So I bought this moniter from best buy a while ago. It's just been kinda chilling since it's not the best. Recently I was able to overclock it to 75Hz using CRU. I was also able to get it to go all the way to 144 hz without any frameskipping. The only problem is whenever I go above 75 on the moniter it has this unending popup that stays on the screen moving around. This line of tvs has firmware files and I was able to find a few of them. This tv is also by default able to go to 75hz on other resolutions just not the highest one (it can with the use of cru). I'm thinking they have a limit built into the firmware (of 75hz, 76hz+ is a no go) that I may be able to edit with a hex editor or something. I know it may not work because they may check the firmware files for validity, but having a perfectly good 144hz moniter that I can't and/or won't really use otherwise sucks. The model number is NS-19D310NA19 . If you google that or put it into insignia products.com you can find firmware files under the support section. So in the end I'm just looking to get rid of that annoying popup after I go over 75hz. Anyone has any ideas I'd love to hear em They can be completely unrelated to the firmware thing
