Hi, picked up one of these in the sale Amazon UK to replace an LG 34UC98 which whilst still fine for most applications was getting difficult to calibrate for Lightroom. I used a Datacolor Spyder 5 pro and was pleased to see that there were no adjustments required to any of the presets on the device. I'm so used to having to spend ages going back and forth with brightness and contrasts that I assumed there was a problem and re-ran :D I've got a Win PC with a 3080 TI Ultra connected on the display port and for day to day use I have Windows display set to 125% as it just makes things a bit easier to read. When I'm wanting to use Adobe for photo proofing and photoshop etc I switch to 100% just for the detail. I also have a MacBook M3 Max which was connected to the old monitor via a CalDigit TS3+ via thunderbolt 3. The G75F doesn't have USBC/Thunderbolt in and the dock only has DisplayPort and USBC out, so I'm looking for recommends for a cable that will support full resolution as I've had no luck with a selection that I've tried to date: \- UGREEN USB C to HDMI 2.1 Cable 8K@60Hz - flat out doesn't work AT ALL. \- 8K DisplayPort to HDMI Cable 2m - 8K@60Hz - I only get 3440x1440 as default and max of 3480x2160 which is not scaled correctly. I get no options for txt size / refresh rate either \- USBC to HDMI I don't check the specs first and is only rated to 4K - basically same output as the DP>HDMI cable but for £6 rather than £20.... I don't mind paying a premium so long as it works; I'm just fed up of buying and returning cables that don't do what they claim to . Regards, and TIA.

I'm happy using a single LG 34" (3440x1440@60Hz). Enough room for 2 pages of A4 size and then some, or e.g. a PDF and some Ghostty splits. And also nice for movies. I usually use my apps in full screen mode. If I ever need more room there's still the possibility of opening the 16" MBP screen (but that happens rarely).

I went from a 34" curved LG ultrawide to a 55" TV. I like the TV way better, but I think a 49" ultrawide monitor would work even better because then my 24" DDU that I have above my TV would be lower and could be more easily seen. Of course a 57" ultrawide monitor would be even better. Lol.

Yeah it’s only 165hz but it’s perfect for my 3080 setup.

I went with a 34 1440p over the 32 4k. I had this exact dilemma and got the 32 4k first 240hz. My graphic card was 4090 and it looked great but fps was under 100 all the time. Switched to the 1440p 34 240hz and absolute love the switch. I get like 160hz+ and it’s so smooth and beautiful when playing cod and Diablo

Hi guys, I just upgraded to an LG 34" 3440x1440 and while I like the format, I just can't deal with the pixel density. I'm on Retina Displays since the 2012 Macbook came out and just can't go back. Hence, I'm gonna return the monitor and get another one. I have access to Chinese brands and there are basically two options: 40" 5120x2160 LG Nano IPS 120Hz 27" 5120x2880 LG IPS 60Hz (600 USD) 32" 6144x3456 LG IPS 60Hz (1000USD - a bit too much for CN gamble) I cant decide between 27 and 40 - I kinda like the widescreen format, but not sure if the the pixel density of the 40 will be good enough? Anyone has experience with a 40" 5k, and can share if they are happy with Pixel density? https://preview.redd.it/w1k5moki26gf1.jpg?width=1179&format=pjpg&auto=webp&s=bf3a3989efbefef96e21afcec98ad94dac03b04f https://preview.redd.it/q1y6t2kj26gf1.jpg?width=1179&format=pjpg&auto=webp&s=e9fcc5c352e1d403eb9610089548a4b99acf39e5
