I would suggest you might want to consider these high-nit options.

• FeelWorld LUT6 6 Inch 2600nit offers great visibility.
• Desview R6 5.5 Inch 2800nit provides more brightness. Be careful with cable strain.

@Reply #1 - good point! Honestly, those high-nit budget options are decent, but if you're dealing with signal drops, you gotta look at the internal hardware too. Jumpin in here real quick while I've got a break between edits... > and it kept dropping the HDMI signal which was a total nightmare. In my experience, the 6D Mark II can be super finicky with its Mini-HDMI port. It's not just the monitor; it's often the cable tension or the controller in the screen itself. If you want something that actually stays connected without flickering during your Seattle shoot, I'd highly recommend looking at the Atomos Shinobi 5 Inch 1000nit 4K HDMI Monitor. It is only 1000 nits compared to some of those 2000+ ones, but the color accuracy is way better and it weighs basically nothing. I've used it in direct sun with a hood and it's plenty. Plus, the AtomOS software tools for focus peaking are way more precise than the cheap brands. If you want something even more budget-friendly but still solid, check out the Osee T5 Plus 5.5 Inch 1000nit High Brightness Monitor. It comes with a great tilt arm that helps keep the cable secure. One pro tip: dont skimp on the cable. Grab a Kondor Blue Braided High Speed Mini HDMI to HDMI Cable. The braiding helps it stay stiff so it doesnt wiggle in the port as much. I've been through a dozen monitors over the years and the connection is usually where the cheap ones fail first. Check out the community forums on CineD if you want to see the technical latency tests... they're super helpful for spotting the laggy ones before you buy.

• Atomos Shinobi for reliability
• Osee T5 Plus for value
• Use a locking or braided cable

Just catching up on this thread now. Before you go out and buy another screen, I gotta ask... what kind of HDMI cable are you actually using? If its just a thin, generic one, that might be half your problem right there. I remember doing a session a while back where my screen kept flickering because the mini-HDMI port on these Canons is notoriously wiggly. I almost lost my mind trying to keep the signal alive while moving the rig around. Since then, I am super paranoid about signal stability. I would suggest looking into these:

• Viltrox DC-550 Pro 5.5 Inch 1200nit Touchscreen Monitor which is plenty bright with the included sunhood.
• Andycine C6S 6 Inch 2600nit 3G-SDI 4K HDMI Monitor for that extreme outdoor brightness. Honestly tho, make sure to get a SmallRig Cage for Canon EOS 6D Mark II 2045 to lock that cable down. Without a clamp, even an expensive monitor might drop the signal if you bump it the wrong way.
