I have several CRT VGA monitors. I like them better than LCD displays, as CRTs usually have a wider color gamut. Usually twice the gamut "area" on that sharkfin pattern.
Using a larger VGA CRT for a HDTV display: It's fed by an RCA DirecTV ATSC and satellite box, which works on ATSC without a satellite subscription.

I used to have one of those Gateway Destination 36" CRT VGA monitors in my basement. It could only do 800x600, but I loved it. I loved to play emulator games on it with a PC. I also liked to watch TV and movies on it with an external tuner box. I sold it to a friend when I moved into a smaller house.
Last I knew, my friend still uses it as his bedroom tv. I moved again recently into a larger house. I just might have to get that monitor back... I need a garage TV

I have several PC CRT monitors that are capable of various V&H scan rates. They are capable of up to a 180 Hz refresh rate. I was hoping to use one for a CBS sequential color monitor requiring H=29160 and V=144.
The problem is that they all seem top be "programmed" to lock only to specific combinations of standard scan frequencies. How does one unlock the programming to allow this oddball H=29160 and V=144 scan combination? Thanks for any help. Cliff

I have a Hewlett-Packard mx70 monitor I use with my PC. It had a great image when it was new some five years ago (more or less), but about a month ago I noticed the raster was bending rather severely, as if the auto-degausser had quit. I tried everything I could think of to restore the raster to its proper size and shape -- pincushion adjustments, centering, positioning, you name it (this monitor has quite a few adjustments for raster parameters such as pincushion, pin balance, etc. in a menu called "advanced geometry") -- but, try as I might and did, I couldn't get it right, and I fiddled with the thing for days.
I was about ready to throw in the towel and get a new flat-panel monitor. As I write this, however, three weeks or so later, the problem seems to have corrected itself, as now the raster is 99.9 percent straight (still some very slight curvature, hardly noticeable, at the extreme right side of the screen). What could have caused this problem, and why did it go away on its own?  I thought these problems only got worse with time, until the monitor either went up in smoke or the raster was so distorted as to be completely unusable.BTW, I wonder if the MX70's pincushion correction is digital. As there are no potentiometers for setting brightness, contrast, etc. (as I said, everything on this monitor is controlled through software; all adjustments are made via menu selections and bar-graph controls, activated by "select" and +/- buttons on the monitor's front panel), I would think the mx70 is at least partially digital.

I finally solved it when I was in the next cubicle over, to work on that PC. When I turned on the monitor, she yelled "there it did it!". Here it was the degaussing coil in the next cubicle interfering with hers when the person in the next cubicle turned on their monitor in the morning. Their monitors were back to back, with the cubicle wall between them. LOL

The only CRT monitors I'm saving are the 14" TTL amber that came with the original IBM XT, (Plus the PC itself) An EGA 9-pin 9" Electrohome, and a 22" Sony with DVI.

I had a VGA CRT monitor for my old Dell computer from 13 years ago. When I bought the computer that I am using now (Compaq) a few years ago it came with an LCD monitor.
About 2 months ago I tried to use my old CRT monitor with my new computer just to see what it looked like. It had a very nice picture. But after a few uses with my new computer the CRT monitor broke. My guess is that such an old monitor couldn't keep up with the speed of the new computer. I threw the monitor away. Oh, well! Last edited by basil lambri; 08-18-2011 at 09:33 PM.

There's a Thrift Store near me that always has a rack full of CRT Monitors, everything from an E-Machines to Sony, most still work and most are $5.00. They generally aren't terribly old, mid 90's and up. If I had room I'd grab a nice 21" model just to have. I had a Sony but got rid of it when I got this HP LCD, so much space saved on the desk by doing that! I do still have a 15" Sony that I got new about 10 years ago, it works but the CRT seems to be getting old, it's not as sharp and bright as it used to be (but neither am I)

There was a 14" and I believe a 9" Sony Trinitron monitor that was produced around the late 80's. It was VGA and would do 800x600 interlaced. They were cool and I used to have one in my office connected to and old 386SX (Laser) was the make of the computer. You guys remember those, lol, believe it was an old Price Club branded computer. The Sony monitor however only had the EGA 9pin, but there was a converter cable that would connect it to a 15pin VGA. THe monitor also had the old VTR olive green connector too. It looked strangly similat to the 80's small professional broadcast monitors.
