So I’ve been playing with widescreen enabled using this hex edit of the iw3mp.exe for quite awhile now: [https://www.wsgf.org/dr/call-duty-4-modern-warfare](https://www.wsgf.org/dr/call-duty-4-modern-warfare) However if I change it after the X install, obviously I get the impure exe error. Is there away around this, or can you include widescreen support in the client side? ---

Vanilla cod4 always supported widescreen resolutions, no fixes needed. Not to mention cod4x. Even at a 21:9 ratio, the sniper rifle scope remains round. There is no need to manipulate iw3mp.exe. ---

You really should try it first before knocking it, on an ultra widescreen monitor it’ll change your cod life. Already had to uninstall cod4x just to get it back. And yes, the game “supports” it, but it stretches the image to accomplish this, this change instead extends the view further out. Just check out the gif on the link I provided for an example. ---

Okay, I won’t argue, do as you wish. I’ve been playing at 2560x1080 (21:9) for several years now. > [@](#): > > People tend to create problems for themselves and then heroically fight them.

Dude, that’s the view I’m talking about, where the edges are obviously incomplete on the main menu so it wasn’t turned on in vanilla, therefore the hex change to enable it … When I installed COD4X it was the old stretched version … so now I’m just confused… lol, no wonder you were like just use the basic one, you had the better one… ---

A couple of years ago, during the next update of cod4x, support for ultra-wide resolutions was added. I have absolutely nothing to do with it. And support for the wide 16:9 format has been there since the game was released. These “obviously incomplete” edges in the main menu are the borders of the background image, which was made for 16:9. In 2007, no one could have imagined that even wider monitors would appear in 15 years) In fact, this is easy to fix, but I have no time to do it. At the moment, all you need to do is install the game (for example, the Steam version), install official patches up to version 1.7, then install the latest version of the cod4x client. Enjoy. ---

See that’s what is weird, I just did a fresh install (CD ISO) with patches, installed cod4x, and it didn’t have the ultra widescreen fix… Maybe I’ll try again some other day then. ---

I think you installed not the latest version of cod4x, try to download from here: [CoD4x Releases - News & Information / Announcements - CoD4x Mod](https://cod4x.ovh/t/cod4x-releases/24)
