For one thing there are millions of CRT and LCD monitors that cannot accept interlaced video, for which GSM can make the signal RGB, progressive scan, so they can be used for gaming. This avoids the need for a TV, when people already have a monitor.

Some rhythm games, and fighting games are unplayable with this lag.
GSM can feed the cheap upscaler a higher resolution (preferably close to the display's native resolution) to avoid these problems.
GSM can also compensate for scaling chips that don't properly handle certain aspect ratios correctly.
I am sharing here an idea that I had a long, long time ago - but I've never wrote here - for those NGOs* that work with poor communities.
GSM and cheap-homebrew VGA adaptors/cables, together with donated PS2 Consoles/Games/VGA Monitors, make easier to build game rooms into NGOs' youth corners, giving some fun for poor/street children/teenagers, keep them off the streets and criminality. This is just a single action among many others, but I believe it still worths!
my old 14" TV died on me and all i got is a PC as entertainment and thanks to this god send hombrew i can now again use my playstation 2 on my cheap LCD which is so much better than a TV capture card.
If you are looking for some program that can actually improve the resolution of existing game material. Adding in new well-designed pixels in addition to the pixels designed by the game developers, then you are searching in vain. No such program is possible.

Anything other than that would cause severe compatibility and speed problems. Attempting to use software filtering to 'enhance' the blockiness of magnified pixels would inevitably lower the gaming speed to some low fraction of the normal speed, making most games unplayable. So this is not something GSM aims to do, ever...
There are still several different purposes that the program can serve, as follows:
1: Switch between NTSC and PAL video mode, for both PS2 and PS1 games
2: Force any PS2 game or homebrew to work with a VGA screen
3: Force many PS2 games to use a progressive mode, completely eliminating interlace flicker
4: For all the above, as well as for unchanged video modes, allow recentering of the screen
There are some other variations too, but this should suffice as motivation, and if not then I suppose this is just not your kind of tool...

I see 100's of working CRT monitors being disposed of every month, simply because people want a thin LCD.

I have 7 extra working CRT monitors in my personal possession right now.
Hi everyone! First of all, I'll introduce myself, I'm from Spain, so sorry about any kind of "speaking mistake" (or should I say "writting mistake"? anyway...).
Then, I'd like to give my congratulations and my respect to everyone involved in this great project, really, you're awesome guys! And not only about GSM, but for everyone cool project that came from here.
I've read almost all the post in this tread, and as far as I know, I haven't seen anyone with a problem like mine, so let's see it...
Ok, I have an LCD tv/monitor, it supports progresive scan and all the shits, I have a pstwo with Free Mc Boot 1.8b, I use ERS too. Then, I downloaded GSM u beta. Then comes the problem. I ejecute the elf, I set GSM, and I go to the ps2 browser (of course, using the exit option of GSM), but once and once again I have the same ****in trouble. The display is something like "pixelated", just like the opposite of increasing resolution. In fact, is more like if the resolution were decreased.
I don't know what the hell is goin on on my pstwo...at first, I would have bet for some trouble with the tv and the way it treates the progresive scan...but it's not the cause of the matter...
Oh! I almost forgot it...of course I'm using the composite cable.
So, I'll be very gratefull if someone could help me. I hope not to take much of your time reading and thinking about my damned troubles...
Thanks for all, sorry about my shameful English and cheers!
I've tried HDSM Exploder hdtv, and it works perfectly. But I'd prefer using GMS, most of all for the ugly way HDSM has of rescaling.
Please read the firsts posts in order to get further details and better undestanding why your stuff goes pixelated (since there is no miracle) and how to improve your final results (use commercial or homebrew component/vga cable and/or adaptors).
I finally got my new Samsung (LN40B550) 40" 1080p LCD HDTV today, so I can do testing of GSM v0.23u on it. I tried it out today and had varied results with games, after finally learning you have to save the configuration into RAM, and then exit to HDLoader or PS2 Browser, etc to check the results in a game. I've never seen PS2 in progressive mode before, but it doesn't seem to look much different from regular 480i mode. I'll have to play around with it some more. For testing I was using Gran Turismo 4, since you can switch between the display modes in options (better for testing). The one weird thing about my Samsung TV is it doesn't let me set any PS2 game into progressive mode (ex: Gran Turismo 4, Resident Evil 4), even though I am using componet cables and it's set to Component Video Out (Y Cb/Pb Cr/Pr) in the PS2 browser settings. But my TV is supposed to support this according to the manual. Using GSM I was able to force 480p and 1080i modes though, but like I said, there was no real improvement in quality, except for when I was in the HDLoader game list screen (fonts looked clearer).
If possible, please give me some things you need me to test on my standard non-HDTV Toshiba 27AF45C 27" Flat Screen using Composite and Component, since I'm thinking of selling it now. Although, it's going to be hard selling it after seeing how the PS2 looks a lot worse on my HDTV, which of course is to be expected :(.
I would not sell a good working tube that has component for the very reason you mentioned. Cheap fixed pixel TVs have horrible scaler chips, that will make the image look worse than on a SD TV.

If this TV has a VGA input, I'd use that to hook up your PS2, as that input will support more resolutions (even some of GSM's non standard ones) than the component inputs will.
You can also use the game mode on that TV to turn off all post processing, aside from a simple upscale to the panels native rez. This will eliminate lots of lag, but may give worse, or better picture quality.
First, thanks for the answer. I've read almost all the post (at last the fist pages), but since English is not my first languaje, there's lot of thing that I can't catch, I understand almost all the stuff I read, but there's must be something else I don't get, since I can't see why that pixelation occurs.

Another question, If I get the composite-vga cable, would really the quality improve?
Thanks and please, be patient with me!
