New monitor

So basically i have just finished my GCSE's and i am considering what to upgrade. Ill be getting some money on results day all dependent on what results i get. One issue i have with my current setup is my monitor. Its a smart TV and is annoying because there is about 2 pixels that don't work due to a scratch on the screen (my 8 year old bro did it). Also it is very annoying as because more often than not i find myself using 2 windows as i use the computer for working and normally need 2 documents open at one time and we have all experienced 2 windows on a 24" monitor and you get my picture. There are two options i have came to a conclusion on, 2 thin bezel monitors or one ultra widescreen monitor. However without knowing what budget i have to work with (until august 20th) and my lack of knowledge on displays i am completely helpless and open to the unforgiving ways of brand marketing. So any advice on any solution would be greatly appreciated.

PS: I hate to be that person who dares comment on LTT but does anyone know what res Luke is using in this https://www.youtube.com/watch?v=Cqj-p2ywA84 as im either a really crappy listener or he doesnt mention it :) thanks
