don't buy a 144hz monitor to connect to your laptop unless it has displayport or mini-displayport

it does thunderbolt 3 baby

get a computer that can run at 144+ frames before getting a 144hz monitor

get a mouse bungee (optional)

I used to game on a 50-60 fps laptop as well, but this helped my aim quite drastically.

even if you get a mouse bungee a piece of duct tape on the side of your desk does the same job

Not entirely true I have a mouse bungee setup so that my mouse cable barely makes contact with my mousepad which isn't possible by taping the cable to a desk. Could do a wall I guess if your desk is close enough to one.

Your old setup seems fucking awful to play on

hope a desk helps

Mouse bungee is a waste of money. You don't need to buy anything if you have a mouse, mousepad, and a laptop. Save the money for a better upgrade, like a new mouse, better monitor, or better hardware.

How the fuck can a mouse bungee help your aim lmao, you should never buy a fucking mouse bungee its the biggest waste of money ever

It reduces traction, that's why some people like wireless mice

No it doesnt? lol

The fact that people still think mouse bungees are anything but a desk ornament/placebo in 2017 boggles me.
There's literally no way having your mouse tethered at a single point could help you aim better, I don't know how a mouse cable to even get in the way. It's a waste of money.
Also OP why would you need "tips" for playing on a desk?

Your sitting position can be pretty significant towards aim. Personally I never understood the classic "b4nny slouch" because I can't aim at all if I slouch, I have to sit up straight if playing seriously. Also make sure your position allows you to move your arm effortlessly. That said pretty much anything is better than playing from your bed lol

Some mice more than others for sure (it's why stripping a WMO's cable is such a popular mod while nearly unheardof for most other mice, and is why braided cables are generally considered a bad thing), but mouse drag caused by cable stiffness and friction is a very real thing, unless you've got a lubed paracord cable or something. Some mice even have the design flaw where the cable points downwards from the mouse, and will drag immediately. The stitched ends on mousepads can start to fray and start catching your mouse cable too (mostly if it's a braided cable, but still). This is also why playing with wires everywhere in front of your mouse is absolute aids (though the best fix for this is to clean your desk).

A mouse bungee is a $5 solution to at least the issue of friction, and stiffness is less of an issue when the cable's in the air out of personal experience. DIY can make it cheaper too. Mouse bungees aren't as important as actually good peripherals and mousepads, but they also come cheap enough that it's not really a worry if they only slightly make things more comfortable and consistent. It does alter the feel pretty significantly and is all down to preference at the end of the day, but again, it's cheap as fuck to try out.

Mouse bungees are fucking great. Whether you do it with an actual purpose built bungee or a diy option it feels so good to not have your cord dragging. I used to use a large rubber band around the right side of my monitor holding my mouse cord on the top right corner. I use a regular bungee now because my monitor is on a swing arm but the rubber band felt way better. I would argue it helps my aim because I'm not worried about cable drag even though the idea that cable drag is hurting me is partly placebo.

a lot of wrist players like to rest their wrist on the edge of the desk as an anchor and then have their arm going downwards. to do this you use high desk normally (or slouch 24/7). at lan the desk can be lower, so then players just do extreme slouch to give the same effect.

doesn't apply for arm players and other aim styles, you want a lower desk for that. so thats why it feels bad for you.
