--- Quote ---Note: 1、Some traditional CTR display not work after connected witch this Converter This mainly caused by these Displays only supporting 480i and 576i YPbPr interlaced resolution. Therefore, we suggest to choose LCD Display or those can support YPbPr CRT Displays. 2、Some connected Displays may have no image after setting the resolution of HDMI source at 1080P.This not caused by our products but YPbPr channel of Displays not supporting resolution at 1080P.
Support HDMI input resolution: 30Hz 1080p/60Hz,1080i/60Hz, 720p/60Hz, 576p/60Hz, 576i/60Hz, 480p/60Hz, 480i/60Hz; Support Ypbpr component output: 1080p/60Hz, 1080i/60Hz, 720P/60Hz, 720i/60Hz, 480p/60Hz, 480i/60Hz. Supports165MHz/1.65Gbps per channel (6.75Gbps all channel) bandwidth for HDMI Input

in a nutshell, this TV is going to be a PITA to get a decent pic displayed and even then, it's not going to be great since it ONLY supports 480i. I would look into soft15k and RGB modding the TV to accept straight RGB input which you can scab right out of the VGA DB15 connector. I would just ignore HDMI since it contains purely digital signals that need to be converted to analog to run on your TV anyways.

You've got good advice going on here from the folks above. I would second newmanfamilyvlogs that you should highly consider reading up on GroovyMame. CRT Emudriver modifies the drivers of your ATI/AMD graphics card to allow it send signals below 480p (31khz). As lilshawn said the graphics cards don't really want to go below 480p as that was the standard for computers.
You can get a good signal to the TV, you will have a couple of hurdles though.
1.) With Component input (PyPbPr) you can't simply connect the VGA to Component cable. You will have to do a conversion via a Transcoder.
2.) You can as lilshawn suggested RGB modify the TV to accept a direct RGB signal (one that comes from your computer).
Problems with 1.) is that Transcoders that don't scale or convert the signal aren't that easy to come by (expensive too).
Problems with 2.) is that RGB modifying a TV requires a decent amount of knowledge of CRT's and comfort with soldering and potentially looking up schematics.
I bought my transcoder off of a guy that was putting them together on e-bay, but he appears to not be selling them anymore.
Here is one I found that may work, although you would definitely want to confirm with them that it doesn't do any scaling, just transcoding.
As for RGB modifying the TV, there is a great resource for doing so on the Schumps Forum here . I would also suggest doing a YouTube search for RGB modifying a TV into YouTube to get a sense of what it entails.
Lastly, as that appears to be a Sony Trinitron clone (use of aperture grille), there may be challenges in getting signals below 59Hz. At least that was the experience of myself and a number of others in using Sony's flat panel CRT's. A number of original arcade titles used refresh rates below 59hz, and you have to accept some compromises. Sylvania could be using a different chassis on the TV making this a none issue.

Are there any specific CRT TVs that would be better suited for this application. I pulled this one from a recycling area at the dump and was hoping to repurpose it. I can always scour local classifieds, craigslist or pawn shops if there is a better option.
OR
Is it easier to get the desired resolution from an LCD or LED display? Those things are becoming a dime a dozen as well.

The one you have is fine, you just either need to spend money on the Transcoder, or spend some time researching the RGB mod (there are a lot of examples on the link I provided, and YouTube shows a lot of people that have done it).
The only plug and play CRT experience we have here is Arcade monitors, which are harder to come by (at least in my area).
There was mention of changing the output signal from the graphics cards from RGB to Component (PyPbPr), but I hadn't seen anything definitively that there were examples of people doing it.
Don't go the LCD route, we need to keep the CRT's alive, and they look and perform a lot better.

Thanks Arroyo! I'll watch the videos and see if I can't modify the TV. I did some work with the WG chassis on my original unit and felt comfortable working with the components. I will definitely need a new soldering iron though!
