The worst VGA monitor ever made - Tandy VGM-225

The monitor that was so bad, it may have led to Tandy's downfall as a computer manufacturer. Built for Tandy by Samsung, the VGM-225 (and almost identical VGM-220) has a very grainy image due to the coarse 0.52 mm dot pitch of its picture tube. It's OK for most games, but not for reading fine text.

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.

[@jamesw.1174]

How true, how true. Walmart had an RCA projector for like $50. I was curious so I bought one and it wasn't bad but it wasn't good either and it was nowhere near HD resolution.

[@Zebra66]

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.

[@mattcintosh2]

I worked with a computer recycler and used business projectors werent worth enough to bother reselling. I brought home a Dell DLP that looks decent, think it does at least 1080p, but only worth maybe $60

[@Cowclops]

@@Zebra66 exactly. I’ve switched to a 77 oled for my home movie viewing but I still have and use my Panasonic ae4000 from 2011. Sharp 1080p with pretty good contrast and color reproduction means it’s still usable today. Infinitely better than the $100 microprojectors.

[@Zebra66]

@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. Except for the Sensation. To little to late as the saying goes. You definitely called this product correctly. Good job!

Tandy was really amazing during their high point. In a lot of small towns, Radio Shack was the only computer store. I remember saving up for a Sensation, but I ended up with a Compaq Presario by the time I had enough money saved.

Did a little googling, and the Sensation was way overpriced, given what that $2200 got you. Maybe $1,000. By 1995 I was running a 486dx2-66 with 8Mb ram homebuilt that I spent a lot less than $2200 building.

[@HavocSun]

@@Caseytify It's difficult to get the timing right when you research the Sensation. Actually RS tried to piggyback off the success from the Sensation 1, by making 2 upgraded versions. By that time RS was betrayed by Microsoft. And the end was near. It's a complicated story. Maybe I will do a video on just what happened. 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. The Sensation was the first ever Muti Media computer & sold out every unit made in less then 3 months.

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).

[@magmajctaz1405]

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.

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 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.

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.

[@themaritimegirl]

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.

[@vwestlife]

It only supports standard VGA resolutions up to 640x480 at 60 Hz, or 720x400 at 70 Hz.

[@MrDuncl]

My first thought was "its a TV tube". Not surplus but cheap because they were being made by the million.

[@eDoc2020]

I would say horizontal resolution could still take advantage of partial dots, but not as much as the vertical. Today we might call it subpixel rendering and it's fairly similar to a Bayer filter in cameras. A better way to put this is that the effective resolution for luminance is greater than that of chrominance.

[@justanotheryoutubechannel]

@@eDoc2020 I had the same thought, it definitely does take advantage of it partially but it doesn’t look great, it’s like a semi-transparent screen door is covering the image in a foggy room, it kinda blooms out and fills the gaps but it’s not good looking.

[@PascalGienger]

@@MrDuncl Exactly my thoughts. TV over aerial antenna and cable had around 300-350 lines (the "pixels" (there are no pixels on an analog medium) VWestlife counted horizontally). VHS tapes had 220-240. 170 in extended play. Laserdisc had 350-400. Vertically you'll always get all the lines sharp as the electron beam keeps it correctly at the correct "height" while sweeping the line of picture and only that part of the phosphor glows up

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.

[@davidbeard7262]

Vertical resolution doesn't work that way for this CRT; the phosphors are basically continuous in the vertical dimension. You can display many scan lines across a single vertical stripe. 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...

[@rfmerrill]

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.

[@primus711]

The convergence being off definitely isnt helping it either which you can see easily on your close up while booting

[@reddragon27284]

If the monitor doesn't have external controls for it, maybe it has internal adjustments but I would have thought you might be able to improve image quality at least a little by adjusting the vertical and horizontal size to reduce the size of those borders and that would allow more "dots" per pixel. Might only be a slight improvement but would be interesting to see.

[@SandTurtle]

yeah expanding the image would make it clearer, but you would lose some detail to overscan

[@probnotstech]

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.

[@DougDingus]

My thought exactly. That resolution / dot pitch would perform reasonably for television viewing. And CGA was done at TV frequencies too.

[@DougDingus]

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.

[@marcusdamberger]

@@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.

[@MagnumForce51]

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.

[@darksoulzfreak]

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.

[@darksoulzfreak]

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.

[@RogelioPerea]

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

The experience is a bit like using one of those VGA to composite TV adapters and sitting too close to the TV.

[@snaredude56]

My first PC was a slightly used Laser 386sx with an equally crappy 0.52 dot pitch monitor. It was as bad if not worse than that Tandy monitor. It was so bad that I figured it had to have a problem with the focus so I pulled the back and adjusted it. It didn't help at all. 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. I had a double whammy because in addition to the terrible monitor I had the sx processor. Good times.

[@MrDuncl]

[@CoolerQ]

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.

This channel is really Time Travel for technology I don't ever ever ever want to see again. I was so glad when LCD flat screens replaced the CRT in monitors and TVs.

High quality CRTs still have their uses, but generally I can agree. I once owned a rather cheap 15" CRT that, for some reason, supported 1280 x 1024 but the dot pitch was so bad that anything below about 14 pt font, any font, was completely unreadable.

Lets praise the early adopters who spent £500+ on a 15" LCD and then put up with dead pixels which the manufacturers claimed were normal.

Although that really is a low dot pitch for a monitor it also seems to be way out of focus, probably done intentionally as an attempt to make it less noticeable and that's the real reason why it is so blurry and unreadable. I remember being able to read text at 640x480 on my tv screen using s-video but not on composite, i'm sure my old TV's dot pitch was lower than of that monitor and VGA is a better signal.

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.
