Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * STEP 1 * Age \>= 18 years. Because no dosing or adverse event data are currently available on the use of dabrafenib or dabrafenib + trametinib or nivolumab or nivolumab + ipilimumab therapy in patients \< 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials * Eastern Cooperative Oncology Group (ECOG) performance status: 0 or 1 * Women must not be pregnant or breast-feeding, as the effects of ipilimumab + nivolumab or dabrafenib + trametinib on the developing human fetus are unknown * All females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy * A female of childbearing potential is anyone, regardless of whether they have undergone tubal ligation, who meets the following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months) * The effects of dabrafenib and trametinib or ipilimumab and nivolumab on the developing human fetus are unknown; furthermore, dabrafenib has been reported to interfere with the effect of hormone based oral contraceptives; for this reason and because other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and sexually active males must agree to use at least two other accepted and effective methods of contraception and/or to abstain from sexual intercourse for the duration of their participation in the study, and for at least 4 weeks after treatment with dabrafenib or for 4 months after dabrafenib in combination with trametinib; women of child-bearing potential must use at least two other accepted and effective methods of contraception and/or to abstain from sexual intercourse for at least 5 months after the last dose of nivolumab and/or ipilimumab. Should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately * Patients must have unresectable stage III or stage IV disease * Patients must have measurable disease; all sites of disease must be evaluated within 4 weeks prior to randomization * Patients must have histological or cytological confirmation of melanoma that is metastatic or unresectable and clearly progressive * NOTE: Any patient with BRAF V600 mutant melanoma (whether cutaneous, acral or mucosal primary) who meets the eligibility criteria is eligible for participation in this trial; patients with uveal melanoma are not eligible for this trial * Patients must have BRAF V600 mutation, identified by a Food and Drug Administration (FDA)-approved test at a Clinical Laboratory Improvement Act (CLIA)-certified lab; if test at CLIA-certified lab used a non-FDA approved method, information about the assay must be provided (FDA approved tests for BRAF V600 mutations in melanoma include: THxID BRAF Detection Kit and Cobas 4800 BRAF V600 Mutation Test, Foundation Medicine); prompt information on tumor BRAF mutation status can also be obtained via Novartis "knowNow" Program * Patients may have had prior systemic therapy in the adjuvant setting; however this adjuvant treatment must not have included a CTLA4 or PD1 pathway blocking antibody or a BRAF/MEK inhibitor. Also, patients may not have had any prior systemic treatment for advanced (measurable metastatic) disease * Patients must have discontinued chemotherapy, immunotherapy or other investigational agents used in the adjuvant setting \>= 4 weeks prior to entering the study and recovered from adverse events due to those agents; mitomycin and nitrosoureas must have been discontinued at least 6 weeks prior to entering the study; patients must have discontinued radiation therapy \>= 1 week prior to entering the study and recovered from any adverse events associated with treatment; prior surgery must be \>= 2 weeks from registration and patients must be fully recovered from post-surgical complications * Patients must not receive any other investigational agents while on study or within four weeks prior to registration * Patients are ineligible if they have any currently known active and definitive central nervous system (CNS) metastases; patients who have treated brain metastases (with either surgical resection or stereotactic radiosurgery \[SRS\]) could be eligible; patients must not have taken any steroids =\< 10 days prior to randomization for the purpose of managing their brain metastases; repeat imaging after SRS or surgical resection is not required so long as baseline magnetic resonance imaging (MRI) is within 4 weeks of registration; patients with multiple brain metastases treated with SRS (with \[w\] or without \[w/o\] whole-brain radiotherapy \[WBRT\]), are not an exclusion; patients with definitive CNS metastases treated with only WBRT are ineligible; patients with potential CNS metastases that are too small for treatment with either SRS or surgery (e.g. 1-2 mm) and/or are of uncertain etiology are potentially eligible, but need to be discussed with and approved by the study principal investigator (PI) * Patients must not have other current malignancies, other than basal cell skin cancer, squamous cell skin cancer, in situ cervical cancer, ductal or lobular carcinoma in situ of the breast; patients with other malignancies are eligible if they have been continuously disease-free for \> 2 years prior to the time of registration * White blood count \>= 3,000/uL (obtained within 4 weeks prior to randomization) * Absolute neutrophil count (ANC) \>= 1,500/uL (obtained within 4 weeks prior to randomization) * Platelet count \>= 100,000/uL (obtained within 4 weeks prior to randomization) * Hemoglobin \> 8 g/dL (obtained within 4 weeks prior to randomization) * Serum creatinine =\< 1.5 x upper limit of normal (ULN) or serum creatinine clearance (CrCl) \>= 40 ml/min (obtained within 4 weeks prior to randomization) * Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =\< 3 x ULN (=\< 5 x ULN for patients with documented liver metastases) (obtained within 4 weeks prior to randomization) * Alkaline phosphatase =\< 2 x ULN (=\< 5 x ULN for patients with known liver involvement and =\< 7 x ULN for patients with known bone involvement) (obtained within 4 weeks prior to randomization) * Total bilirubin =\< 1.5 x ULN except subjects with normal direct bilirubin or those with known Gilbert's syndrome (obtained within 4 weeks prior to randomization) * Patients must not have any serious or unstable pre-existing medical conditions (aside from malignancy exceptions specified above), including but not limited to, ongoing or active infection requiring parenteral antibiotics on day 1, or psychiatric illness/social situations that would limit compliance with study requirements, interfere with subject's safety, or obtaining informed consent; therapeutic level dosing of warfarin can be used with close monitoring of prothrombin time (PT)/international normalized ratio (INR) by the site; exposure may be decreased due to enzyme induction when on treatment, thus warfarin dosing may need to be adjusted based upon PT/INR; consequently, when discontinuing dabrafenib, warfarin exposure may be increased and thus close monitoring via PT/INR and warfarin dose adjustments must be made as clinically appropriate; prophylactic low dose warfarin may be given to maintain central catheter patency * Patients must not have a history of or evidence of cardiovascular risks including any of the following: * QT interval corrected for heart rate using the Bazett's formula (QTcB) \>= 480 msec. at baseline * History of acute coronary syndromes (including myocardial infarction or unstable angina), coronary angioplasty, or stenting within the past 24 weeks prior to registration * History prior to registration or evidence of current \>= class II congestive heart failure as defined by the New York Heart Association (NYHA) functional classification system * Left ventricular ejection fraction (LVEF) =\< 45% on cardiac echocardiogram (echo) or multi gated acquisition scan (MUGA) * Intra-cardiac defibrillator * Individuals who are known to be human immunodeficiency virus (HIV) infected are ineligible (note: HIV testing is not required for entry into the study) * Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids, should be excluded; these include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis;

patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible; patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), should be evaluated for the presence of target organ involvement and potential need for systemic treatment; if no systemic immune suppression is deemed necessary they can be eligible * The following medications or non-drug therapies are also prohibited while on treatment in this study: * Other anti-cancer therapies * Other investigational drugs * Patients taking any medications or substances that are strong inhibitors or inducers of CYP3A or CYP2C8 are ineligible * Patients must not have history of retinal vein occlusion (RVO) * Patients must not have evidence of interstitial lung disease or pneumonitis * Patients must not have malabsorption, swallowing difficulty, or other conditions that would interfere with the ingestion or absorption of dabrafenib or trametinib * STEP 2 (CROSSOVER ARMS): The patient must have met all eligibility criteria (except as detailed below) at the time of crossover * RECIST defined measurable disease is not required * Only prior systemic therapy as part of step 1 is allowed; patients who received allowed systemic therapy in the adjuvant setting prior to Step 1 and were eligible for Step 1 are not excluded from proceeding to Step 2 if they meet other eligibility criteria * Malabsorption, swallowing difficulty, or other conditions that would interfere with the ingestion or absorption of dabrafenib or trametinib, or history of retinal vein occlusion are acceptable for patients crossing over to Arm D (ipilimumab + nivolumab) treatment * History of autoimmune disease, excluding interstitial lung disease or pneumonitis, is allowed in patients crossing over to Arm C (dabrafenib/trametinib) therapy * Patients crossing over from Arm A (nivolumab/ipilimumab) to Arm C (dabrafenib/trametinib) who underwent surgery or SRS to CNS metastases need not be off of steroids to start treatment * There is no restriction on serum lactate dehydrogenase (LDH) at crossover * Patients with a history of cardiovascular risks that developed during step 1 of therapy should be discussed with study principal investigator (PI) at time of crossover * STEP 2 (CROSSOVER ARMS): Patients randomized to Arm A on Step 1 must have melanoma that is metastatic and clearly progressive on Step 1 therapy prior to crossing over to Arm C * NOTE: Patients should (if possible) be at least 1 week from documented PD on Step 1 of current study. All sites of disease must be evaluated within 4 weeks prior to registration * STEP 2 (CROSSOVER ARMS): Patients randomized to Arm B on Step 1 may cross over to Arm D at or prior to disease progression * NOTE: If possible, patients should wait to cross over until after the cycle with the next protocol-required imaging assessment is completed; all sites of disease must be evaluated within 4 weeks prior to Step 2 registration * NOTE: Patients should start Arm D treatment at least 1 week after stopping dabrafenib and trametinib, unless otherwise clinically indicated * NOTE: Baseline labs and QOL assessments should be completed, and patients should follow the Arm D schedule * STEP 2 (CROSSOVER ARMS): Patients must have recovered from adverse events (toxicities resolved to grade 1 or less) of prior therapy; patients with immune related toxicities from ipilimumab + nivolumab may continue onto Step 2 even if still on steroids to control side effects, so long as toxicity has resolved to grade 1 or less * STEP 2 (CROSSOVER ARMS): Patients must have discontinued radiation therapy prior to registering to Step 2 of the study and recovered from any adverse events associated with treatment; prior surgery must be \>= 2 weeks from registration to Step 2 and patients must be fully recovered from post-surgical complications * STEP 2 (CROSSOVER ARMS): Patients are ineligible if they have any currently active and definitive CNS metastases; patients who have treated brain metastases (with either surgical resection or stereotactic radiosurgery \[SRS\]) could be eligible to proceed; patients crossing over from Arm B (dabrafenib/trametinib) to Arm D (nivolumab \[nivo\]/ipilimumab \[ipi\]) must not have taken any steroids =\< 10 days prior to Step 2 registration for the purpose of managing their brain metastases; patients with only whole brain irradiation for treatment of CNS metastases are ineligible; patients with definitive CNS metastases treated with only WBRT are ineligible; patients with potential CNS metastases that are too small for treatment with either SRS or surgery (e.g. 1-2 mm) and/or are of uncertain etiology are potentially eligible, but need to be discussed with and approved by the study PI * STEP 2 (CROSSOVER ARMS): Patients must not have other current malignancies * STEP 2 (CROSSOVER ARMS): Women must not be pregnant or breast-feeding, as the effects of ipilimumab + nivolumab or dabrafenib + trametinib on the developing human fetus are unknown; all females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to Step 2 crossover to rule out pregnancy; a female of childbearing potential is anyone, regardless of whether they have undergone tubal ligation, who meets the following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months * STEP 2 (CROSSOVER ARMS): The effects of dabrafenib and trametinib or ipilimumab and nivolumab on the developing human fetus are unknown; furthermore, dabrafenib has been reported to interfere with the effect of hormone based oral contraceptives; for this reason and because other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and sexually active males must agree to continue to use the same contraception requirements as on Step 1 of this study (i.e.: use at least two other accepted and effective methods of contraception and/or to abstain from sexual intercourse for the duration of their participation in the study, and for at least 4 weeks after treatment with dabrafenib or for 4 months after dabrafenib in combination with trametinib; women of child-bearing potential must use at least two other accepted and effective methods of contraception and/or to abstain from sexual intercourse for at least 5 months after the last dose of nivolumab and/or ipilimumab.
