If you do go for UHD monitors, be aware of how big you need them to be to read text easily without having to apply a lot of scaling in windows. Large amounts of scaling can lead to UI issues, as mentioned in this forum.

Over several months I progressed from 20" + 24" HD monitors to 24" + 32" UHD to 32" UHD + 40" UHD, and finally settled on two 40" UHD. Finally, I am satisfied. You can get very good deals on Samsung 40" TV's that support 4:4:4 signals and look identical to computer monitors (crisp text, etc). Having the room to scan large quantities of media thumbnails as well as a working timeline is invaluable IMO.

Any model numbers you can point me at?

Sure: samsung 40" UN40NU7100 or older UN40MU6300.

Not saying these are the "best" for colour accuracy HDR picture, etc. Just really good value and make a nice, crisp, large desktop set for your Vegas UI. They do take up a lot of desk space!

I continue to see better images on TVs . There are some HP 20 inch "Computer Monitors" and they are really , really bad . gray level detail is terrible . Me , I recommend getting a TV for the computer . This is a 22 inch 1920 x 1080 TV , which has the same physical pixel size as a 44 inch 4k screen . Clarity is really good on this 22 inch TV . Like they just said , if you go 4k TV , it should be at least 44 inch , so your fine text is still readable .If someone has a 32 inch 4k screen , their pixels will be so small , reading desktop icons will be just too , too tiny . Personally , I can't use larger displays for computer . To much side to side viewing . But do realize , a 44 inch 4k TV has the same physical pixel size as a 22 inch 1920 x 1080 TV , how ever , the 4k screen can hold 4x more stuff . It can hold 4 ( 1920 x 1080 ) screens amount of visual , and with the same readability as the 22 inch 2k TV . 4k should be at least 44 inch . 44 inch 4k would be it . For me , I would then still need to be about the same distance in front of the 44 inch TV to read text and icons , thus causing me too much head\eye side to side movement to see the massive 44 inch screen area , in front of me . For casual use , I did adjust it , using gray bars that I made . The colors are pretty good , so I wasn't concerned about color accuracy . Gray adjustment is the most critical , and those HP monitors can't do it , but this TV can . casual Vizio . If you can't find a 44 inch 4k TV , then get the next size larger , as 40 inch 4k might push the physical pixel size to tiny( Fonts will be more difficult to read ) .

One word of CAUTION when using a TV , instead of a computer monitor . TV's can have high levels of Contrast , compared to a computer monitor . White can be extra intense from a TV . When doing NON critical stuff on the TV , reduce the Contrast which will reduce the White intensity . I use 2 settings . One for full viewing , and one for a dimmer view . The difference is the Contrast and Backlight settings . Contrast from 35 , down to 5 , Backlight from 3 down to 0 . Also , the built in presents are Way Over The Top , when it comes to computer use . The Backlight is really cranked up , in the TV's presets . for full viewing , backlight is set at just 3 . And for dimmed viewing , backlight is set to 0 , with contrast at 5 . That gives a more mellow white level , for mainstream use . To see images and video in their full detail , I use the other settings . Don't burn your eyes out . If your eyes have becomes sensitive to light , it might be because a TV is being used as a computer monitor . Reduce that Backlight level , Reduce that Contrast level and have a reasonable light level in the room . .The TV's built in Preset Movie Mode has backlight at 49 ( way over the Top for computer use . That is even too much for games too ) . To top it off , the bigger the screen , the more light energy it will emit .
