    4K HD TV COMPATIBILITY WITH XRGB MINI AND RETRO SYSTEMS

    Hello all,

    I'm in the market for a new tv and currently considering a 4k hd but I'm unsure if it works the framemeister. Any body know if the framemeister works with 4k tv's? How does the scan lines look and any lags compare to the 1080 tv sets?

    Thanks

    I don't have any first-hand experience, but I assume that a 4K TV will have to quadruple-upscale the 1080p signal that from the Framemeister, resulting in chunky pixels and lag. Maybe you should wait until a next-gen native 4K upscalar comes out?

    I'm using xrgb mini with 4K projector without any problems. Scanlines look good and lag is no worse than with full hd tv. Picture is better than with my 1080p projector

    I've got one hooked up to 4k and like it just fine.

    I don't have a solid way to test lag but as far as I can tell it is not an issue for any of the games I've played. The scan lines though will be the same issue as always.

    I guess some of the issues will depend on the actual TV. I hear some have crappy upconverter/scalers or whatever and do produce a good bit of lag.

    Those scan lines looks great but I know the framemeister only displays the scan lines correctly on 720p. So am I suppose to look for a 4k tv that have the option down scale to 720? I know the scan lines looks terrible on 1080p.

    I'm assuming the scan lines only looks good on 720p? Is there an option on your tv to change the output to 720p instead of 4k?

    3 * 720p = 2160p = 4K resolution. 720p material scales perfectly fine to 4K and scanlines scales like anything else in the picture. Scanlines looks crappy if you use 1080p resolution in xrgb, because it first scales and the applies scanlines and with 1080p scanlines are too thin compared to the actual pixels.

    That is pretty much how it works out. Set your mini output to 720p and use your scanlines and let the tv do the rest. I've tried it with and without. Both options look good I think. I'll see if I can get some pictures up later

    I also can't see any reason why a 4k TV will have issues providing the converter is outputting in in one of the standard resolutions accepted by panels.

    My camera won't play well with the tv. I can't take a full screen shot and it look decent. Maybe its the lighting.

    Here are a few pictures that came out okay. They are just some close ups to show the scanlines on and on with them off.

    My lag test is being able to grab a star card in SMB3. Lag will get you a flower card every time.

    That looks pretty good, and good to know the scan lines scales with the pictures. Thank you for sharing dude.

    My lag test is fighting Soda Popinski in NES punch out, if there's lag I can't beat him, or I barely win and get slaughtered by Mr Sandman. On a real NES on a crt I can beat it easily, including Tyson.

    My lag test is surviving Contra or Metal Slug. With lag, it's pretty impossible
