Sega CDX RGB output without modding???

I used the wrong words, instead of component I meant composite, the yellow RCA cable video.

I recently upgraded all my more modern machines to S-video and while I did see an improvement it was pretty minor. My Genesis is stuck with typical RCA cables (yellow for video, red and white for audio) and it sure looks great to me though I can't say I've compared side by side with RGB. But spending multiple times for RGB capability (even if you already have a monitor which can support it) than you would on the console itself seems extreme. But then I don't have a TV that can do anything more fancy than S-video anyway.

Oh you'll see a huge difference between generic composite (RCA R/W/Y) and RGB.

scroll half way down the screen here:

to see a side by side comparison.

Also RGB cables really aren't that costly. I got mine for about 4 to 10 quid a piece depending the console (ordered em' out of Britain, shipping wasn't bad either).

then again that might seem like a lot to some. But when I rock a 50 inch 1080p DLP screen with a massive sound system cranking out of a Marantz SR7001 receiver... well 10 quid ain't much for a boost!

... you should hear my neighbors cry. heh. You would too if you heard "Foetus" blasting through your neighbors wall.

Thanx "lordofduct". You have lived up to your reputation because I barely understood all that high tech vocabulary you just used up there. :P Kidding. I have learned something new today, thank you.

I don't know if my Sony 17" LCD HDTV/monitor falls into the cheap or expensive TV, but it cost me 500 dollars two years ago and it does have progressive scan. It's native resolution is 720p. I don't know if it is any good, but it is good enough for me.

Anyway, I have just made an order for the XRGB-2 plus so it is too late to change my mind. The only negative thing about it is that it does not support progressive scan.

There are a couple of things that I want to use it for:

-First, to make the pictures for my 16 and 32-bit systems look as best as possible.

-Second, to eliminate or reduce picture lag because my monitor/hdtv has a 16ms response rate and doesn't do well with some movies and games. I think this happens because the TV has to upconvert all non HD source, i.e. some DVD movies and PS2 games. (Please confirm this if possible.)

-Third, to make the game systems output the game in true low res on my hdtv/monitor. (Is this even possible???)

Sorry for being so ignorant about all this stuff. I will admit I am a bit of a graphic whore and I just want to see all my pre-HD games as beautiful as possible. :P

Firstly the progressive scan thing with the XRGB-2 is with input... not output. It takes only interlaced RGB signals on input to output the VGA. The upscanning will cause a minor amount of delay.

topic 1: it will do this
topic 2: actually more lag could possibly occur on your LCD panel. It is inherent in the analog to digital conversion, the slow response time of LCD, and the scaling (seeing as the XRGB-2 does not output 720p, it will have to scale it).
topic 3:this is not possible, LCD is a native resolution only kind of display. The resolution it says it does, is the ONLY resolution it does. It has a scaler built in to deal with any resolutions that aren't the native resolution.

Also the XRGB-2 will not put out the native resolution of your console either. The genesis is a very low resolution of:
256x224 (32Hx28V), 320x224 (40Hx28V), 256x240 (32Hx30V, PAL only), 320x240 (40Hx30V, PAL only)

the XRGB-2 will upscale these to either:
640X480 at ~31hz
1024X768 at ~ 47hz

to get your monitor/tv to display it at these resolutions, you need a display that supports a resolution range (isn't a fixed-pixel-display). CRT to is really the only consumer product that isn't a fixed-pixel-display.

Last question before I let this topic die and go into a corner and start crying. :(

In your opinion, was it a really dumb move to spend all that money on the XRGB-2 Plus???

Your previous answers have made me feel like I have made a mistake, a huge $200+ mistake. :shock: Of course I haven't seen the results of XRGB-2 Plus and what kind of improvements it makes with my own eyes yet, so I don't know if it is really worth it or not.

you will see improvements... no doubt about it. You would see even more though if you hook it up to a CRT monitor.

When you use it, make sure you output the 1024X768. That is the closest to the native resolution of your LCD, so it will have the least distortion. Also if you display supports it, display it in 4:3 mode... not 16:9

I read from some people that the picture won't be as good with 1024X768 as it is with the 640X480 when using the xrgb-2 plus. BTW, what is this distortion you speak of??? Guess I wouldn't understand until I have the xrgb-2 plus in my hand. Anyway, thanx for helping me become such an informative buyer, though I don't know if that is a good thing or not. The more I know, the more stupid I feel. HA HA HA. Later.

Your scaling a 4:3 image (square TV) to a widescreen monitor (720p is wide screen). The image gets stretched.

Really you can set the XRGB-2 to either of the settings, because in the end it all gets scaled to 720p. Just play with all the different combinations and decide which looks best to you. All in all, you should notice a much better picture then composite.
