphics. And my findings were exactly the same as yours, horrible for Windows and most things, but acceptable for DOS games, which I spent a lot of time playing back then. Dot pitch really made a difference for more demanding stuff at higher resolutions. Even as time marched on and I started working on PCs, I could tell who knew what they were buying based on their monitor. I also can't even tell you how many people were running their Super VGA monitors at a low resolution at only 60Hz, usually with their monitor on the tilt/swivel stand pointing as high up as it could. I set a few of those people straight and they would often comment when they saw me again how much better their monitor was since I "fixed" it.

I feel like this is one of your best videos, and I know you have made quite a few. Such an interesting part of history - selecting a new monitor and zeroing in on the dot pitch. It was price vs. dot pitch after selecting screen size once upgrades started for me. My first VGA monitor was a Cordata - likely cheap with terrible specs as I just wanted VGA at the time. I think I may have stashed it in my parents attic a few decades back - it is probably still there. I moved to ViewSonic monitors in 1992 and always tried to keep new stuff at or below .28. Seriously - great job. Thank you for your hard work putting this together and taking the time to dial-in your camera on that CRT.

Modern GPUs often come from the factory quite a bit bigger and beefier than they need to be. My 3050 while being a dual slot card, could easily be half the size it is and the card never goes above 50c ever. They have to get to around 100c for temps to start throttling the GPU. So many cards today are overbuilt to look more impressive than they actually need to be.

One big blunder Radio Shack did was when they changed suppliers for their plastic electronics project boxes. The new boxes had new dimensions, which didn't fit any of their prototyping PCBs, the designs for which hadn't been changed since the 60's and 70's. The screw post positions didn't match and for the boxes that had slots to put a board in sideways, the boards were too long or too short to fit across the boxes.

I can relate to this, we used a CRT display until as late as 2011 (I think?) and for some reason I thought it was cool to run it at high resolutions, which can make pretty much any monitor look like this. After a while you get pretty good at making out the text, but it was far from ideal. Pretty nostalgic though, really makes me appreciate the 1080p and 4k displays in modern devices. Funny thing is, people are trying to emulate this look on modern screens these days.

Wow, that is remarkable. They must have had a surplus of tubes designed for CGA monitors, or perhaps television sets. That's like that 5" Radio Shack Portavision I used to have, that had 80 "pixels" going across. Nauseating to look at up close. But I'd be lying if I said I didn't find this monitor kind of endearing in a world of Trinitrons and ViewSonics. Does it accept any SVGA resolutions? For what it's worth, while the phosphor dots on a CRT can be equated to pixels for calculating the effective horizontal resolution, it can't for vertical resolution, as it's actually possible for just a portion of each dot to be illuminated. They would actually be solid vertical lines (and they are on a Trinitron), if it weren't for the shadow mask getting in the way. So it may be limited to rendering 484 pixels horizontally, but it's a much higher number vertically, limited by the quality of the signal and monitor electronics.

I would say horizontal resolution could still take advantage of partial dots, but not as much as the vertical.

A better way to put this is that the effective resolution for luminance is greater than that of chrominance.

Yes, there are gaps between phosphors in that direction, but they're only small (compared to the ~80% gaps for the horizontal direction). Vertical resolution is more determined by the three electron beams' focus and convergence. You would obtain better (horizontal) resolution by increasing the scanning width (and obviously height to maintain aspect ratio) of the raster. Note that the "digital" pixels won't generally necessarily line up exactly with the "analog" phosphors. In fact, they''ll never perfectly line up due to imperfect deflection linearity. Assuming, here, that you have access to width and position controls (probably internal settings for this set). You will always obvserve a moiré pattern if the video bandwidth and focus is up to it. They may choose to defocus the beam(s) slightly to avoid excessive moiré. This comment may be of interest to the retro computer scene...

Same thing happened on the CoCo 3 realm. Tandy offered the CM-8 monitor which was RGB Analog to match the hi-res output of the CoCo 3. Problem is the 0.52 dot pitch of the CM-8: horrible for the hi-res text at 80x24 and more so at graphics 640x192. Magnavox had the BEST option for many CoCo enthusiasts with the 8CM515, a 0.42 dot pitch monitor that not only could take RGBA but also RGB digital an do base-band video, even had a switch to turn the composite video in to all green - on the 1989 catalog the CM-8 was $100.00 more expensive than the CoCo 3, itself going for $199.95; buying with third parties you could get the Magnavox for around $260.00

Interesting that this uses the slot mask style shadow mask (instead of the dot mask pattern much more common in later VGA monitors). I know that slot mask was the norm in TVs by this point, but it could be a contributing factor to the horrible dot pitch on this monitor. Heck, the CRT used in this could have been shared with 13" Samsung TVs to help bring down the cost.

484 x 425... Well, going back to TV frequencies and CGA for a moment, when 484 is divided by 160, it is 3.025. Basically, three color groupings per pixel. When CGA was run in artifact color mode over composite video, the effective horizontal resolution is 160 pixels. The Tandy 16 color CGA capability was 160 pixels too. TV signals, when the colorburst is run in full alternating phase, alternating line mode, one gets 320 pixels of color, all lined up nicely with the NTSC color burst. That CRT, with the horizontal size lined up just right, would deliver a bright and clear TV image. In computer graphics, it is good to about 320 pixels before subtle mismatches between the graphics pixels and the phosphor pattern on the CRT glass. Above that, and pixels look different depending on where they are lined up, and the one exception would be to run a non standard resolution to line it all up one for one. I would totally put money down on those CRT tubes were for consumer TV use, and were just overdriven for VGA. One other interesting bit might be worth a mention here: next comment due to me being on mobile...

I see this dot pitch on some TV / VCR combos. VHS divides the color signal by two when recording. Commercial units did not do that, and that is why purchased pre recorded movies looked better. The players could play a full color signal, but not record it. Home recordings were basically 160 pixels of color interlaced, and that tube matches VHS play back of home recordings. It would actually make them look a little sharper due to the tube size and the nice match up of the "pixels" coming off the tape nicely quantizing everything which implies some resolution that is not there otherwise. I have one and it looks great when used with TV type graphics signals. An Apple 2, or Atari, VHS VCR, MSDOS as the video mentions, all will be just fine. Last nerdery from me on this, and it is all about brightness. Low dot pitch CRT tubes can deliver a brighter picture, in general. They got used in arcade cabinets and that is what I plan on doing with mine. The tube is a great match for early games I like, and mine is super low hour. Basically was new in box, opened and used a few times and that's it. Should be perfect for a cabinet able to deliver the bright images typical for the time.

@@DougDingus Fascinating about consumer VHS VCR's only able to record half the resolution of the color signal. It makes a bit of sense, as I do remember pre recorded studio movies always looked better than any recording you could do yourself on the same VCR you played that movie on, even if you had a clean source. I always thought it was more to do with the pre recorded content coming from a a high resolution professional equipment with 1st gen copy being played with a better signal to noise ratio onto the VHS tape. However, maybe the other aspect was the color information was full bandwidth being recorded to the tape as well. Color burst information was about 1.5 MHz across. But VHS played tricks and took the color information and recorded it below the video bandwidth in the 630kHz range. I believe this was done to to account for variations in head speed and tape speed that was not always stable, something like a 0.1% difference in speed could shift a single color scan line from red to magenta. By shifting the color burst information to a lower frequency the variation in speed has less effect on the phase it would seem. They also did a phase averaging of the color information that was split between two fields doing what seems similar to how PAL dealt with color phase issues but with half the 1.5Mhz signal in one field and the other half (750KHz bandwidth) in the next field. Then recombining the two halves when everything was upconverted back to what the TV would recognize as a standard color subcarrier. Maybe when you recorded on the consumer VCR they only recorded 750KHz of the full 1.5Mhz of the color subcarrier onto the tape using simplified circuity, whereas the professional VHS machines would have the extra circuity to deal with splitting the 1.5MHz color subcarrier between the two fields. It must have taken a much more precise filtering network if they wanted to record the full color bandwidth. Professional U-matic tape machines recorded composite video with the color subcarrier left where it was originally generated at 3.58MHz (NTSC), however the U-matic 3/4" VTR had much more precise tape and head speed control and thus could keep the color from shifting hue. So they didn't have to play the game of shifting the color subcarrier below the luminance video information like they did on VHS. Of course this was back in the early 70's, so maybe filtering technology they would have needed was not up to par then in a tape machine within reason. So they just made the head drum speed and tape travel speed much more precise.

I lucked out and got a nice Mitsubishi VGA monitor that was being scrapped at work because it had some case damage. The difference was like night and day. Monitors and PCs were so expensive back then, especially when adjusted for inflation that a lot of people ended up with sub par equipment because of these cost cutting tactics.

Phosphor dots are NOT pixels!!! Technology connections did a whole set of super long videos about this. The key here is that phosphor dots need not be uniformly lit. Pixels are always uniform. A coarse dot pitch does give that "looking through a screen door" effect, but the "holes" are not a single solid color like a pixel would be. Yes, coarse dot pitch sucks, but it's not the same as downscaling the image to a lower pixel resolution.

CRTs don't have physical pixels, they only exist in the source's frame buffer before being converted to an analog video signal. The electron guns paint rows of pixels from left to right and top to bottom. The image on a CRT is an analog representation of the digital frame buffer. Dot pitch only affects a CRT's color resolution, not the vertical raster resolution which is an effect of beam spot size, focus, and horizontal scan rate. This is why monochrome CRTs are much sharper than color CRTs when running at the same raster resolution.

Also 484x425 is the maximum resolvable resolution, meaning that only 484 pixels per scanline, and 425 scanlines, can be displayed without overlapping (or sharing phosphors). 640x480 is still being displayed regardless of the CRT's coarse dot pitch and low TVL count, it just looks blurry due to the overlapping pixels and scanlines.

Oh wow, this is one disappointing monitor, I’m really shocked they thought this was okay! Especially considering they were marketing it as “crystal-clear VGA.” The font examples you used were really shocking, I can’t believe they let that happen! CRT dot pitch is such a fascinating phenomena, the computer produces a 640x480 pixelated image then it’s sent to the tube where it just scans 480 lines across the screen with 640 horizontal samples, which is then basically intercepted by a screen door to provide the colour, I wouldn’t refer to the triads of colour phosphors as pixels but the resolution can be really limited by the dot pitch, there’s no actual scaling but the detail is seriously smudged and blurred. My VGA monitor is an old dell from the 90s, the dot pitch is more than good enough for the low resolutions I run it at (640x480 and 800x600 usually) but it looks great even at 1024x768, I honestly think the way the dot pitch effects the image is so fascinating, it looks ever so slightly softened and rounded in a really nice way, I was playing a low res old visual novel a while ago and at its native 800x600 resolution it looked great on my CRT, the pixelated artwork was rounded out by the dot pitch and it made it look way higher quality and so smooth and nice.

I remember how awful this monitor was! But remember the CM-5 from the 80s? Wretched! And I totally got chills when you pointed out the 17kb cost of that VGA utility. Remember when that was a big deal?! lol. Thanks for the nostalgia, friend.

While horizontal resolution is affected greatly by dot pitch vertical resolution is largely irrelevant when the phosphors are arranged in stripes as the electron gun doesn't illuminate the entire phosphor group every scan line.
@CoolerQ
@CoolerQ 2 жыл бұрын
Dot pitch can't be converted into DPI as simply as you showed in this video, unfortunately. Multiple "pixels" can actually be shown in a single dot - each phosphor dot is not necessarily illuminated evenly. But it definitely still looks like poo on a color monitor when the video resolution exceeds the dot pitch.

Yeah, you clearly haven’t used any of the old school LCD monitors from the mid 90s up until maybe about the mid to late 2000s. Comparing this to nearly any one of those, this might as well be 4K. Even when Apple did it in the iMac G4, it was super dim, low res, and disproportionately lit.

They were sharp, though. Awful in every respect, but still clear, readable text so at least you could be productive with it. A lot of earlier "high res" LCD monitors did seem to have a lot of bleed between pixels though, I guess just how they were driven I dunno, and those would've been hell to use for work.

Tube looks like a slot mask. Appears they cut costs by just plopping a low end TV grade CRT into that and called it a computer monitor? lol I wonder what model of TV that tube could be found in. I'm sure they reused existing stock or something.

That's a CRT used in Samsung TVs. For TV that's enough. The NTSC video signal doesn't do more than 350 distinguishable vertical lines of analog video. And 525 horizontal ntsc scan lines had 480 usable ones and with over scan there you have the 425. And don't forget - VGA is NTSC with twice the scan line frequently, making it 59.96p without interlace.

I remember seeing a .45 Goldstar monitor in the early 90s next to a Sony Trinitron at .28, the difference was night and day. Both were running a VGA 640x480 input signal, after that I only ever used Sony CRT monitors until LCD came along.

I just configured a 486 computer, which is right next to me as I watch this video. It is an IPC Dynasty (not exactly because I changed the motherboard, but the 14'' monitor is), and I can tell you that it is WAY better than the Tandy you are reviewing. I was kinda impressed by the image quality, except from the lost space on the X axis (there is a Y adjustment potentiometer). The part number is VDVGA 14#60, I was not able to find something online.

When I had a VGA in the 90s, I could adjust the image, to minimise the black borders on the edge of the screen, I think you would get a slightly better view that way. My monitor had dials for width and position. and height and position. I had a video card, later, where the timings of the signal to the monitor could be well fine tuned, and I made a custom resolution of something like 1024 x 512 for watching video, I had a dvd drive. I squeezed down the image so the black bar space in the image was not processed, so all the compute in the system was used for the part of the monitor that had an illuminated image on it. Then switched the resolution back to 800 x 600 for normal windows programs and expanded the vertical back to normal. Monitors sure have come along way since those CRTs.
