I have a 1680x1050 60Hz monitor connected vie a HDMI to DVI cable ( HDMI is the video card and DVI to the monitor). Does setting 75Hz actually put through 75Hz to the monitor or is the hdmi side limiting it to 60Hz?

Wow... that's sad. Why does this happen? So even if I "underclock" to 30Hz will it stay at 60?

If you set it to 75 Hz and it works, then that's it. It works. If it isn't letting you, then, yes, HDMI is limiting you. I know that most HDMI revisions are limited to 1080p @ 60 Hz.

Also, I'm not sure what jitpublisher is saying. Refresh rate definitely does something. It's basically how many FPS your monitor can display. If you have 120 FPS in a game, but your refresh rate is 60 Hz, you can only see 60 FPS. If it's 75 Hz, you can only see 75 FPS, and so on.

The refresh in LCD's is definitely something that matters, but it isn't needed to keep a persistent image like CRT's did.

The refresh does a couple things for LCD's:
1) The refresh is there to update the image on the display with the latest info in the display buffer. Without a refresh, you'd have nothing but a single picture on your screen forever.
2) It is also needed to prevent light variance. While LCD's are solid state, they do have issues if they pixels are not updated at least 15 times a second.

As far as HDMI goes, every implementation I've ever seen limits you to 60hz at 1080p, though with a high speed cable, it is possible to make custom resolutions to increase that in some cases.

I believe it's 1.4 HDMI if that makes a difference. Also, it might be a year until I get a 120Hz monitor but would you guys say it's worth spending about 10 euro on a crt? If I can get that crt to 75Hz will it be that much better than lcd? I know of course it will look worse but I'm a more competitive gamer so it won't bother me

While HDMI, even 1.4 (there are a 3 versions of 1.4), may be capped at 60hz in most cases, you may be able to use a DVI-D connection at 720p or some 1024x768, may allow you to reach 75hz. It has on my monitors that I've tested in the past.

I have a 120hz monitor now, however.

I'm a bit confused as to why my monitor handles 75Hz at the stock 1680x1050 rather than 720p. It's just a normal hanns-g monitor, 3 years old. I just find it strange that none of your monitors overclock unless it's 720p but my cheap ass one does.

Anyway, I won't be getting 120hz for a long time. Would you guys say a crt is a big enough difference from a normal lcd even at 60/75Hz? I don't care about visuals only speed and response :D

well if it makes you feel any better my old 17'' Viewsonic from 2003 does 75Hz at its full resolution of 1280x1024 out of the box, it is using dvi though, but still it was pretty nice when most of the others were purely 60Hz...

That's silly. LCD monitors can be 120Hz or 144Hz and it does make a big difference in gaming.
