Don, Yes ,  the resolution 2560x1440 is the better for me and it's for that i search a way to have larger fonts  ! So, thanks for the 3 files but they appeared as "Unavailable"...I had a similar problem with a file i send to Eisenhauer , he ask me to compress it , perhaps the same issue ? 

Guy, Correct, I don't use Eisenhauer's font. Attached are the three .res files from the Ghost Recon\Data\Shell folder. I thought the resolutions 2560x1440 and larger looked really good but it made the font so small I could not read it. font.res IKE.RES STRINGS.RES

Today I hooked up my TV to my computer, and wow—I was able to play Ghost Recon at a resolution of 3840×2560 (4K Plus Ultra High Definition)—the graphics were amazing. It's best to disable the intros. You can do this in the game options, or you can open the options.xml file, find the following line: <ShowIntro>TRUE</ShowIntro>, and change it to <ShowIntro>FALSE</ShowIntro>.

My gr on my 49" monitor was working fine from a full install on line. Now it can't make the switch from intro video to in game video. same with other installs of gr, what the ???  

Thanks for the screenshots ,  i try the 1920 x 1080 , it's not bad but i find the reticle sight a little bit enlarged and less precise than on my screen resolution . And the "display message box all " from Igor i use  in missions are always very big and with txt not centered . As i understand ,you don't use the Eisenauer Font ? I thinks that my .RES files are not good , so can you please send me the three for trial ?
